Somewhat surprisingly, however, the four-door GT does not yet get the all-new MBUX user interface that debuted at the Consumer Electronics Show in January.
The GT 4-Door Coupe comes with 9-speed automatic and all-wheel drive.
Despite the increase in power, Mercedes-AMG is not meant to improve overall performance.
AMG's designers have done an excellent job of making sure the 4-door GT looks like a proper AMG. The 4-door coupe looks deadly, but the engine specs are going to be even deadlier. Called the AMG GT 4-Door - not the AMG GT4 like we expected - the new four-door marks a huge point for Mercedes' AMG spin-off. The 4.0-litre V8 biturbo engine will be offered in two states of tune. It can sprint from 0 to 62 miles per hour in 10.5 seconds. Its top speed will be 315 kmph. This baby will do the 0-100 kmph sprint in 3.4 seconds and can go up to 310 kmph. Further complicating things, the Four-Door Coupe had to maintain the rigid body structure that let the original grand tourer handle so well, whether on street or track.
As with the two-door GT the new 4-Door Coupe relies heavily on aerodynamics to improve both performance and fuel efficiency. The 53 with its 6-cylinder in-line and 63 with a V8 engines provide outputs ranging from 435 hp to 639 hp and allow completely new driving experiences. Using a turbocharger, an electric compressor and 48V mild-hybrid technology, the powerplant develops 435 hp, with an additional 22 hp and 250 Nm (184.4 lb-ft) of torque coming from an electric motor. Top speed is 196mph and 0-62 takes 3.2 seconds. Drift mode is also available as an option on the regular GT 63. Up to a speed of 100 kmph, the rear wheels turn in the opposite direction as opposed to the front wheels which allows the vehicle to have better turn-in and reduces the turning radius, thereby offering better stability. The auto can be exactly what you want it to be.
There's an abundance of contrasting topstitching, and other embellishments include a Burmester surround-sound system, diamond-shaped perforated seats, a microfiber roof liner and sun visors, and door sills that are illuminated with MB lettering.
"Up to a speed of 62 miles per hour, the rear wheels point in the opposite direction to the front wheels via two electric actuator motors".
Pricing isn't known yet, but if the GT Coupe starts at $113,000 and quickly climbs with each step up in the range, don't be surprised if the 4-Door GT gets a base price that flirts with $200,000.
The all-new Mercedes-Benz A-Class is now on sale, with prices starting from just £25,800 ($35,600) for the A 180 d SE. This one though has its sights set on the Aston Martin Rapide, Maserati Quattroporte, and Porsche Panamera in the fast luxury saloon segment.
