Mercedes-AMG added the E43 sport sedan a
couple of years ago to appeal to the buyer looking for a fast car but without
the flashiness and firm ride of something like the full-fat
E63.
Well, the boffins at AMG have now enhanced the car by adding
mild hybrid technology and in the process renamed it an E53. We first saw the
technology in the 2019 CLS53 and E53 Coupe and Cabriolet models from AMG, which
were unveiled in January at
the 2018 Detroit auto show.
AMG's 53 series all feature a new 3.0-liter
twin-turbocharged inline-6 with an electric compressor to build the boost at
low revs. Peak power of the system is a V-8-like 429 horsepower and 384
pound-feet of torque, but according to AMG your fuel economy will come in
roughly 20 percent better than a V-8. The output compares to the 396 hp and 384
lb-ft from the 3.0-liter twin-turbocharged V-6 of the outgoing E43.
The mild hybrid part of the equation comes in the form of an
electric motor-generator that replaces the starter motor and alternator
typically found on internal combustion cars. The motor-generator is powerful enough
to give you a boost of 21 hp and 184 lb-ft during high-load situations, like
sprinting off the line, but can't power the car on its own.
And under braking, the motor-generator recovers energy to
charge up a battery for later use, so there's no need to plug the car in for
charging. The rest of the drivetrain includes a nine-speed automatic and
all-wheel-drive system as standard.
AMG quotes a 0-62 mph time of 4.5 seconds and a governed top
speed of 155 mph.
The E53 also benefits from some minor visual touches. These
include the power bulges on the hood, the circular design for the four exhaust
tips, and a more pronounced rear diffuser. The car is also available with a set
of 20-inch light alloys.
AMG will offer both an E53 sedan and wagon, though it's
likely we'll only see the former in the United States. Availability hasn't been
announced but we should see the car here later this year as a 2019 model.
