G Power has introduced their new tuning program for the Mercedes S63 AMG Coupe.

Starting under the hood, the twin-turbo 5.5-liter V8 engine has been equipped with an optimized ECU which enables it to produce 705 PS (518 kW) and 1,000 Nm (737 lb-ft) of torque - an increase of 120 PS (88 kW) and 100 Nm (74 lb-ft). Thanks to the extra oomph, the 4MATIC model can accelerate from 0-100 km/h in 3.8 seconds before hitting a top speed in excess of 330 km/h (205 mph).

Styling changes are relatively limited but the company offers 21-inch "Power Hurricane RR" forged aluminum wheels with Michelin tires.

Unfortunately, the modifications aren't cheap as the wheels cost €9,095 ($11,150) and the performance package retails for €6,898 ($8,455).
