At G-Power, the last naturally-aspirated six-cylinder M3 experiences the power treatment it deserves in order to make the best possible use of its motorsports backbone.

The G-Power SK I “Sporty Drive” supercharger system develops a power output of 450 bhp / 331 kW. However, not only the performance but also the efficiency of the M-power unit is significantly increased. G-Power’s 25 year experience in manufacturing high-performance cars serves as the basis for this performance treatment.

The G-Power product range therefore stretches throughout lightweight wheels, coilover suspensions and exhaust systems, which – perfectly adapted for the job in question – let a car arise that pays a tribute to the M motorsports affiliation.

Thereby G-Power provides the M3 E46 with a sportive presence that cannot be reached by the basic car. After the G-Power treatment, the M3 E46 finally allows its driver the ultimate driving experience.

Centrifugal Clutch for G-POWER Supercharger Systems
110.M46.037HOptinal centrifugal clutch K05+ for G-POWER supercharger systeme

The centrifugal clutch disengages the supercharger form the belt drive in idle. When the engine reaches 1.500 rpm the centrifugal clutch contacts automatically the supercharger to the belt drive. The advantages of the supercharger system with centrifugal clutch are:
- no additional noise emission in idle
- no unneeded operation of the supercharger
- better efficiency of the supercharger system and therefore a reduced fuel consumption.
Price is only valid in combination with the order of a G-POWER supercharger system.
