Mercedes-AMG GT 63S vs Porsche Panamera Turbo S: The 4-Door Supercars Finally Meet

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.

    Pretty funny what is considered a supercar these days

    • Adi

      What else would you call a car with this level of performance? They have better 0-60 time than an Enzo.

      • TheAmerican2point0

        A car from 16 years ago

        • nastinupe

          They a 0 – 60 time that can challenge a Pagani Huayra. What about that?

          • TheAmerican2point0

            Sure, but does that make the Dodge Demon a supercar?

  • carsmofo

    anyone else finds the AMG GT severely unattractive? I really dislike Mercedes’ current design language.

    • Kagan

      I agree but that goes for most cars today.

      I think it looks toufer than Panamera.

      Either way they mostly have no rear passangers so you better get a 911 or something.

      I’m a Mercedes-Benz Fanboy through and through…

      I like the front quite a bit. And I’ve gotten used to the Pan-American grille, or whatever it’s called. The car looks fine from the sides. I’m not so sure about the back of the car. It just doesn’t look resolved.

      I’m also not a fan of the asymmetric D pillars.

      • europeon

        The panamericana grille is actually the best thing that happened to the current Mercedes design language, and it makes the front looks really good, but the rear… it’s a mess IMO. I can’t think of a Mercedes car from the past years that has a visually pleasing rear. The coupes with the horizontal slant-like taillights look like grafted from anothe car, the big sedans look extremely generic, the small sedans look too busy, and, on top of that fake exhaust vents and needles aero elements make it even worse.

    • paulgdeaton

      I agree – and I find the Panamera equally unattractive. The Mercedes looks like to designers tried for a “brutish” look, like an ill-proportioned bulldog, while the Panamera… graft a Porsche-like front end to a bulbous sedan body… and take a break.

      Neither is a design worthy of their price – or of their heritage – but they will both sell like hotcakes.

    Panamera is more elegant, the MB looks garish inside and out. The MB makes the right noises though, a big factor in performance cars for me. That said, neither of these appeals to me. Why not save and just get something awesome like a Quadrifoglio, an M5, etc.?
