New 2018 Mercedes-AMG GT 4-Door: specs and pics

From concept car to production model in one year: the Mercedes-AMG GT 4-Door Coupe has finally been revealed at the 2018 Geneva Motor Show.

Extending the AMG GT family to three models alongside the two-door Coupe and Roadster, the 4-Door Coupe is “the first four-door sports car from Affalterbach” to go on sale. The sibling resemblance from the front is striking, with the new model featuring the same long, low bonnet, vertically-slatted grille and three-part lower air intake.

Blistered wheelarches fill out the side profile, while the roofline slopes dramatically to the tailgate, which again looks very similar to the two-door version. There"s either a pop-up rear wing or a larger fixed wing on higher performance versions. Quad tailpipes housed in a rear diffuser also feature.

Unlike the two-door AMG GTs, Mercedes-AMG is launching the 4-Door with both turbocharged V8 and straight-six petrol engine options.

The V8 is the same 4.0-litre twin-turbo unit found in various AMG models, and in S form it produces 630bhp and 900Nm of torque. That’s enough to take the two-tonne four-door Coupe from 0-62mph in a claimed 3.2 seconds and on to a top speed of 196mph. The non-S version is also available, making 577bhp and 800Nm of torque. That car’s 0-62mph time is 3.4 seconds, and it hits 193mph.

Both variants put their power through a nine-speed automatic transmission and permanent four-wheel drive with a variable torque split. Initial economy figures claim both versions are capable of 25mpg and emit 256g/km of CO2.

An entry-level model, which is expected to arrive later in the car’s lifespan, will feature the in-line six-cylinder engine from the updated S-Class limo that produces 429bhp.

The cabin moves the game on from other AMG GTs, with Mercedes’ dual 12.3-inch infotainment system and instrument panel.

More upmarket touches, such as the LED backlighting and individual air vents, are taken from the firm’s most luxurious models, but the large centre console, with a central gearshift flanked by eight large switches, is a trademark of the AMG GT models.

Mercedes has moved the drive mode select function to buttons mounted on the steering wheel, alongside the loud exhaust mode button and a Porsche-like quick-response ‘S+’ performance toggle switch. Trim options include everything from quilted cream leather to a carbon and Alcantara theme.

Prices will be revealed when the 4-Door Coupe goes on sale in September, with UK cars arriving in dealers at the start of 2019.
