2018 Geneva Motor Show: Mercedes-AMG debuts GT 4-Door Coupe

By David Undercoffler | March 6, 2018

After decades of breathing ferocious power into various Mercedes-Benz vehicles, the brand’s AMG division finally has a four-door model to call its own: the GT 4-Door Coupe.

This new car -- unimaginative name and all -- joins the two-door AMG GT Coupe and convertible as the only standalone cars under the AMG sub-brand that have no counterpart at the larger Mercedes brand.

It debuted Tuesday morning at the 2018 Geneva Motor Show in Switzerland.

Based loosely on the Mercedes E-Class and CLS, the AMG GT 4-Door will offer a trio of performance-oriented powertrains.

At the top of the AMG GT 4-Door Coupe lineup is the GT 63 S, with a 4.0-liter twin-turbocharged V8 that’s good for 630 horsepower and 627 pound-feet of torque. It will do 0-60 mph in 3.1 seconds, Mercedes says.

A slightly less fierce version will also have the V8: the GT 63 (no S). It offers 577 horsepower and 553 pound-feet of torque and will do 0-60 mph in 3.3 seconds.

Both of these V8 models come with a nine-speed automatic transmission and all-wheel drive.

Bringing up the rear -- but no less impressive -- will be the GT 53. It’s considered a “mild hybrid,” thanks to a combination of a 429-horsepower, 3.0-liter turbocharged inline six-cylinder engine and a small electric motor that drivers can call on for quick bursts of power.

It can do 0-60 mph in 4.4 seconds and, like its V8 brethren, comes with a nine-speed automatic transmission and all-wheel drive.

Mercedes-AMG also strapped a variety of performance-enhancing goodies to the various GT 4-Door models, including optional carbon-ceramic brakes, an active rear spoiler, a drift mode, rear-wheel steering and dual 12.3-inch display screens in the dashboard with configurable displays.

The AMG GT 63 and 63 S are due on sale in early 2019; the AMG GT 53 arrives in the middle of 2019. Pricing hasn’t been announced yet.
