When the BMW M4 leaves the factory, its 3.0-liter twin-turbo six-cylinder engine delivers 425 hp and 550 Nm of torque. It’s fast.

Nevertheless, famed tuning company G-Power has worked its magic on the two-door sports car, lifting power to 680 PS and 760 Nm of twisting force, enough to send the car to 100 km/h in just 3.5 seconds and through to a 330 km/h top speed.


These gains have been achieved through a host of modifications, which include custom turbochargers that incorporate a new turbine and curved turbine blades. A lightweight titanium exhaust system has been fitted and coupled with 90 mm carbon tailpipes. Last but not least among the mods, is G-Power’s new Bi-Tronik 2 V4 ECU remap.

G-Power offers the M4 with a set of bespoke coilovers with adjustable shock absorbers. Hurricane RR forged wheels measuring 21x9 and 21x10.5 then complete what is surely one of the market’s most well-rounded M4 packages.
