If you believe that the stock BMW X6 M is underpowered, then you should take a look at Manhart’s tuning packag.
The 4.4-liter V8 biturbo engine was lifted from 575 PS (567 HP) and 750 Nm (553 lb-ft) of torque to no less than 700 PS (690 HP) and 950 Nm (701 lb-ft) of torque. The extra oomph came after the tuner remapped the ECU and fitted an aftermarket exhaust system with modified silencer and new downpipes.
Manhart wasn’t keen on releasing any performance specs on its BMW X6 M, which was renamed as MHX6 700, but it should be considerably faster over the standard model’s 4.2 seconds for the 0 to 100 km/h (62 mph).
Having received a power bump and a new name, mods made to the range-topper X6 continued on its exterior too, where Manhart added a new carbon fiber bonnet and 22-inch Concave One wheels, available in black or silver. Inside, the tuner added yellow accents on the steering wheel, center console, dashboard and door panels. All upgrades are also compatible with the BMW X5 M, but no pricing details were announced so far.
