Famous German tuner G-Power is back into the spotlights with another daring project carried out on the high-end BMW M3 and M4, both models receiving a power package and a more aerodynamic body styling kit.

In order to make the M3 and M4 faster along the track, the technicians from G-Power have installed a plethora of mechanical bits on both models.

We are dealing here with the fitting of the Bi-Tronik 2 V3 module with bespoke control parameters, which works hand-in-hand with larger turbine, compressor CNC machined wheels, gas flow optimised housings, larger diameter exhaust downpipes without catalysts, or lightweight titanium exhaust system with carbon-fiber encased tailpipe.

All these add more power to the cars` stock 3.0-liter M TwinPower Turbo inline straight-six engine, which in normal parameters develops 430 horsepower and 550 Nm of torque.

Now, the BMW M3 and M4 are churning out an impressive 600 horsepower and 740 Nm of torque, taking the sprint from 0 to 100 km/h in just 3.7 seconds. The topping also stands at 320 km/h.

The performance is also possible thanks to the new body elements, such as the new suspension system with the G-Power GM4-RS adjustable coilover, RS front spoiler, CS front splitter, as well as the CS rear diffuser and the CS boot mounted spoiler for better aero cooling.
