Performmaster Dials Up Mercedes-AMG GT 63 S To 730 HP

Right now, the Mercedes-AMG GT 63 S is hands down one of the coolest, and fastest, four-door cars money can buy.

That doesn’t mean it can’t be improved, though, and that’s exactly what German tuning firm Performmaster is trying to achieve with its GT 63 S “1of31” limited edition project based on AMG’s finest four-door car.

The name says it all, really: only 31 of these souped-up AMG GT 63 S 4-Door Coupes will be made as a celebration of the aftermarket company’s 31st anniversary. Each receives identical styling and performance tweaks. Yes, the folks from Performmaster wanted to improve on the standard AMG GT 63 S 4 Door Coupe’s 639 PS (630 hp) and 900 Nm (664 lb-ft) of torque produced by the 4.0-liter twin-turbo V8.

So they pushed it to 740 PS (730 hp) and 1,030 Nm (760 lb-ft) courtesy of the PEC Tuning Module that connects directly to the AMG engine control unit. Mated to the same nine-speed automatic transmission and 4Matic+ AWD system, the tuned engine allows the sleek four-door coupe to sprint from 0 to 100 km/h in 2.9 seconds, making it 0.3 seconds quicker than the stock car. The top speed remains unchanged at 315 km/h (196 mph).

The phenomenal performance is accompanied by a custom aerodynamic package consisting of handcrafted carbon fiber parts including a front splitter, rear wing and diffuser painted either in body color or in high gloss black. Mounted on the original attachment points, the wing is said to improve stability and handling at high speeds on straights and in corners, while Performmaster also offers a lowered adjustable suspension that’s supposed to “noticeably” improve handling and driving dynamics.

Finally, the interior gets only subtle “1of31” applications to remind passengers they’re not just in any GT 63 S, but in a limited edition.

    Doesn’t change the fact that it hit every branch down the ugly tree.

      You probably haven’t seen this car in person. It looks much better than on the pictures.

        It really doesn’t.
        The front looks almost decent, but the rear end is a disaster.

        Funny you should say that. I HAVE seen this car in person. To me it’s actually worse in person lol.

        This car has no saving grace.

    Yea, this isn’t newsworthy.
