While there have been various companies, both locally and abroad, tuning various versions of the previous M3/4 to unleash more power G-Power says it is the first to offer power upgrades to the latest generation of BMW’s M performance twins.
Check out our video review of the BMW M4 Competition at this link.
The G3M and G4M can be ramped up in increments starting at 442 kW, a 67 kW increase over the standard Competition variant. If that isn’t enough there is a GP-650 software upgrade and the exhaust system, which combine to deliver 478 kW from the twin-turbocharged six-cylinder engine.

For now the max on offer from G-Power is a 515 kW version that adds downpipes to the custom exhaust system and software remap. But the company isn’t stopping there, in time they plan to offer an engine that will feature upgraded turbochargers for a power peak north of 550 kW. G-Power says that all the current offerings can reach a top speed of 333 km/h.
Regardless of the power rating one can dress up your G3M or G4M with a set of custom G-Power Hurricane RR and Hurricane RS forged wheels. These are wrapped with 255/30 and 305/25 tyres. Other visual upgrades that will be available include a ‘Venturi’ carbon-fibre bonnet and GP-Dynamic rear wing, the latter adding real downforce to the rear axle. The replacement bonnet improves the ventilation of the engine compartment.
