Geneva Motor Show 2018: Mercedes-Benz launches family-friendly AMG GT 4-Door Coupe

Mercedes-Benz has unveiled its first ever four-door supercar at the Geneva Motor Show 2018. The new AMG GT 4-Door Coupe has a top speed of 195mph and will start in the region of £110,000 when it goes on sale in the summer.

Part of the AMG GT supercar range, the AMG GT 4-Door Coupe promises to add some family-friendly practicality and limo-like luxury to the otherwise uncomfortable and cramped world of supercars. Available with turbocharged V6 or V8 engines, with 435PS - 639PS, the GT 4-Door Coupe will be capable of covering 0-62mph in just 3.2 seconds.

Despite the supercar connotations the AMG GT 4-Door Coupe has more in common with the CLS than the two-seater GT car, with a similar swoopy exterior profile that should provide enough interior space and storage for four adults to travel in comfort. The boot capacity is a modest 395 litres, while passengers sitting in the rear get an Audi A8-style touchpad screen to control heating, lighting and seating adjustments.

The interior uses the same panoramic design as the E-Class, with a wide windscreen and sweeping dashboard that's dominated by a pair of 12.3-inch HD screens. The digital instrument binnacle can be configured with different themes – classic, sport and supersport – allowing the driver to add details on torque, traction, engine data and g-force. Superport mode also features an F1-style gearshift light indicator for track driving.

The AMG GT 4-Door Coupe should be capable on the road too; all get four-wheel drive and race-tuned nine-speed automatic gearboxes as standard, along with an electronically controlled locking rear differential that promises improved grip by pushing the surface of the tyre flat as you accelerate out of a bend.

The entry-level AMG GT 53 4Matic+ is the only model to use a V6 engine, but uses a hybrid system to boost performance. Developing 435PS and covering 0-62mph in 4.5 seconds, it’ll be sufficient for most buyers who want a luxurious and capable coupe, while claimed economy will be 31mpg and 209g/km of CO2.

Alongside the 3.0-litre V6 are two 4.0-litre biturbo V8s. The AMG GT 63 4Matic+provides 585PS and a blistering 3.4 second 0-62mph time. The AMG GT 63 S4Matic+ ups the power stakes to 639PS and shaves 0.2 seconds off the 0-62mph sprint. Both will return roughly 25mpg and 252-256g/km of CO2.

Depending on the engine, there are up to six drive programs to choose: slippery, comfort, sport,  sport+, race and individual. Selectable via the gearshift paddles, the settings sharpen the handling, gearbox and throttle responses. The suspension and traction control can also be tailored to match track requirements.
