Mercedes Benz 2016 Amg Gt |
The 2016 Mercedes-AMG GT is an
all-new model, but comparisons between it and the outgoing SLS AMG GT will
undoubtedly be made. It's now time to say goodbye to the SLS GT's memorable and
flashy gullwing doors, along with its burly and rowdy-sounding 6.2-liter V-8.
The Mercedes-AMG GT also packs an eight-cylinder, but it's a smaller
displacement mill that's sporting two turbos. You'll also notice the new car's
spiffy name (no "Benz") that the automaker says is a preview of
naming changes for upcoming AMG products. We'll report on that name game at a
later date. For now let's focus on the AMG GT, which is the second car to be
completely designed and developed by the folks at Affalterbach. Like other recently launched AMG models, the Mercedes-AMG GT
will be offered in a base and an S model. Both are powered by an all-new
4.0-liter, twin-turbo V-8 that makes 456 hp and 443 lb-ft of torque in the base
GT and 503 hp and 479 lb-ft in the GT S. This engine, which was developed
specifically for the GT and is also referred to as the M178, showcases a
special turbo setup dubbed "hot inside V." Here, the two
turbochargers sit within the engine's V configuration, as opposed to the
typical layout, in which the turbos are placed outside of the cylinder banks.
This setup gives the M178 its compact dimensions.

Coupling that with the M178's dry sump lubrication system allowed engineers to mount the engine low in the bay, improving the GT's center of gravity.

Those turbos also give the M178
a fat torque curve. For starters, max torque in the GT arrives at just 1600 rpm
and 1750 rpm for the GT S (peak horsepower is around 6000 rpm for both). For
comparison, the M159, 6.2-liter, naturally aspirated V-8 (583 hp and 479 lb-ft)
that powered the SLS AMG GT spun at 4750 and 6800 rpm to reach max torque and
horsepower, respectively. We've praised the M159 for its linear power delivery,
and AMG is promising the same from the M178. Like the SLS, the Mercedes-AMG GT
is fitted with a seven-speed dual-clutch transmission in a rear transaxle
setup. Mercedes says the GT's gearbox is improved with a larger gear ratio
spread and quicker shift times. That said, the Mercedes-AMG GT is estimated to
run from 0 to 60 mph in 3.9 seconds, with the GT S a few ticks quicker at 3.7
seconds. Top speed for the GT and GT S is 189 and 193 mph, respectively. AMG's new sports car will be the first model to be offered
with the AMG Dynamic Plus package. This package, which is exclusive to the GT
S, consists of variable engine and transmission mounts. The system essentially
softens the mounts during relaxed driving and stiffens them when it comes time
to tear through canyons or the track. The AMG Dynamic Plus package also
includes a stiffer suspension setup, more negative camber at the front axle,
and revised steering. Out back, the GT S features an electronically controlled
rear-axle locking differential, while the GT is fitted with a mechanical
locking diff.
