G-Power tuned BMW M4 GTS whips up 458kW


With 368kW (493hp) boiling at 6250rpm and 600Nm on tap from 4000 to 5500rpm, the limited edition, $300k BMW M4 GTS track day special is already packing a heap of punch from the factory. But that didn’t stop German tuner G-Power from turning the whip up on the M4 GTS even more with a power boost and subtle cosmetic upgrade.

The 3.0-litre turbocharged straight-six engine scores an optimised engine mapping and uprated turbochargers with aerodynamically optimized turbine and compressor wheels which allow for higher boost pressure.


As a result the engine now pushes out a potent 458kW (615hp) of power and a colossal 760Nm of torque, enough to propel the track-oriented M4 GTS from zero to 100km/h in just 3.6 seconds (0.2 second quicker than stock), en route to a derestricted top speed of 320km/h.

Complementing the boost in performance, G-Power has equipped with M4 GTS with a set of bespoke 21-inch wheels and lowering springs for a properly aggressive stance.
