Polish tuner MM-Performance recently finished upgrading a BMW X6M with a Chip Power Box from the famous BMW tuner Hartge. This treatment gives the E71-series X6 a fresh breathe of life in form of an extra 68 horsepower and 90 Nm of torque.
The Hartge electronic kit fitted to MM-Performance BMW X6M increases the standard dyno’d 516 hp and 664 Nm up to 584 hp and 755 Nm of torque.
They haven’t measured the performance, but that is a huge gain in power – especially as it’s been achieved through electronics and air filters only – and ought to have a profound effect on the car’s acceleration, top speed, and general responsiveness.
Visually, MM-Performance BMW X6M features a juicy red paint job with matching aero parts including a fairly prominent decklid spoiler, plus blacked-out grilles, tinted windows, and smoked lights. The car also has a set of black wheels with red accents which look pretty cool.
