BMW Service and Repair Redwood City - McLaren F1 - Bosch European Redwood City - (650) 368-3000


McLaren F1 Supercar

It's flying.

An instant after being launched by a hump in the road at over 100 mph, my view of the sky from the central driving position of the McLaren Fl supercar is pure Cinemascope. The moon could be our destination. In that airborne instant, I believe anything is possible. Forget the moon—with an engine this potent, let's aim for Mars.

When the four-point touchdown comes, it is so velvety that the suspen­sion feels as though it might have been designed for landings. Instantly, the sound of rushing air is shattered by a sharp bark from the engine as the $815,000 McLaren is propelled down the blacktop, accelerating at a rate I've never before experienced. Foot down hard, the straight vanishes. As the speedo needle hits 125 mph, an instant shift—so precise and mechanical it's like pulling back a well-oiled bolt on a rifle—brings fourth gear and another disorienting burst of power that thrusts me forcefully back into the tight-fitting bucket seat.



Still we accelerate. Just 5.4 seconds later, a green up-shift light flashes, appropriately positioned at the 7500 rpm redline on the tach in the center of the instruments. Into fifth gear at 150 mph. Still no lessening of acceleration thrust. The car—squat, stable, a green limpet on the road—shoots forward. Maybe there's space before the corner to grab sixth at 180 mph. Maybe.

No. My courage runs out, the sur­vival instinct takes over. Onto the brakes. I press hard, through the pedal's inert feel before they bite to blunt forward movement.

Less than 30 seconds earlier, I'd waited back up the road for an all-clear signal. Even as the BMW V-12 idled evenly at 900 rpm, I could sense its invincibility. The exhaust note might be subdued, but caress the throttle and the revs soar. I can't resist. Nobody could. This engine responds so instantly it feels as if it doesn't have a flywheel, like a racing engine. The induction bellow is almost ephemeral it can be timed so accurately. The tach needle jerks savagely around the gauge, as if directly connected to the crankshaft.

I'm alone at last, able to contemplate the enormity of a car so swift that it demands an utterly different mental approach. The McLaren forces restraint because there is no way to drive it legally—except on an autobahn or a racetrack—and even begin to probe the full extent of its power and speed. It's an event every time you floor the throttle, producing an irre­sistible desire to remain behind the wheel, to learn as much as possible about a car so intense in its focus, so single-minded in its approach, that I'm convinced even a top-ranked driver could own it for years and still not explore the outer limits of its stag­gering performance envelope.

Forget the Jaguar XJ220, Bugatti EB110, Ferrari F40—until now cars deserving to be called rapid. The McLaren blitzes them all. And we have the proof. Confirmed by the Datron optical test gear.

The numbers do the talking: The F1 blasts to 60 mph in 3.2 seconds. The Porsche 959, the previous production-car record holder, needed 3.6 ticks of the watch. We saw 100 mph in 6.3 seconds. The Ferrari F40 took two seconds longer. The McLaren hits 150 mph in 12.8 sec­onds, a smidgen longer than it takes Porsche's latest, greatest 911 to reach 100 mph. Put another way, the McLaren can accelerate as hard at 150 mph as a Ford Taurus can in first gear.

Zero to 200 mph takes 28.0 seconds. What's impressive is the figures show that above 125 mph, the Fl supercar acceler­ates faster than last year's McLaren MP4/8 Grand Prix race car.

The standing quarter-mile is dispatched in a dazzling 11.1 seconds at 138 mph—about a second quicker and 15 mph faster than any other supercar we've tested

Suddenly all the usual measures of per­formance seem mildly laughable. We're talking about a road car that surpasses the performance of most of the racers that will line-up for this year's 24 Hours of Le Mans race.

Top speed? The Fl runs into the 7500 rpm redline in sixth at 221 mph—but it's still accelerating. Gordon Murray, the F1's designer, is convinced that with taller gear­ing, the car is capable of at least 230 mph.

The motivation behind this speed is a normally aspirated, 6.1-liter V-12, custom-designed for the McLaren F1 by BMW Motorsports. It breaks the magic 100-­horsepower-per-liter barrier, yet it is not about power alone, although its 618 hp at 7400 rpm might convince you otherwise.

Helped by BMW's variable valve timing, Paul Roche's masterpiece also pumps out a staggering 479 pound-feet of torque between 4000 and 7000 rpm. At only 1500 rpm, it produces 280 pound-feet. Try trickling along at 1300 rpm in sixth gear and the spread of torque is con­firmed, the flexibility so astonishing that unless you glance at the tach, you have no idea of the engine rpm. Floor the accelerator and while there's a trace of engine knock, the acceleration is still assertive.

Such a tractable nature is confirmed by the top-gear acceleration times. Although the engine is only turning 1000 rpm at 30 mph in sixth gear, 50 mph comes up in only 7.0 seconds. From 50 to 70 mph, the engine has picked up enough rpm and torque that the time drops to a mere 3.7 seconds. A Lamborghini Diablo needs 7.5 seconds to cover the same interval in top gear and the F40 needs 12.2 seconds.

Best of all, whatever the right foot does is instantly translated to the rear wheels in a way no turbo engine can emulate. This combination of flexibility and sheer mus­cle, the perception that the engine is never stressed, together with the howl of a big-capacity V-12 when accelerating and its relative hush at a constant throttle, ensures that this is undoubtedly the finest high-performance production engine in the world.

Problems? Only a reverse gear that's difficult to engage.

You pay a price for this performance at the gas pump, yet the efficiency of the engine, a drag coefficient of just 0.32, and the enormous benefits of a light 2579-pound curb weight mean consumption is reasonable. On a diet of unleaded pre­mium, it still returns 19.3 mpg at highway speeds. Thrash the car and it drops to just 9 mpg.

Crucial to the McLaren's handling excellence are three key factors: the cen­tral driving position, the car's diminutive dimensions, and a unique patented sus­pension system.

The advantages of the central driving position are many: the driver can be posi­tioned further forward, his legs slotted between the wheel arches in two long car­bon-fiber beams that house the controls. The relationship with an F1 racing car is obvious. There are no offset pedals, and the tiny, almost-vertical steering wheel is positioned so the driver's right hand drops from the rim to the alloy gear lever.

From this position and without the hin­drance of an A-pillar, you can see the pave­ment just five feet in front of the car through the huge windshield. You quickly learn that the compact Fl—it's about nine inches narrower and seven inches shorter than a Diablo—can be placed within inches of the apex. And because the driver is sitting in line with the roll center, any impression of body roll—and there is a little—is removed.

Handling? You won't find a finer supercar chassis in the world. There are compromises in building a car to be obe­dient while driving slowly, yet with the stability required to cope with warp speeds and extreme g-forces, but in the McLaren there are few of the design botches we've accepted as normal in cars of this breed. Yes, the suspension is firm, the tires noisy, and the ride at low speeds and on high­ways jiggly (especially for the passengers). Yet on interesting back roads—where it counts—the suppleness and composure are remarkable

There is no ignoring the weight of the steering when parking, but above school-zone speeds, the steering has an almost meaty precision to its feel. Low-speed corners suggest that the steering is low-geared. Wrong. With 2.8 turns lock to lock, the steering is direct and alive, full of feel yet without kickback.

On slow corners, the combination of an exceptional power-to-weight ratio and a driver-oriented chassis allows you to turn into a comer with just a tinge of understeer and then powerslide through it, balancing the car by using both throttle and steering. The power oversteer is so progressive that one does not hesitate to exploit it, despite the consequences of crashing this $815,000 machine.

Ultimately, the McLaren does exactly what it is asked to do. In fast corners, it grips surely and precisely. Unless you have the responses of a Keke Rosberg—one of the F1's early customers—you run out of bravery, as the strength of the g-forces builds up, long before the McLaren loses adhesion or poise.

It is this certain predictability of behav­ior, the instantaneousness of every dynamic aspect, that makes the F1 so secure to drive, yet because the levels of performance are so high, the driving chal­lenge remains intense and involving.

Only in one area does the no-compro­mise approach suffer. Finding the right disc-brake pads to cope with slow driving, and dealing with the rigors of 200-mph stops, means the massive, vented four-caliper but non-assisted brakes feel wooden when the pedal is first pressed upon. They need a strong right foot and most drivers would probably appreciate an anti-lock system.

They need a strong right foot and most drivers would probably appreciate an anti-lock system.


Does the central driving position have any disadvantages? Once you learn the technique of entry, it is—unless you're really bulky—surprisingly easy to get in and out. The secret is to place your bum on the forward edge of the deeply dished left-hand passenger seat (not the right, because of the gear lever) with your legs outside the car. Lean back on both arms and swing your legs into the car, over the hand-brake bank, and down into the foot well. Then swivel your body across and flop into the driver's seat. Then close the scissors-style doors; you can't pull them shut once you're belted in.

Visibility is brilliant up front, but it suf­fers to the rear. There are two interior mir­rors, but with passengers aboard, they are useless. The exterior mirrors only afford a clue of what's going on behind the car. Because the passengers sit beside and behind the driver, conversation can be one-directional. Heat also spreads from the bulkhead into the twin luggage compart­ments—each containing customized leather luggage—and to the inner edge of the close-fitting two passenger seats.

McLaren's obsession with weight has obviously paid off. The company has produced the fastest, most-accelerative production car the world has ever seen. That it is also a marvelous driver's car is beyond dispute. However, in building a car capable of charting territory no road machine has ever broached before, McLaren is also asking the driver to stifle the car's performance, at least on the road. That the McLaren is capable of delivering pleasure even when the driver is skimming its potential is a real measure of its achievement.

There are no plans to sell the supercar in the U.S. because, Gordon Murray says, it would cost $6 million to certify it.

BMW Service and Repair Redwood City - 2013 BMW M6 Coupe [UPDATE] - Bosch European Redwood City - (650) 368-3000


2013 BMW M6


The 2013 BMW M6 is a rolling obscenity – one that begins with the capital letter "F." It is both the act and the exclamation, the curse and the encouragement. It courts no logic. It is all want and no need, and it is unbecoming of the BMW roundel. Whereas the brand's products once strove to unite man and machine in a duet of blissful performance, the M6 seems built solely to stand between the driver and the road. You are very clearly in its way every second you're behind the wheel, slowing it down and generally being the Monday morning to its two-day trance festival. It's clear this car is very fast, but it has no interest in making you fast in the way that the M3 or even the M5 are wont to do.

But somehow, all that doesn't stop the car from stoking every last lick of lust in your gut. A 560-horsepower twin-turbocharged V8 will do that for you.

Driving Notes

I think this may very well be the most beautiful machine in the BMW stable right now. The fascia, wheels and carbon fiber roof of the M line all help sharpen the standard 6 Series nicely, turning the car from an awkward bubble into a lithe and purposeful grand tourer. It snatches eyeballs like a cleptomaniac Doctor Frankenstein at the optometrist's office: with both purpose and glee.

The real magic of this car is at its heart: a 4.4-liter turbocharged V8 with 560 horsepower 500 pound-feet of torque. The thrust out of this engine is fiendish in its delivery, and you can't help but get the sense that the only thing keeping this powerplant from leaping out of the coupe's nose and terrorizing the countryside is you. The car strains against the brake pedal at every stop light, and the exhaust burbles and pops in some of our favorite anti-social tones. It is the rolling embodiment of Skynet.

Our tester came with a seven-speed double-clutch transmission. The logic can be switched between "sane" and "why am I in the next county?" There is no middle ground, but the paddle shifters feel great. The shift lever, meanwhile, might as well have been imported from another planet. In the future. In an alternate dimension. It's that counterintuitive.

Speaking of switches, there are independent controls for the shift logic, dampers and steering. You can save your presets by plowing through the iDrive system or by pressing and holding a button on the steering wheel, but it all feels like an unnecessary added step. The M6 doesn't simply remember which settings the driver preferred from one jaunt to the next. The result is a car that's in your way more often than not. It's either the best or worst first world problem in the history of our species.

BMW didn't hold back with the carbon fiber on this machine. Our tester came with a composite roof and carbon-fiber trim indoors. It originally wore the optional carbon ceramic brakes as well, but some yokel had already roasted the rotors off of the car. BMW went back with steel. At $8,700 for the option, we don't blame them.

This all sounds like a lot of bellyaching, but don't misunderstand. There are only a handful of cars out there that can evoke the sort of emotion this one does, and most of them carry price tags more than double the $123,345 of our tester. That's not saying it's worth the coin, but the car has its place.

BMW informs us the carbon-ceramic brake option was removed due to the fact that that this particular model was manufactured in 2012. The carbon-ceramic rotors were only available on models built in 2013. While the vehicle's monroney showed the option at $8,700, BMW says the brakes are available for $9,250, but are covered under the company's four-year, 50,000 mile maintenance program.

Mercedes Service and Repair Redwood City - Road Test: 2014 Mercedes-Benz CLA 45 AMG - Bosch European Redwood City - (650) 368-3000




 

With the CLA Mercedes opened up a new segment of compact four-door coupes, and not without success! The AMG version has now arrived, complete with the most power dense 4-cylinder engine in the world. We were invited by Mercedes-Benz to take a closer look at the CLA 45 AMG on a drive from Hannover to the new Bilster Berg race track!

The Mercedes-Benz CLA 45 AMG is, mechanically, almost identical to the Mercedes-Benz A 45 AMG which received its official launch around the same time. Both cars feature the new 2.0 litre turbocharged four-cylinder and both produce a substantial 360hp peak power figure. The differences, aside from the bodywork, are subtle but they are definitely present.

The CLA 45 AMG for example features a slightly modified exhaust system with less rasp and crackles that the A-Class. It also differs in terms of the ride quality. With the CLA geared towards those more conservative in taste, the CLA 45 AMG has a noticably less harsh ride. The dampers are slightly softer in the CLA, this is a conscious decision to differentiate the two cars.

Perhaps the most stunning aspect of the car is the bodywork. From the front the CLA 45 looks almost identical to the A45, the slightly lower roof line is the only thing giving the CLA away. From the side and rear however the CLA looks nothing like its hot-hatch brother. The long lines that travel the length of the car indicate that the CLA 45 AMG is meant to appeal as a smaller and cheaper version of the CLS 63 AMG. With the AMG additions, the larger rims and the low coupe stylings, the CLA 45 AMG is a definite head turner. The CLA is actually longer and wider than a C-Class, although you won’t notice it unless you compare the two side by side.

The cosmetic differences are taken care of through larger, deep-gray intake ducts, a twin-blade grille, wider side skirts, a deeper rear bumper and twin chrome exhaust tips. Inside, the CLA 45 AMG is almost identical to the A 45 AMG. It has the same sports seats with alcantara, leather and faux carbon fibre trims. You can order the CLA 45 AMG with a real carbon-fiber trim package if you wish.

As with the A 45 AMG, indicated fuel consumption is an impressive 40.1mpg. This wouldn’t normally be a talking point for a GTspirit review, yet we suspect that the CLA 45 AMG will probably be used as an everyday car. It has to be said, if you manage to keep your right foot from pressing down to hard the fuel economy is indeed quite impressive, however as soon as you put your foot down a bit too much the fuel economy soon reminds you what kind of car you are in.

 
The four-wheel drive system – one of the first system’s fitted to an AMG road car – is an amazing piece of engineering. Most of the time when you aren’t pushing to the limits, it operates sending most of the power to the front wheels. At lower speeds the driver is less inclined to notice the handling characteristics so this doesn’t appear to be much of an issue. Push a little further though and the power starts to move to the middle of the car. It does this in an instant, perfect for pulling into that small slot on a busy roundabout.

As the CLA 45 AMG isn’t naturally aspirated, the power delivery tends to be towards the higher end of the rev range. A a result it feels almost docile to drive at lower speeds creating a quiet interior space for those moments when you require. Efficient mode will add some extra economy for city drivers that aren’t too bothered about driving their CLA aggressively. It utilizes a stop-start mechanism and engages the lowest possible gear. For those that are interested in using the car’s power, it saves vital fuel for the race track or a quiet country road.

Heading out on the quiet roads around the Bilster Berg, the CLA 45 AMG feels lively and rides well. Interestingly, the steering rack is constant and does not adapt to increased speeds which means more lock is required when really pushing the car. As we build speed and head into a combination of corners this becomes apparent, yet the feel is still precise and direct.

The CLA 45 AMG comes with a seven-speed twin-clutch gearbox. It is silky smooth and instantaneous when driving around on country roads and accelerating in the city, occasionally the downshifts appear to take a little too long. Most drivers of the CLA 45 AMG will hopefully not spend too much time driving in automatic mode, but use the flappy paddles instead.

Moving through the corners, the four-wheel drive system starts to impress. It delivers grip right when the car requires it and for short bursts, can infact transfer all power to the rear of the car. The brakes are impressive too, providing a confident and effective bite. Overall, the package is impressive, equal to that of the A 45 AMG yet offering more of a “grown-up” feel.

On the way back to Hannover we had one last change to put the CLA 45 AMG to the test on a stretch of unlimited German Autobahn. The acceleration for a 2 liter four cylinder is nothing short of impressive, and won’t leave you disappointed. Even at higher speeds there is always enough torque available to sprint away. However the stiff suspension takes bumps at higher speeds quite hard which sadly doesn’t make it the best autobahn cruiser.

Ultimately, you can see the thought process AMG employed to come up with the CLA 45 AMG. Essentially it had to surpass everything in the market segment in a package that appeals to all. Offering the A-Class and the CLA-Class together gives a fantastic market reach, if you aren’t sold on the looks of one then you always have the option of the other.

Both the A and CLA can be considered real game changers for Mercedes-Benz. They appeal to a much younger and trendier audience, which brings the brand with the Star a much needed impulse. Hopefully the positive impact of the A and CLA 45 AMG also affects the other cars in the line-up. For a few years I, myself, would never buy a Mercedes, but with the arrival of the refreshing A and CLA I’m for the first time seriously tempted to buy one.

Toyota Service and Repair Redwood City - Toyota GT86 Review - Bosch European Redwood City - (650) 368-3000


Toyota GT86


By that we don’t just mean enduring the interminable period of delays and introductions as journalists before finally getting our hands on a UK-spec Toyota GT86 (although we have had to do just that).

We mean ‘we’ in a broader sense, as in the wait that every car enthusiast with modest resources has had to tolerate before a manufacturer summoned up the necessary gumption to build an authentic, low-weight, low-cost, compact sports car.

The front-engined, rear-drive 2+2 is powered by a 2.0-litre flat-four engine that churns out 197bhp and 151lb ft. A six-speed manual is standard; there's also a six-speed automatic on offer as well.

Despite boasting a heritage that contains the Celica, the Supra and the MR2, Toyota has passed through a period of recent history that has been so mundane that the GT86’s potential place close to our hearts seems almost to be a novelty. 

However, the manufacturer’s three stated criteria for the GT86 (which has been developed in conjunction with the Subaru BRZ) read like a purist’s manifesto: rear-wheel drive, no turbocharging, ordinary tyres - much like the Mazda MX-5.

The objective, it gloriously affirms, was driver-focused fun. No further introduction is necessary.

Delving into the detail typically reveals the devil in Toyota’s vast and intricate economies of scale, but in the case of the Toyota GT86, the use of common parts shrunk to just nine per cent. If proof were required of the manufacturing giant’s enthusiasm for the project, it exists first and foremost in that figure. 

The next number to consider is 86. Just a hat-tip to the AE86, yes? No. The ‘square’ 86mm dimension of both the bore and the stroke of the 197bhp 2.0-litre horizontally opposed four-cylinder engine previously featured in the in-line four that powered the Celica and MR2. Even the car’s prominent, chrome-tipped exhausts are 86mm in diameter.

Toyota’s anally retentive pursuit of numeral significance may seem somewhat trivial, but it’s indicative of a wider effort to get everything on the car just so. 

Subaru’s boxer engine was selected because its configuration meant that it was compact and light, and could be mounted closer to the ground (and further back) for an ultra-low 460mm centre of gravity.

A high-revving unit was specified, so the boxer was modified to allow it to spin to 7400rpm. Desperate to get the flick-of-the-wrist changes right on its reworked six-speed manual gearbox, Toyota went through five separate prototypes. 

Underneath, nothing was permitted to muddy the virtues of the classic front-engined, rear-drive layout. Thinner, lighter body panels were used to keep the GT86’s burden under 1300kg.

The weight has been distributed 53 per cent front, 47 per cent rear – not because it’s physically perfect, but because the engineers found that the slight front bias was ideal for the car’s handling balance.

Likewise, the suspension components, split between MacPherson struts at the front and double wishbones at the rear, have been mounted to take further advantage of the low centre of gravity, and were tuned to allow an intuitive degree of roll on turn-in.

Finally, and encouragingly, there is a Torsen limited-slip differential to help apply a gung-ho degree of throttle on exit.

A cursory, showroom-floor introduction to the Toyota GT86 will likely reveal that the car’s cabin, while offering a concerted step up from theBRZ’s positively skeletal innards, still lacks the plush, polished look that has come to define a European expectation of what sports cars should feel like inside.

The Toyota is hard-edged and flinty to the touch, and it looks it, too. But there is a wonderful schematic rigour to the interior that only really becomes apparent once the model is in motion.

Most manufacturers talk a fine game when it comes to focusing their cockpits on the driver, but the GT86 is as nakedly purposeful as the tail-gunner seat in a B-52.

Characterised by a sublime seating position — offering the lowest hip-point of any Toyota production vehicle — the car trades gun sights for a large tachometer, and then brilliantly orbits every other facet of the architecture around that eye line. 
Toyota GT86

The attention to a functional, instinctive level of detail — so often the subject of empty marketing rhetoric — is comprehensive and remarkably effective. The steering wheel is the smallest ever attached to a Toyota and a horizontal dashboard design has been used to help better communicate mid-bend roll posture.

Soft knee pads have been built into the door trim and centre console to offer support under high lateral loads and there’s a centre line mark on the upper edge of the dashboard that can be seen reflected in the windscreen… The list goes on and on. 

Not every facet is a success. The pedals have been positioned straight on but are too splayed to allow every size of right foot to heel and toe, but the overall effect is so intoxicating that an enthusiastic driver will likely feel compelled to keep his or her jaw clenched in unconscious tribute to the ardent and impeccable nature of it all.

Nevertheless, the GT86 has an awful lot going for it. Further reinforcing its case is a decent list of kit, including dual-zone climate control, a media system with Bluetooth connectivity and cruise control. The only significant option is sat-nav.

Those who want something that stands out a little more, however, can opt for the GT86 TRD. It's mechanically identical to the standard car but comes with bigger alloys, a TRD bodykit and a few other minor tweaks.

The Toyota GT86 falls into the same bracket as we grouped theMercedes-Benz SLK 200 into. Both cars, though not fast, feel like they have a pleasing level of performance. They are slow enough to be able to enjoy on the road for more than just a second or two’s burst of throttle, but quick enough for necessary overtaking. 

Therefore, don’t be put off by the fact that, on paper, it looks decidedly under-nourished compared with its price rivals and dispatches the 0-60mph sprint in ‘just’ 7.4sec.

A similarly priced hot hatch like aVauxhall Astra VXR or Renault Mégane RS will not only give you at least 60 extra bhp, but they also come to you more easily than in the Toyota, whose engine asks you to work it to 7000rpm for its peak 197bhp, and even to 6400rpm for its 151lb ft peak of torque.

Truth be told, a less costly Renault Clio RS is a closer performance rival. But to dismiss the Toyota on that basis would be a mistake.
Toyota GT86

Its performance isn’t about numbers; in the same way that a Renault Clio RS is more fun than an Astra VXR, or in the same fashion that the Morgan 3 Wheeler we tested wormed its way into our hearts despite its modest poke. It’s about feel, communication and enjoyment. 

Make no mistake: the GT86’s performance is worth working for. And you do have to work it. Throttle response is crisp, the gearshift is positive and precise (if not entirely notch free) and the flat four makes a solid rasp once you wind it up, as you have to, to make swift progress.

All sports cars were thus once. We didn’t mind then, and we don’t mind now. Thanks to its 1235kg tested weight, the GT86 stops pretty well, too, and it resisted fade comfortably during heavy runs on track in warm weather.

Buyers interested in the automatic version would be well advised to test one first, however. It changes smoothly and relatively quickly but it's not as crisp or as fast as a dual-clutch gearbox.
 
Toyota GT86

All it takes is 50 metres – a jaunt out of a car park, just a short roll – to know that you’re in the presence of an exceptionally well sorted piece of kit with the Toyota GT86.

From the lowest of speeds, the GT86 rolls with a controlled comfort allowed by 215/45-section tyres and fine damping of its body. It steers with slickness, total linear accuracy and fine weighting. 

They all combine to make the GT86, ironically, one of the more relaxing sports cars to drive.

Because everything happens as you expect, and each control responds just so to each input you make, it’s an extremely amiable companion, despite cabin noise levels that are much higher than average (forgivably, we suspect, because of a weight-saving reduction in sound proofing).

However, the really impressive stuff comes when you ask more questions of the chassis. During the GT86’s time with us, texts from testers telling the rest of us that they were “going to be late; taking the scenic route” became commonplace. The GT86’s slickness of steering, tightness of chassis control and general love of corners wowed us all.

Key to it are the modest tyres. That 215/45 R17 Michelin Primacys leave the GT86 looking under-tyred is a sign of the times. Yet at the track, the GT86 was still capable of holding 0.99g through corners on the dry handling circuit, on a steady throttle.

The fun comes on less steady throttle openings, mind you. Lean on the brakes on the way into a bend, get busier with the right pedal mid-corner, and the GT86 displays a willingness to adjust its line that makes every quiet roundabout a joy.

And therein lies the Toyota GT86’s real brilliance. It is at once poised, precise and agile yet also willing to indulge its driver with oversteer. The choice is yours. Every corner is a blank page, and the cars that give their drivers such options are rare things indeed.

Audi Service and Repair Redwood City - Road Test: 2012 Audi S8 - Bosch European Redwood City - (650) 368-3000



Road Test 2012 Audi S8

 You are looking at the newest edition of the Audi S8, a top-of-the line S-badged A8 powered by a twin-turbocharged 4.0 liter V8 claiming the number one position in the market of über-limos and ultra-comfortable power sedans. Audi offered us a weekend of S8 pleasure surrounded by the ultimate comfort, refinement and high-tech multimedia currently available in the German stable.

For its first two generations, the S8 was an executive touring car. The new two-tonne model offers a similar feeling, but also a hell of lot more. The 2012 S8 has made a giant leap from its predecessor and is capable of delivering more power, speed, refinement and agility with less fuel consumption and noise levels.

The new 2012 Audi S8 did not offer us the very first taste of Audi’s new V8 engine, which also powers the S6 and S7. We drove both S-models earlier this year and experienced the excellence of the smooth power plant featuring Audi’s “cylinder on demand” technology used under part load for a lower fuel consumption. It simply means that electronics shut down cylinders 2-3-5-8, while cruising and using light throttle responses. The system works unnoticed.
 
Road Test 2012 Audi S8 01

The power offered from the engine dishes out its 520hp at 6,000rpm and 650Nm between 1,700 and 5,500rpm to all four wheels. That’s enough power to slingshot you from 0-100km/h in 4.2 seconds – quicker than the rivals from Jaguar and Mercedes. The top speed is electronically limited at 250km/h.

Excellent numbers, but those are only memorized after a full experience behind the steering wheel. The acceleration after pushing the throttle and the initial pause while the gearbox shifts down creates a responsiveness and acceleration no one has never seen before in any S8. It is exhilarating! The active engine mounts and noise cancellation with four microphones inside the cabin allow the S8 to do its catapulting task in relative silence.

The engine steps off the line gracefully and spins smoothly to the redline without the slightest hint of turbo lag. A self-locking center differential, limited-slip rear differential with torque vectoring and an eight-speed automatic let the drive train stand out from direct competitors. The muffled growl from the quad end pipes under full throttle, smooth and deep, accompanies the grandeur of the twin-turbo V8.
 
Road Test 2012 Audi S8 02

The handling and ride quality fits the S8 in an excellent manner. The luxury power sedan is capable of eating stretches of highway with ease while accessing loads of comfort, even on the optional 21 inch five-spoke wheels fitted to our tester. Cornering is not the S8′s favorite habit due to the car’s considerable weight and size. The steering has a little shortage of self-centering action, but this seems to be part of any current Audi S-package. The S6 and S7 had the same! Still it delivers accurate steering, excellent body control, and supreme stability.

Inside the cabin, there is loads of refinement and an impressive list of high-tech gimmicks, like a MMI infotainment system with a pop-up, eight-inch display, in-car wireless internet, and Google Maps imagery. You also have a 1,400 watts Bang & Olufsen surround sound audio system, speech recognition, a night view camera with pedestrian recognition and all-around camera view system. The equipment list is as impressive as you’d expect from a top-of-the-range limo.

The excellent interior features leather, visible carbon fiber and aluminum trim standard on the dash and doors, although wood can be specified in place of the carbon. The 22-way adjustable leather sport seats offer massage capability, cooling and heating (massage and heating also in the back). The rear passengers have electric blinds for the rear windows and a central console offering access to their own multimedia and/or climate control system. Upon request Audi installs a cool box for your everyday refreshment.

The Germans have built a brilliant luxury sedan. The combination between refinement, luxury, comfort, technological highlights and that V8 engine are a sheer example of how good Audi’s can be! The 2012 model series is the benchmark in a market of powerful, comfortable super sedans capable of transporting the driver and his passengers in the most brilliant way possible.

Yes, the Audi S8 should have had a bit more intensity and driver involvement, but the S6 and S7 aren’t any different on this subject. This is what you get from the Germans headquartered in Ingolstadt. So did we like it? Personally we think that the S8 has enough driver involvement to call it excellent, technical enhancements to call it stunning and an engine performance which is exhilarating.

Range Rover Service and Repair Redwood City - History lesson: the Range Rover - Bosch European Redwood City - (650) 368-3000



 

Wednesday 17th June 1970 is not a date etched on many minds. It is however the day that the Range Rover was announced to the worlds motoring press. Unknown to the Rover Company, it was a vehicle that over the years would totally revolutionise the leisure car market, a world beater.

The story had started a lot earlier. The Rover company had been "toying" with the concept of a more "upmarket" Land Rover Estate car since the early 1950s. The first project was named "Road Rover", and several prototypes were built using the P4 "Auntie" Rover car chassis. Towards the end of the 50s the project ground to a halt, and was shelved.

It remained dormant for a number of years, until 1966 when engineers Spencer King, and Gordon Bashford decided to set about designing a Luxury Land Rover estate car, using the powerful but relatively lightweight V8 engine, based on the a 100" wheelbase chassis.
August 1967 saw the completion of the first prototype, bearing chassis number 100.1

(100 inch chassis number 1), and the registration number SYE 157F. This was followed in 1968 by chassis 100.2 registration ULH 696F, this was a left hand drive version. Sadly both of these have long since been scrapped.

By late 1969 the prototypes had served their purpose, and "Line production" was ready to start, and a new chassis numbering scheme was introduced, using the numbers:

355 to signify "Home market RHD",

358 to signify "LHD"

356 to signify "RHD Export"

573 to signify "CKD" kits.

25 of these "Pre-production" Range Rovers were built during late 1969 and early 1970. They were registered in London, with the registration number sequence YVB 151H to YVB 175H.
The first three were registered on 2nd January 1970.

The name "Velar" (Vee Eight Land Rover) was used on these pre-production vehicles to confuse inquisitive observers about their true identity before the Range Rover was officially unveiled.

In May 1970, a batch of 20 production standard Range Rovers were built, 5 red, 5 white, 5 blue and 5 green.

In total 86 Range Rovers were built in 1970.

When the Range Rover made its debut in 1970 it was available in just one guise - a three door estate with four speed manual gearbox and permanent four wheel drive. The Range Rover was, and still is, unique, so much so that one model was exhibited at the Louvre as an example of modern sculpture. However, despite its more luxurious image the emphasis was still on practicality - the original brouchure extolled the virtues of a hoseable interior while the British Trans Americas Expedition proved the new vehicle was every bit as tough as the Land Rover by crossing the Darien Gap in 1972.

Over the years, the choice of Range Rovers has been extended to meet public demand. A four door model was launched in 1981 and automatic transmission the following year. In 1983 a five spped manual gearbox was introduced. Two years later the Range Rover Vogue received fuel injection, and in April of 1986 the Range Rover Turbo D made its debut. March 1988 saw the launch of Range Rover's new flagship, the Vogue SE, which featured air-conditioning, 4 speed automatic transmission, Connolly hide upholstery and electric tilt slide sunroof, all as standard.

At the 1988 British Motor Show, a chain drive transfer box and a viscous control unit were introduced. The VCU locks the centre differential automatically the instant that traction is lost.

In 1990 major improvements included the introduction of the 3.9 litre V8 engine replacing the 3.5 litre unit, the VM 2.4 litre engine increased in size to 2.5 litres, and anti-lock brakes introduced as an option on all models, standard on Vogue SE.

The Range Rover received the most significant changes ever undertaken to its suspension for the latest models which went on sale in the UK in January 1991. The key elements of the new suspension package included the fitting of anti-roll bars increasing roll stiffness by 25%. The result is that body roll is reduced on cornering, but the traditional luxury feel of complient suspension is maintained as is the Range Rover's unparalleled off-road performance. 

The final developments of the original Range Rover came in 1994 with the introduction of dual airbags - a first in the sport-utility market. Just a few months later, the New Range Rover made its appearance and the old one was renamed the Range Rover Classic to avoid confusion in markets where both were sold together. The last of the original Range Rovers was built in 1996, bringing to an end nearly 26 years of continuous production.
The original Range Rover made its mark with the emergency services, as well as in the luxury car class. By the time it went out of production, the original Range Rover had come to represent an unparalleled combination of character, capability and cachet to millions of people in all walks of life.

Evolution

Through out nearly 26 years of production the Range Rover was built in 7 Phases. Here is a brief summery of each.

Phase 1: June 1970- July 1979. 2 Door Models only. Basic trim & Spec. 1975 options package introduced, it included cloth seats, power steering, tinted glass and front inertia reel seat belts. 1978- Overdrive option.

Extras included electric windows, 3 spoke alloy wheels, walnut door cappings and air con. Higher compression engine standardised with more torque. Three speed automatic (from Chrysler) transmission became an option in 1982. Front arm rest option introduced. shorter gate five speed gear box took over the four speed in 1983, Also the exterior door locks were moved up to door handles. Central locking was standardised. The 2 Door model remained at Phase three spec as the 4 door moved on to Phase four.

Phase 4: June 1984- Oct 1985. 4 Door only. Front quaterlights deleted, new recline able, height adjustable front seats, with separate seat belts and head rests. New door trims with built in speakers.

Jaguar Service and Repair Redwood City - History lesson: the Jaguar F Type - Bosch European Redwood City - (650) 368-3000




 Few cars sound better than an F-type at full chat (© Jaguar)

 

Jaguar is one of the most famous sports car makers in the world. Indeed, brand chief Adrian Hallmark says it was one of the founder members of the sports car arena – the legendary E-type precedes even that sports car icon, the Porsche 911.

But between 1974 and 2013, Jaguar didn’t even sell a sports car – something as unthinkable to Hallmark as Ferrari or Porsche not selling a sports car. It wasn’t through lack of trying though, as we shall see. There’s more to the Jaguar sports car story than you’d think…

Few cars sound better than an F-type at full chat

Whoever tuned the F-type's exhausts deserves a medal. Even the base V6 models sound like an angry hornet snorting supercharged narcotics - and the V8 S range-topper bellows like an American muscle car. The gruff acoustics are intrinsic to the appeal of the F-type.

Such great aural pleasure is mostly down to the switchable exhaust. Flaps in the pipes open up at around 3000rpm to let the exhaust gases rip straight through - hell hath no fury when it's released to bypass the silencer... The F-type pops and cackles, booms and crescendoes like something born in Maranello, not Coventry.

Now you see them, now you don't: magic disappearing air vents
Few cars sound better than an F-type at full chat (© Jaguar)

Jaguar design chief Ian Callum has form here. The 2008 XF sported air vents which rotated around when you first started the engine. Callum called it the handshake.

The F-type serves up a new twist on robotic air vents. The central air vents atop the dashboard are mostly hidden, rising up only when the on-board computer determines extra ventilation is necessary.

There will be a Jaguar F-type RS version

Few cars sound better than an F-type at full chat (© Jaguar)

Hard to believe, but Jaguar thinks there is room for an even faster, more focused F-type than the V8 S model MSN Cars drove at launch (read our F-type review here). Yes, the one which already hits 60mph in 4.2sec. Senior sources at Jaguar have confirmed to MSN that an RS model is being worked on. 'It looks very good in French racing blue,' said our mole.

The RS model is likely to feature a much more powerful engine, according to Autocar magazine. It reports that a power output of 600bhp is possible and weight will be carved away too. We dread to think of the bills for over-stressed rear Pirelli tyres...

The Jaguar F-type nearly didn't have red paint
Few cars sound better than an F-type at full chat (© Jaguar)

A small revelation made by Jaguar design chief Ian Callum (above): the new F-type nearly didn't have red paint on the options list. In the event, punters can now choose between Italian Racing Red and Salsa Red but there was originally no scarlet option planned.

'We can only have 16 paint colours in our Castle Bromwich factory,' he told MSN Cars. 'By the time you've put in the basic paints we need - such as the greys, whites, a black metallic for Europe and the solid black popular in the US - there was no room for red. But it really suits this car and I fought hard for it. We had to sacrifice a pair of other colours, but we now have two reds on the colour charts. It's one of the most popular colours, judging by our order books.'

Of course, if your pockets are deep enough, you can order any colour you like from Jaguar's Engineered To Order customisation programme. Walk in and match the colour of your F-type to the hue of your favourite suit? That'll be £8,000, please sir.

It's made almost entirely from aluminium

The F-type is unusual in this class for being made almost entirely out of aviation-spec aluminium. Jaguar has become a leading expert in the material and has been making its XJ and XK models from the stuff for years at its Castle Bromwich factory in the Midlands.

The aluminium construction is good for performance, economy, handling and recycling - it's a virtuous circle where less mass equals more goodness all round. It also means that the F-type is glued and riveted together - just like an Airbus.

The F-type's rear lamps are modelled on an E-type's
Few cars sound better than an F-type at full chat (© Jaguar)

Jaguar design chief Ian Callum is not big on sentimentality, but when you work for a company whose history is as storied as Jag's, you have to expect some retro touches.

The F-type is wholesomely new and modern, in the whole, but Callum acknowledges the oval grille references the 1968 XJ's, while those narrow rimmed rear lamps are a nod to the chrome bumper bars on an early E-type. Neat, eh?

Audi Service and Repair Redwood City - History lesson: the Audi Q5 - Bosch European Redwood City - (650) 368-3000





 2013 Audi Q5

 The Audi Q5 is a mid-size luxury crossover with seating for five passengers. The Q5 is based on the A4, and it competes with alternatives like the Mercedes-Benz GLK, BMW X3, Volvo XC60, Cadillac SRX and Land Rover Range Rover Evoque.

With the Q5, Audi doesn't stray too far from the successful luxury-crossover formula. The platform may be A4, but the Q5 has better ground clearance and comes standard now with Audi's quattro all-wheel-drive system for great all-weather traction.

The Q5 arrived in U.S. showrooms in late 2009 as a 2009 model, and was left virtually unchanged for the 2010 model year, in a single configuration: as a five-door wagon with a V-6 engine, an automatic transmission, and all-wheel drive. This initial Q5 had a smart mix of luxury and performance off the bat. The heart of the performance package was a 3.2-liter, 270-horsepower V-6, teamed up with a six-speed automatic with manual gear selection and all-wheel drive. Still in the lineup today, it's a powerful engine but has a little more volume and vibration than expected. Gearchanges are smooth enough, and Audi estimates a 0-60 mph time of 6.7 seconds.

In the 2011 model year Audi added a new drivetrain option to the Q5 mix--a version of the VW/Audi corporate four-cylinder with turbocharging and 211 horsepower. Mated to a six-speed automatic and front-wheel drive, this is the Q5 we recommend unanimously. It feels lighter on its feet, produces much better fuel economy numbers than the V-6 (20/27 mpg versus 18/23 mpg) and has a sticker price that's much lower, though it's rare to find a Q5 priced below $40,000 with popular features.

The Q5's chief dynamic liability is its fairly stiff ride, and Audi's adjustable Drive Select suspension and steering are some of our least favorite applications of electronics. The Q5 will tow 4,400 pounds and has nearly 8 inches of ground clearance, so mild off-roading isn't entirely out of the question. Most versions come with luxury features like leather, Bluetooth, and satellite radio; a panoramic sunroof is a great addition to the options list.

The Q5 has a long list of safety equipment including front, side and curtain airbags; stability and traction control; and parking sensors and a rearview camera. The Q5 also has received strong crash-test scores from the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS).

For the 2013 model year, the Audi Q5 carries over its turbocharged 2.0-liter four-cylinder, but offers as a high-output option its 272-horsepower supercharged 3.0-liter V-6 coupled to an eight-speed automatic--and introduces a new Q5 Hybrid to the mix. The hybrid blends the turbo four powertrain and eight-speed automatic with lithium-ion batteries and a 54-hp electric motor for a net of 245 hp, a 0-60 mph time of 7.1 seconds, and combined gas mileage of 26 mpg. Quattro all-wheel drive is standard with the hybrid, as it is with the other powertrains.

Audi has talked about bringing diesel version of the Q5 to the American market. It could be an easy transatlantic journey, since the powertrain's already offered in other markets. But it now appears the diesel won't arrive until the next Q5 goes into production in Mexico sometime in 2016.

The updated Q5 also now offers as optional equipment Audi Connect 3G wireless Internet service, Google Earth mapping, adaptive cruise control with full braking at speeds of up to 19 mph, and a rear-seat entertainment system.

Mercedes Service and Repair Redwood City - History lesson: the Mercedes M-Class - Bosch European Redwood City - (650) 368-3000


2013 Mercedes-Benz M-Class ML350 4MATIC 4dr SUV Exterior
 

While Mercedes-Benz will always be a quintessentially German automaker, its M-Class SUV has always been an American at heart. To begin with, it's built in Alabama and has been since it first burst onto the scene as one of the first luxury SUVs. The U.S. of A is also the M's primary market, as its sizable dimensions and traditionally thirsty engines play much better in Frankfort, Kentucky, than they do back in Frankfurt, Germany.

Regardless of its origins, however, each generation of the Mercedes-Benz M-Class has been better than the last. This is especially true of the second generation, which replaced the original model that soldiered on through eight years of subpar reliability and build quality. As such, used shoppers are urged to consider the M-Class from 2006 and later. If you're interested in a new model, however, the latest, third-generation M-Class is a subtle evolution of the previous one, upping the ante with even more power and features. It's a solid choice for a midsize luxury SUV, but there are many worthwhile and cheaper competitors in the premium SUV segment. As such, it's certainly worth a look around before you settle on this Germanic American.

Current Mercedes-Benz M-Class
The Mercedes-Benz M-Class midsize luxury SUV has been completely redesigned for 2012. The exterior styling strikes a balance between traditional M-Class cues and the latest ones from the Mercedes-Benz line. As always with a Mercedes, however, it's the quality of construction and all-around feeling of solidity that make it stand out in a crowd. Other key strengths include its diverse engine lineup, comfortable seating and excellent brakes. With only five seats, however, it's less family-friendly than some rivals and its price can be considered quite expensive.

The current M-Class is available in four different trim levels. The ML350 comes with a 3.5-liter V6 that produces 302 horsepower. The ML350 Bluetec has a 3.0-liter turbodiesel V6 that utilizes 50-state-legal clean-diesel technology. It produces 240 hp and a massive 455 lb-ft of torque, while returning a commendable 22 mpg combined. The ML550 comes with a twin-turbo 4.7-liter V8 good for 402 hp. A seven-speed automatic and 4Matic are standard on all.

All of the above models come similarly equipped with standard items like a sunroof, a power liftgate, heated power front seats, the latest COMAND electronics interface, Bluetooth and an emergency communications system. The options list is filled with just about everything else you could expect from a midsize luxury SUV, though its Dynamic Handling package stands out with its 20-inch wheels and adaptive air suspension that improves both ride and handling.

Finally, there's the ML63 AMG. It gets a 5.5-liter twin-turbo V8 good for 518 hp, or 550 when you opt for the AMG Performance package. Besides its extra power, it also gets active roll stabilization, sportier suspension and steering tuning, 20-inch wheels, stronger brakes and special interior trim.

In reviews, we've been impressed by the Mercedes-Benz M-Class' brisk performance and strong brakes. Handling is confident enough around corners, but the electrically assisted steering is a little too light in effort and lacks the subtle feedback we've come to expect from Mercedes-Benz. Interior quality is very good, as expected, though the more rounded dash design reminds us more of the distantly related Jeep Grand Cherokee in its appearance than its squared-off Mercedes siblings. Overall, the M-Class is solid choice for a luxury SUV, but as there's so much to choose from in this segment, taking a look at a few different competitors as well is a good idea.

Used Mercedes-Benz M-Class Models
The previous, second-generation M-Class was produced from 2006-'11. Though similar in appearance to the current model, this M-Class differs in its engine choices, hydraulic versus electric steering, slightly lower-quality interior, and electronics controls that were less user-friendly than those of its contemporary competitors.

This generation was introduced with only two trims. The ML350 came with a 3.5-liter 268-hp V6, while the ML500 was powered by a 5.0-liter 302-hp V8. Both came similarly equipped.

The next year saw two additional models join the line. The ML320 CDI featured a relatively fuel-efficient diesel engine (215 hp, 398 lb-ft of torque) that didn't have California emissions approval, while the performance-oriented ML63 AMG came with a 6.2-liter V8 good for 503 hp. It also included a number of other performance and handling upgrades.

The ML550 replaced the ML500 for '08, boasting a 5.5-liter V8 good for a much healthier 382 hp. The following year saw the advent of the 50-state-compliant and renamed ML320 Bluetec, along with a base rear-wheel-drive ML350. Every ML also received a face-lift front and rear and an available updated COMAND system with Bluetooth phone connectivity.

For '10, the diesel model became the ML350 Bluetec and received a smidge more torque, but the bigger news was the addition of the ML450 Hybrid. Featuring a gasoline-electric hybrid system co-developed with BMW and General Motors, this ML featured a 3.5-liter V6, a pair of electric motors and an advanced transmission for a total of 335 hp. It achieved 22 mpg combined, which is good, but the cheaper Bluetec managed 21.

In reviews, our editors found the second-generation M-Class imparted that feeling of impenetrable solidity one expects from Mercedes-Benz. With the optional air suspension, the ride quality was impressively supple. Behind the wheel, one will find plenty of room and excellent support from the premium multicontour seats, as well as superb cabin materials. Major downsides included fussy electronic controls, pokey acceleration with the V6 engine, and higher ownership costs than some other luxury SUVs.

The first-generation Mercedes M-Class debuted in 1998 with the ML320, which was motivated by a 3.2-liter V6 with 215 hp. More standard equipment was added in 1999, as well as a more powerful and luxurious V8-equipped ML430 model. Detail improvements in 2000 included an interior freshening and optional third-row seating on all M-Class models, and in 2001 the TeleAid emergency calling system became standard across the lineup. These early ML models suffered from extensive quality-control issues that often resulted in expensive repair bills, so we wouldn't recommend them as used-car purchases.

The Mercedes-Benz M-Class was reworked and improved in 2002 with the modification of more than 1,100 parts and the substitution of the ML500 for the previous ML430, now featuring a 5.0-liter V8 packing 288 hp. Telltale signs included new bumpers, clear-lens headlights and restyled mirrors. In late 2003, the ML350 slotted in above the ML320, featuring a larger 3.7-liter 232-hp V6.

Mercedes was also first to market with a high-performance luxury SUV, offering the ML55 AMG from 2000-'03. Sold in limited numbers, this pricey ML had a 5.4-liter V8 good for 342 hp and 376 lb-ft of torque, along with a sport-tuned suspension.

Mercedes Service and Repair Redwood City - History lesson: the Mercedes G-Class - Bosch European Redwood City - (650) 368-3000




Mercedes G Class
 

We recently opined that there's no godly reason to buy a G63 AMG. The styling's antiquated, it's utterly terrifying to drive and it's horribly expensive. Truly, horribly expensive - Mercedes has announced today that the G350 Bluetec will start from £82,945, and the G63 AMG from... Wait for it... £123,115. One hundred and twenty three THOUSAND pounds...

But that hasn't stopped swathes of you commenting that you still want one. Badly. So we thought you deserved a bit of a G-Class history lesson (it stopped being the G-Wagen in 1998, by the way)... 

Darling of oligarchs, arms dealers and Richard Hammond, MB's wheeled prison has, unsurprisingly, very military roots. More surprisingly, it's not actually a dyed-in-the-wool Benz.

Back in the seventies, the Shah of Iran suggested to Mercedes that it might be a nice if it built an SUV (née 4x4). MB promptly hopped into bed with Austrian military vehicle manufacturer, Steyr-Daimler-Puch, and started creating the "Geländewagen" (German for cross-country vehicle) for civilian and military use.

A development program rumbled through most of the seventies, including excursions to German coalfields, the Sahara desert, and the Arctic Circle. And Steyr-Daimler-Puch began hand-building the G in the same Graz factory they're made in today, ready for its 1979 launch.

When it arrived on sale you could choose either a short (2400mm) or long (2850mm) wheelbase. The former came in two-door ragtop or wagon flavour, but the big ‘un was only available as a four-door wagon. You could also get both of the estates as windowless two-door vans, called Kastenwagen.

Underneath, they were sturdy old Hectors. The cubic body sits on top of a ladder chassis, under which SP fitted three fully locking differentials. Engine-wise, the lineup was all Mercedes. You could pick from a selection of three petrols (a 2.0-litre and 2.3-litre four-pot or a 2.8-litre six) and three diesels (a 2.4-litre four-cylinder diesel, or a 2.5-litre and 3.0-litre five-pot). Incidentally, all of the units appeared in one of 
James' favourites, the Mercedes W123.

The amalgam of military underwear and German oily bits was a successful one, and it soon found favour with the military - in its career, it's seen service with 63 armies, and Mercedes has had to promise NATO that it'll carry on building them till 2025. But there was a problem. When MB started developing the G, the man they thought would buy it had straw in his mouth, not a plum. And even though it offered some concessions to comfort with its civilian versions, utilitarian innards and prosthetic-limb beige was still very much par for the course, despite a comparatively high price tag.

This would all have been fine if the luxo-SUV hadn't just been invented by Range Rover. Obviously, MB wanted in, but instead of developing an all-new model to take on the RR, it threw some its saloon-car spec into the G.

The first major refinements came in 1981 and included an auto' box and air conditioning; a year later it got comfier front seats lifted from Benz's car line-up, auxiliary heating and wider tyres. Having generated some column inches with a Paris-Dakar rally win in ‘83, MB kept piling in the kit; by '87 it was fitting the G with electric windows, a power antenna and luggage covers.

In 1989 it got its first full pimp out - to celebrate the G's tenth anniversary, in came permanent four-wheel drive, wood trim, ABS, a top-spec interior and three electronically-locking differentials.

But in 2004, everything changed. The post '90 Gs were definitely luxurious, but they weren't quick, and its esoteric customer base started noticing. Mercedes' solution was simple - hand it over to in-house tuners, AMG. Subsequently, its squeezed in a 5.4-litre supercharged V8, 5.5-litre twin-turbo V8 and now there's the latest offering - a 6.0-litre twin-turbo V12, which produces 612hp and 737lb ft. In a car with a Cd of 0.53. That's the same as a 1969 Ford Torino convertible.

But clinging on to its antiquated styling, refusing to compromise on its off-road ability and stuffing it with Mercedes finery - and AMG power - has somehow kept the G alive, visually unchanged, for the last 33 years. And despite everything 
we're rather pleased it exists. Because it really, truly, shouldn't, even if it can do this.
