BMW X6M is one of the fastest vehicles on the road. Powered by the staggering 4.4 liter twin-turbo V8, which deliver 555PS and 678Nm of torque (500 lb-ft).  The Sports Activity Coupe (SAC) reaches 275 km/h (170 mph) and accelerates from 0 to 100 km/h in 4.7 seconds, which suits to a sports car, not to a 2.4 ton vehicle.

Manhart Racing offers performance package for X6M, which includes ECU remap and new calibrations for the new stainless steel exhaust system with four 90 mm tailpipes and two 200-cell HJS racing catalytic converters.

The result is 687PS, which is too much even for 2380 kg vehicle. The power-to-weight ration is now 3.4 kg/hp. The top speed rose to 319 km/h (198 mph), but the acceleration to 100 km/h is again 4.7 seconds, probably for 100 to 200 is a lot faster.

BMW X6M was extraordinary car before the tuning from Manhart Racing, but after that is just astonishing.
