Mercedes-AMG GT 4-Door Coupe Gets a 731 HP Tune
This model represents 31 years of Performmaster tweaking AMG cars, so you know it's going to be special.
Long Title
The name of this car is a bit of a mouthful. It's the 'Performmaster Mercedes-AMG GT 63 S 4-door Coupe 1 of 31 Limited Customer Edition'. This model is stunning both visually and in terms of its performance but, as its name suggests, it's rare. With just 31 of these cars hitting the roads, you'd be lucky to ever see one up close.

Horsepower
The standard 2019 Mercedes-AMG GT 63 S puts out a not-too-shabby 631 horsepower. But nothing that goes into Performmaster comes out producing the same numbers. This model now has an eye-watering 731 horsepower. Surprisingly, no major overhaul was necessary to add the extra 100 horsepower. The AMG specialists at Performmaster just needed to get their hands on the PEC tuning module and tweak it.

Torque
Squeezing out an extra 100 horsepower is no small feat but the amount of torque this model produces is equally if not more impressive. The standard AMG GT 63 S pumps out 664 lb.-ft of torque as standard, but this model produces a stomping 760 lb.-ft. Needless to say, this car shifts.

Acceleration
All those horses and, more importantly, all the extra torque is going to push up this car's performance figures. The standard model will get to 62 mph from a standstill in just 3.1 seconds. Clearly, there's not a whole lot to improve upon but the specialists at Performmaster managed to shave off 0.2 seconds: 62 mph shows up in just 2.9 seconds.

Unchanged
There are still a few things that remain unchanged about AMG GT 63 S. The top speed, for example, still sits at 196 mph and that is plenty fast if we're being honest. And its curb weight is still over two tons which undoubtedly helps when trying to transfer all of the car's torque to the road. It also uses the same 4.0-liter twin-turbo V8 engine.

Just 31
Unfortunately, Performmaster is only going to produce 31 of these models. This may seem like an arbitrary number, but it's not. Performmaster has been tuning AMG cars for 31 years and wanted to honor this fact.

Subtle Changes
Although the most impactful changes to the AMG GT 63 S lie beneath its skin, it did receive some alterations to its body. This model has a front splitter, slightly bigger rear wing, and a rear diffuser. These changes are subtle but an enthusiast will quickly be able to tell this apart from the standard model.
