The upcoming four-door member of Mercedes-AMG’s new GT family, previewed to the world earlier this year as the GT Concept, has been spotted doing a couple of laps at the Nurburgring Nordschleife.
The heavily-camouflaged prototype keeps much of its details hidden, but visible is the illumination signature of its narrow-slit headlights and side mirrors rising from the door sheet metal – a design cue which Mercedes reserves for cars with a coupe positioning.
From the side, the Concept’s Panamera-rivalling fastback silhouette is visible, albeit distorted by protrusions tacked over the bootlid. Frameless doors are obvious.
More is revealed at the rear end, where we get to see the outline of the tail lights, bumper-mounted license plate, and quad exhausts.
Early technical info released by Mercedes describes this as another independently-developed vehicle by AMG. Its bodyshape is unique within the Mercedes family, though it is not clear if its underpinning platform is similarly unique or based off another model.
A high-performance petrol-electric hybrid powertrain, pairing AMG’s 4.0-litre bi-turbo V8 with an F1-based electric drive, is expected to produce outputs in the region of 805hp, enabling the four-door GT to race from 0 to 100km/h in less than three seconds.
