As we've speculated for years, Jaguar-Land Rover has a new
inline-6 engine, and on Tuesday the company announced it will first find a home
in the Land Rover Range Rover Sport HST.
The new 3.0-liter turbocharged inline-6 replaces the
dated supercharged
3.0-liter V-6 and is part of the Ingenium family of engines The supercharged
V-6 suffers from numerous inefficiencies, including the fact that it is
actually a V-8 that simply doesn't use two cylinders. The inline-6 shares
components with the company's 2.0-liter inline-4 engine, itself part of the
Ingenium engine family.
Unlike the inline-4, the new inline-6 features a 48-volt
electrical system that gathers energy during braking. It also has an electric
supercharger that spools up to 65,000 rpm in just 0.5 seconds to virtually
eliminate turbo lag. The electric supercharger then hands off to a twin-scroll
turbocharger that is supported by continuously variable valve lift. The 48-volt
electrical system also helps power the automatic stop/start system. The
efficiencies and mild electrification help improve fuel economy over the
previous supercharged V-6 engine by about 20 percent.
In its first application, the inline-6 makes 395 horsepower
and 405 pound-feet of torque in the Range Rover Sport HST special edition,
which is 15 more hp than the previous 3.0-liter V-6 engine. Those numbers are
converted from the British figures, so the official U.S. numbers could differ.
The SUV clocks a 0-60 mph time of 5.9 seconds before topping out at 140 mph.
We're eager to see where the inline-6 engine ends up next,
and what its performance boundaries are. We can only imagine what JLR's Special
Vehicle Operations may have cooking. Land Rover did note, however, that there
will also be a 355-hp version of the engine.
The Range Rover Sport HST with the new engine starts at
81,250 Pounds, or about $104,500 at current exchange rates. Land Rover
spokesman Nathan Hoyt told Motor Authority U.S. pricing will be
announced in the coming days.
Buyers of the Range Rover Sport HST will also get a
carbon-fiber trimmed exterior, red brake calipers, special badges, and updated
color patterns for the interior. Satin Chrome gear shift paddles flank a
steering wheel trimmed in suede and HST badges are also present inside.
We'll likely see the official debut of the Land Rover Range
Rover Sport HST at the 2019 New York International Auto Show in April.
