The time has come to find out how the new Mercedes-AMG GT 63S 4-Door measures up against the ridiculously quick Porsche Panamera Turbo S E-Hybrid.
The two competitors take different directions as far as powertrains are concerned, but the end result is surprisingly similar despite the obvious power advantage of the Porsche.
That’s because the complex plug-in hybrid powertrain adds more weight on the Panamera, which has to carry around an electric motor, battery pack and other hardware. Porsche’s system pairs a 542hp 4.0-liter twin-turbo V8 with a 134hp electric motor for a combined 671hp (680PS) and 627lb-ft (850Nm) of torque.
The 0-62mph (0-100km/h) sprint takes just 3.4 seconds, while top speed is 192mph (310km/h). That’s supercar performance coming from something that tips the scales at 2,310kg (5,092lbs).
The Mercedes-AMG GT 63S, on the other hand, relies on a 4.0-liter twin-turbo V8 only for its motivation, but thankfully it’s one that produces 630hp (638PS) and 663lb-ft (900Nm) of torque – and the sound of a thunderstorm.
According to Mercedes, 0-62mph (0-100km/h) takes 3.2 seconds, while flat out it’ll do 195mph (315km/h). The figures appear better than the Panamera Turbo S, but that’s also thanks to the lighter weight of the AMG GT 63 S, which comes at 2.1 tonnes (4,629lbs).
So which one of these two super four-door GTs is the best? Autocar tries to find out on the video that follows.
