Forget about the Tesla EV charging station in the background, this spyshot is about a supercar still running on petrol. No less than three prototypes of the next-generation AMG GT Coupe were caught in snowy northern Sweden while test drivers were on their lunch break. We’ve never seen a Porsche 911 rival with as little camouflage as we do now, suggesting the official reveal will be in a matter of months, if not weeks.
All three describe different versions of what will essentially be the Affalterbach coupe version of the new SL roadster. The yellow car appears to be an AMG GT 43 judging by the four-turn tailpipe. If our assumptions are correct, power is provided by a 2.0-liter four-cylinder engine with an F1-derived electric exhaust gas turbocharger. In the mechanically related SL43, it produces 381 horsepower (284 kilowatts) at 6,750 rpm and 354 pound-feet (480 Newton-meters) of torque starting at 3,250 rpm.
Next up is a green car with a charging port cover on the rear bumper, which reveals that it has a plug-in hybrid powertrain. That might carry over the PHEV setup from the new AMG C63. Yes, that means another four-cylinder version. It will also use the same M139 engine that was originally developed for the “45” compact car before getting a longitudinally mounted configuration for the larger AMG. In (takes a deep breath) Performance Mercedes-AMG C63 SE 2024, electrification setup produces 671 hp and 752 lb-ft (1,020 Nm).
As for the other green car, the one with the fixed rear spoiler, it looks like a V8. That could be the limited-run AMG GT 63 Edition 1 with 577 hp (430 kW) and 590 lb-ft (800 Nm) to mirror the SL63. We’ll remind you that there’s also a lesser V8-powered SL55 that drops to 469 hp (350 kW) and 516 lb-ft (700 Nm).
In all cases, the SL’s coupe sibling should be slightly lighter thanks to a fixed metal roof than an electric-folding soft top. Also, the GT is expected to remain a two-seater affair while the latest SL has a 2+2 layout. While the latter is all about comfort, the former should prioritize a more thrilling driving experience with a stiffer suspension and sharper steering.
Future additions will include a track-oriented version and a plug-in hybrid with the same drivetrain used in the GT 63 S E-Performance. That means the electrified V8 produces 831 hp and 1,084 lb-ft (1,470 Nm) of torque. Towards the end of the lifecycle, there may be another hardcore Black Series.
