For the first time, Mercedes-AMG in Affalterbach created the SL. The GT will essentially be a hard-top coupé version of that car, with which it will share the majority of its underpinnings.
Because of the considerable concealment used at this early level of testing, the visual modifications appear to be restricted to a more rakish rear roofline and a custom front grille treatment. Once it is publicly disclosed, it is conceivable that various wheel designs, paint colours, and option packs may be released.
The present GT is a two-seater, but the SL offers rear seats for the first time in several generations, and the Porsche 911 and Ferrari Roma also have a pair of child-sized buckets in the back, so AMG may decide to enlarge the interior. The inside of the GT appears to be similar to that of the SL in these photographs.
The GT, like the convertible, will most likely follow a similar model. Because of the adoption of an all-new aluminium platform, the engine and axles are situated lower in the chassis, which is supposed to increase transverse stiffness by 50%.
It’s unknown if the GT will adopt a four-wheel-drive arrangement like the SL, but it’ll almost certainly employ the same rear-wheel steering system, and the limited-slip differential might come standard.
The SL will employ the same twin-turbocharged 4.0-litre V8 engine as the two previously disclosed models, but tuned to produce 577hp and 590lb ft of torque, resulting in a 0-62mph time of less than 4.0 seconds and a peak speed nearing 200 mph.
Soon after, plug-in hybrid variations of the GT 63e will be available, employing a derivation of the 831bhp electrified V8 utilised in the AMG GT 4-Door Coupé PHEV.
More information on whether the hardtop vehicle would weigh significantly less than the 1970kg SL 63 is likely in the coming months as a launch date approaches.
