Mercedes-AMG has been caught working on the new generation of their GT sportscar which will become a sibling to the new SL Roadster. The Porsche 911 rival made its spy debut during testing in the Arctic Cycle looking quite similar to the existing AMG GT in terms of styling. Our spy photographers caught two different prototypes that look like the upcoming 55 and 63 V8-powered variants. The lightly camouflaged prototypes are wearing the production headlights and taillights sporting a familiar shape – especially at the front. The low-positioned Panamericana grille appears to be slightly larger, flanked by prominent AMG-style intakes on the short front overhang.

The proportions are typical of a front-engined rear-wheel-drive model while the bodywork is slightly more sculpted compared to its predecessor. The rear end has changed more than the face, with more modern horizontally-mounted LED taillights, an active rear spoiler, more pronounced rear shoulders, and quad exhaust pipes. What is different between the two variants is the shape of the exhaust outlets which are round in the 55 and squared in the 63, plus the different wheel/tire combinations.

 

Inside, we expect the new GT to inherit the latest MBUX infotainment technology featuring Mercedes’ new screen layout with an 11.9-inch touchscreen display in portrait mode covering most of the center console just like in the SL. The seating layout could be 2+2, offering more practicality on par with its rivals, or a strict two-seater to differentiate itself more from the SL roadster.

The composite aluminum platform will be shared with the SL, although the air suspension and the chassis setup will likely change supporting the GT’s more driver-focused character. Under the bonnet, we expect the twin-turbo 4.0-liter V8 in different power outputs. In the SL sibling, the 55 produces 470 hp and 700 Nm of torque, while the 63 produces 577 hp and 800 Nm of torque. Power will be transmitted to the rear axle through an automatic gearbox, although we’ll have to wait and see if AMG offers the GT with the 4Matic all-wheel-drive system. The range is set to expand in the future with lesser V6-powered variants and possibly a plug-in hybrid flagship producing up to 831 hp.

The Mercedes-AMG GT is expected to premiere sometime in 2023, although nothing is official with the German brand keeping their cards closed for now. This generation is going to be exclusively available in coupe bodystyle since it has been confirmed that the SL will take the role of the discontinued roadster.
