VIDEO: BMW X6M 555HP V8 Turbo on the Race Track

Here's some new video footage of BMW's M-badged X6 SAV on the race track. Like its X5M twin, the X6M comes with a new 4.4-liter twin - turbo V8 engine delivering a maximum output of 555 horsepower and a peak torque of 680Nm or 501-lbs/ft. Power is distributed to all four wheels through a six-speed automatic transmission with the Bavarian firm claiming that it's high-performance crossover accelerates from zero to 100km/h (62mph) in just 4.7 seconds.

New BMW X6 xDrive35i and xDrive50i M Sport Packages Include Significant Power Upgrades

This fall will see the introduction of a new M Sport package for the BMW X6 xDrive35i and xDrive50i turbocharged gasoline models. What's interesting about this package is that, unlike other M Division kits that comprise mainly of styling upgrades and quite often slightly more aggressively tuned suspension and different wheels and tires, this one actually adds much in the way of performance.

More specifically, the M Sport Package sees the X6 xDrive35i gaining the same tweaked version of the 3.0-liter twin-turbocharged inline-six found on the 740i that produces 326HP at 5,800 rpm and 450Nm of peak torque from 1,500 to 4,500 rpm. That's an additional 20HP and 50Nm of torque compared to the standard X6 xDrive35i.

The X6 xDrive50i (damn those marketing folks at BMW and their over-complicated naming systems...) gets an even greater power boost as the 4.4-liter twin-turbo V8's output is lifted from 408HP to 446HP. In comparison, the new X6 M model's 4.4L V8 turbo makes 555 horsepower.

If we translated the German press release correctly (if not, we'll be much obliged if our German readers could take a look at it below and make any necessary corrections or/and additions), the M Sport Package for the X6 SAVs will also include a body kit, 20-inch alloy wheels and a sportier interior trim.

For the record, the vehicle pictured above is the 555HP X6 M variant as the Bavarian automaker did not disclose any photographs of the X6 with the M Sport Package.
