Renowned tuning shop G-Power has just revealed its power packages for the 2015 BMW M3 and BMW M4.

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.
