Mercedes-AMG GT 4-door Coupe: Geneva Auto Show

The all-new Mercedes-AMG GT 4-door Coupe has been revealed, with the performance-oriented rival to the Porsche Panamera carving its own niche in the realm of 4-door AMG models.

Set to slot between the Mercedes-AMG E 63 S and Mercedes-AMG S 63 models, the new 4-door version of the GT sports car is no limousine like its sibling sedan models: In fact, Mercedes claims the new model "combines the impressive racetrack dynamism of our 2-door sports cars with a high level of day-to-day suitability".

The all-new GT 4-door Coupe model is expected to arrive in U.S. showrooms in late 2018 or early 2019, and of course it will sit above the all-new CLS 4-door "coupe." The simplest way to look at it is this -- the CLS is now the luxury-focused model, whereas the GT 4-door is a more hardcore plaything.

As a result, the 4-door "fastback" model is destined to be offered with a potent 4.0-liter twin-turbocharged V8 engine producing as much as 639 horsepower at 5500-6500 rpm and peak torque of 664 lb-ft at 2500-4500 rpm.

Those are the outputs for the Mercedes-AMG GT 63 S 4Matic+ model. As you may be able to tell from its name, the 4Matic+ bit means there's an advanced all-wheel-drive system with a variable torque-split function and drift mode. Shifting gears is a 9-speed sports automatic transmission.

Mercedes-AMG claims the GT 63 S model will sprint from zero to 62 mph in a Porsche Panamera Turbo-smashing 3.2 seconds, on its way to a 196-mph top speed. The performance on offer is the more impressive considering the AMG GT 63 S model weighs in at 4,674 pounds (curb weight).

Another model in the range is the slightly less manic Mercedes-AMG GT 63 4Matic+ -- note there's no "S" in this moniker, which means a little less performance. The GT 63 uses the same drivetrain as the GT 63 S, but with 585 hp at 5500-6500 rpm and 590 lb-ft of torque from 2350-5000 rpm.

The non-S GT 63 model will cover the sprint from zero to 62 mph in 3.4 seconds, and its top speed is 193 mph.

The third drivetrain that will be offered internationally in the GT 4-door Coupe is that of the GT 53 4Matic+ variant: a 3.0-liter 6-cylinder turbo with an additional electric turbo and onboard 48-volt electric mild-hybrid system.

It's the same system used in the CLS 53 model, with peak engine outputs of 435 hp at 6100 rpm and 384 lb-ft of torque from 1800-5800 rpm, plus the additional EQ Boost system, which gives an extra 22 hp and 184 lb-ft when needed. The system can also allow advanced brake energy recuperation, and will allow the car to cut the engine while coasting. It doesn't directly power the wheels in any way, though -- it just supplements what's already there.

Inside the GT 4-door Coupe, there are some elements we've come to expect from the Benz group, including a broad, bold pair of 12.3-inch screens, and lashings of leather and carbon fiber.

But the new GT 4-door Coupe also brings a completely rethought center console control area, with eight miniature screens that control an array of different systems, including the media system and the settings of the car's suspension and drive modes. There are even two color mini screens on the steering wheel -- one for adjusting the drive mode, and another with two "favorites" settings you can toggle between.

There's also a new touchpad media interface, rather than the rotary-dial Comand system we've seen in every modern-era Benz to this point. It's the same as is set to be offered in the new A-Class. The shift indicator is located near the gear selector -- and you'd be forgiven for thinking that there are several "I" modes between "P", "R", "N" and "D", even though there aren't.

Clear from the images is the fact that AMG will offer a luxury-focused interior package with tan and silver trim finishes alongside the carbon-clad version, with style highlights such as the Affalterbach seal embossed on the seat headrests, a central console that runs from the dash to between the rear seats, and multiple ambient-lighting elements.

There will also be a rear control screen for back-seat passengers to change the media playback, lighting and other elements of the cabin environment. But if that gets annoying, the driver can lock the screen by hitting the window-lock button on their door. Neat!

It's understood the standard GT 4-door will come with five seats, with a 4-seat layout offered for those who know they'll never actually subject someone to that middle spot.

Full specifications and pricing will be announced for the Mercedes-AMG GT 4-door Coupe closer to its local launch.
