The Manhart Performance crew always delivers high performance and speed. Their MH4 550 was released quickly after the launch of the original M4, and we simply love it.
The first thing they did was retuning the 3.0-liter TwinTurbo straight-six engine. Numerous upgrades provide the car with 550 horsepower, 120 HP more than the stock M4. The torque figure was even more improved – it went from 550 Nm to 820 Nm. Change in sound closely follows the power change with the new exhaust system installed.
