G-Power Upgrades BMW M3/M4 to 520 Horsepower; Supplies Sexy New Wheels
Always rely on these guys to deliver something tasty for BMW's M cars. M3 owners have long seen G-Power as the go-to tuning company when more power is needed.
For its latest engine upgrade, the German outfit has tweaked the S55 powerplant to deliver 520 hp and 516 lb-ft of torque, thanks to its Bi-Tronik 5 V1 system. As a result, the modified 3.0-liter twin-turbo straight-six helps the hi-po sedan/coupe reach a top speed of 326 km/h.
The BMW M4 can now sprint to 100 km/h in 3.9 seconds, and to 200 km/h in 11.8 seconds. Other upgrades include a set of Hurricane RR alloys, available from 20-23 inches in size, and a new adjustable coilover suspension.
