G-Power BMW M3 and M4 with 560 horsepower

G-Power releases a new upgrade to their tuning program for the BMW M3 and M4. G-Power has created its Bi-Tronik 2 V2 ECU remap for the twin-turbocharged 3.0-litre six-cylinder engine. Next, the tuning shop installed custom downpipes for an expensive titanium exhaust system with four 90 millimetre tailpipes. All these upgrades combined bring the total power output to 560 horsepower from the stock 425 and 720 Nm of torque at 4500 rpm. As a result, the G-Power BMW M3 and M4 will sprint to 100 km/h in a mere 3.8 seconds as well as a top speed of 310 km/h. A custom set of wheels was also specially created for this M3 and M4 project. The 21-inch Hurricane RR forged wheels are wrapped in 245/30 and 295/25 rubber and feature a twin-five spoke design.
