G-POWER, the specialist for charging technology for years, expands its product range with AMG models. The power increase of the charged AMG models is far from being new for G-POWER. For many years, loyal customers who have an AMG in the garage in addition to a high-power BMW, have received power-technical upgrades for their vehicle from Affalterbach. Since the number of these modifications grew continually, it was only consistent that this know-how was made accessible to a wider audience.The focus of G-POWER, as in the BMW models, remains on the most sporty versions with the star – the vehicles by AMG. The beginnings were made by the AMG models with the strong 5.5 litres V8 biturbo motor, which will in future be supported by the G-POWER AMG division.

Key Facts: G-POWER S63 Coupé C217

705 PS / 518 kW at 5,250 rpm (+120 PS / 88 kW) 1,000 Nm at 2,250 rpm (+100 Nm) V-max: >330 km/h 0-100 km/h: 3.8s (4MATIC-version) External power module Bi-Tronik 5 incl. V-Max lift for 6,898.00 Euro gross 21-inch forged wheel set HURRICANE RR incl. tyres, starting at 9,095.00 Euro gross (VA 9×21 inches, HA 10.5×21 inches)

The Bi-Tronik 5 V1-additional module, connected upstream of the original motor controller, which is used in the S63 AMG Coupé, records the information measured and submitted by the vehicle sensors before they reach the serial controller. The read-in data are modified by the microprocessor of the Bi-Tronik 5 and thus submitted to the serial controller which then determines the parameters responsible for the output, such as fuel quantity and ignition time, also initiating a moderate increase of the charge pressure. The result gives the 5.5 litres V8-Biturbo drive of the S63 AMG Coupé a power increase of 585 PS (430 kW) / 900 Nm to 705 PS (518 kW) / 1,000 Nm, giving the S63 AMG Coupé a noticeably more powerful performance characteristic.

After the power treatment, 100 km/h are reached after only 3.8 seconds, with the acceleration orgy only ending beyond the 330 km/h.

Of course, the G-POWER technicians also considered compatibility of the motor hardware in their power upgrade: in the external G-POWER Bi-Tronik 5 V1 power module, all motor protection and diagnosis functions are retained. For example, the power increase is only activated when the prescribed cooling water temperature is achieved, and temporarily switched off when a maximum permitted oil temperature is reached – e.g. when driving under permanent full load in high summer.

On the chassis side, the observer will notice the ultra-light-weight 21-inch G-POWER HURRICANE RR forged wheel set of high-tech aeroplane aluminium, equipped with tyres from G-POWER technology partner MICHELIN in 265/30R21 on the front axle and 295/30R21 in the rear. With their double-spoke design, the G-POWER wheels set individual accents at the body of the S63 AMG Coupé, raising it from the masses.  

The costs for this power upgrade are more moderate than the offered additional power suggests: 6,898.00 Euro gross for the external Bi-Tronik 5 power module incl. the manipulation of the serial electronics to raise the V-max limit. The G-POWER forged wheel set HURRICANE RR incl. MICHELIN tyres is 9,095.00 Euro gross.
