The Mercedes-AMG GT 63 S has been blowing people’s minds from the moment it was released – and this particular example is even more special than most.

That’s because, whereas a standard GT 63 S features a 4.0-liter twin-turbocharged V8 with 630 hp and 664 lb-ft (900 Nm) of torque, this one has even more.

The company responsible for this modified GT 63 S is called Performmaster. Thanks to the inclusion of the PEC Tuning Module which directly connects to the AMG engine control unit, the car now produces 730 hp and 760 lb-ft (1030 Nm) of torque. Sport Auto recently had the opportunity to test the car.

During its test, Sport Auto was able to launch the car to 100 km/h (62 mph) in 3 seconds flat, just 0.1 seconds off Performmaster’s claim, and 200 km/h (124 mph) in 9.9 seconds, a time which is perhaps even more impressive than the first one. The run was recorded on a race circuit and, if done on a prepped drag strip, even lower numbers might have been achieved.

Performmaster didn’t called it a day after installing the power module into the GT 63 S, though, but adorned the super saloon with a bespoke aerodynamic package which includes a front splitter, rear wing, and a rear diffuser, while customers can also opt for a lowered adjustable suspension. Only 31 units of the tuner’s GT 63 S performance package will be produced to celebrate its 31st anniversary.
