G-Power has created the Bi-Tronik 5 V1 system for the two Ms working with the base 3.0 liter twin-turbocharged six-cylinder engine. From the standard 425 hp, the tuner managed to raise the power output to 520 hp between 5500 and 7300 rpm as well as 700 Nm of torque from 1850 and 5500 rpm. That torque increase represents a 150 Nm jump.
The G-Power BMW M3 and M4 can now sprint to 100 km/h in 3.9 seconds and to 200 km/h in 11.8 seconds. Additionally, the top speed has been increased to 325 km/h.
The company also offers their new G-Power 20” Hurricane RR forged wheels for 8,000 euros and a new height and pressure-adjustable coilover suspension for 2,427 euro.
The power kit will set customers back 3,358 euros.
