New 2018 Mercedes-AMG GT four-door: new wind tunnel shots reveal design

After releasing official "spy shots" of its new AMG GT four-door earlier this week, Mercedes-AMG has now displayed the new model undergoing wind tunnel testing.  The Porsche Panamera rival will make its production debut at the Geneva Motor Show next month. 

The car in the wind tunnel pictures sports a light camouflage, but the overall profile and shape is clear to see. Although cues such as the rear-end shape are taken from the AMG GT Coupe, the rest of the bodywork, including the low front-end, is bespoke to this model.

Although wrapped in the typical prototype camouflage, it"s clear that the overall profile of the test mule has been transferred from the Mercedes-AMG Concept unveiled at last year’s Geneva Motor Show. The long, low bonnet is retained from the concept, as are the slim side windows, thick side haunches and sloping roofline. The concept"s silver and gold wheels are replaced by traditional silver items here, hiding some serious-looking performance brakes.

Last year’s AMG GT Concept featured a distinct aerodynamic focus, with hidden cameras in place of exterior door mirrors and moving radiator shutters in the air intakes that divert air where required for maximum efficiency – like the AMG GT R. These features are likely to appear on the production model, too.

An official name for the production model has yet to be confirmed but it will be the first model to use the EQ Power+ branding, which indicates that it’s a performance hybrid, using a mix of petrol and electric power.

Power will come from AMG’s 4.0-litre twin-turbo V8, helped by an additional electric motor mated to Merc’s 4MATIC+ four-wheel-drive system. There’s no word on power output yet, but we expect north of 600bhp - as AMG says the 0-62mph time is less than three seconds.
