BMW X6 M and X5 M officially released

[4wheelsonline]

The German carmaker announced finally the release of X6 M and X5 M, two cars which take the SUV to another level. Both of this car have more aggressive bodykit, like all other M models, which besides looking better, also help with the cars’ aerodynamics. The real interesting stuff about this cars, where BMW developed a 4.4 liter V8 which delivers 555 hp (408 kW) from 5,750-6,000 rpm and peak torque of 680 Nm (501 lb.-ft.) available between 1,500 and 5,650 rpm. The M TwinPower Turbo features a common exhaust emission manifold which joins both rows of cylinders and also BMW’s Twin Scroll Twin Turbo Technology. Unfortunately, BMW hasn’t released any details on the cars’ acceleration and top speed, but rumors say that the 0-100 km/h (62 mph) sprint is done in around 4.5 seconds and the top speed will probably be electronically limited at 250 km/h (155 mph).
