The new BMW X5 M and X6 M are finally revealed at the 2014 Los Angeles Auto Show, now, with even more power, extra gears and a host of other technological updates with them.
Their engine is a version of the twin-turbocharged 4.4-liter V-8 found in several other M cars, producing 567 horsepower and 750 nm of torque. That peak torque is produced from as low as 2,200 rpm, helping the vehicles accelerate from 0-60 mph in 4.0 seconds flat with launch control activated. Top speed is limited to 250km/h.
M engineers also worked over the suspension. Modified upper wishbones are used too, which are said to have an increase in camber as well as optimized camber progression and steering pivot axis to aid agility in corners. BMW xDrive all-wheel drive is standard, but with a rear-biased torque split unique to these M variants. The system employs an electronically controlled multi-plate clutch to allow fully variable distribution of drive between the front and rear axles—from 100 percent at the rear to up to 100 percent at the front.
The stock wheels are 21-inch light alloys and the tires are measured 285/35 up front and 325/30 in the rear. The brakes are vented steel discs with six-piston calipers up front and a single-piston set at the rear. The steering features electronic power assistance and has M-specific gear ratios for a sportier feel.
The X5 M and X6 M go on sale early next year, as 2015 models, pricing starts at $99,650 for the X5 M, and $103,050 the X6 M. Both figures include a $950 destination charge.
