Official: Mercedes-AMG GT and C63 by Posaidon

Aftermarket tuner Posaidon has just unveiled its tuning upgrades for both the Mercedes-AMG GT and the new Mercedes-AMG C63 and C63 S. As both cars utilise virtually the same twin-turbocharged 4.0-litre V8 engine, it is little surprise the same upgrades apply for both performance cars.
Typically, the Mercedes-AMG GT and AMG GT S models deliver 462 hp and 510 hp respectively with torque sitting at 600 Nm and then 650 Nm. The Posaidon upgrades lift peak power to 630 hp while torque rises to 725 Nm. Consequently, the Posaidon powered Mercedes-AMG GT powered models are capable of hitting 337 km/h.

As for the Mercedes-AMG C63, it typically produces 476 hp and 650 Nm while the C63 S lifts those figures to 510 hp and 700 Nm. Following the tuner’s upgrades however, horsepower rises to 610 with 800 torques also on tap. As a result, the cars will peak out at a 328 km/h top speed.

The aforementioned power and torque upgrades achieved for the Mercedes-AMG GT and Mercedes-AMG C63 models are all achieved through simply re-programming of the engine’s control unit. Further down the road, Posaidon will offer upgraded turbochargers as well as a number of free-flow exhaust systems and other hardware modifications.
