Following news of a four-door AMG GT variant, Mercedes-AMG appears to have released a teaser video showing quick flashes of the upcoming high performance four-door, and as usual with teasers, it refrains from showing the car in its entirety.

As seen on the video above, a clue to its powertrain lies in the ‘EQ Power+’ branding on what appears to be a front fender-mounted side rear-view camera. This indicates that the GT Concept will feature a certain level of drivetrain electrification. Mercedes-AMG said earlier the new brand will be the mark of future performance hybrid models, as heralded by the 2017 W08 EQ Power+ Formula 1 car.

The four-door GT Concept will depart from the use of the GT range’s standalone platform and will adopt the marque’s MRA architecture for longitudinal front-engined, rear-wheel drive cars. From these video stills, the concept car also appears to employ variable aero treatments on the front of the car, namely along the lower half of the front bumper, possibly also with active side intake shutters.

Certain design elements represent slight departure from the GT and GT Roadster norms: witness the more intricate wheel design and the different headlamp style. The rear lamp, though also a departure from current two-door GT design, is more familiar, while the four-door here also indicates use of a central exhaust outlet.

Exact powertrain details are yet to be confirmed, but the four-door GT Concept is thought to employ an integrated starter generator (ISG) housed within the transmission, for temporary boosts of up to 20 hp, drawn from a 48V electrical system and a lithium-ion battery.

On the internal combustion front, the now-familiar 4.0 litre twin-turbo petrol V8 should be used, with the more potent ‘S’ version possibly surpassing the E 63 S‘s 603 hp. Further along in the four-door GT’s lifecycle, Mercedes’s new turbocharged, 3.0 litre inline-six could also join the line-up.
