PP-Performance and Fostla.de showed us an exquisitely tuned Audi safety car exactly three days ago. Now the tuners at PP-Performance have prepared something, which has impressed us very much again. This time they did not modify only one car, but under their customization were two Mercedes-AMG beauties. The first one is C63 S and the second – even better, the GT S model. There is nothing much done here, except for the breath-taking work on the engine.

By the way, the engine under the hood of both cars is Mercedes-Benz 4.0 liters V8 biturbo unit. And we must also remind you that this powertrain is actually AMG's variant. However, the specialists at PP-Performance weren't that happy with the output, so let's see what they have managed to achieve.

The top speed has been production limited to 250 kmph (155mph), while the sprint form 0 to 100 km/h has been estimated 4.0 seconds.
