Power for the X6 M comes from a twin-turbocharged 4.4-liter V8 engine that is also found under the hood of the M5, the more practical X5 M and the aforementioned M6. For use in the X6 the eight-cylinder has been tuned to generate 567 horsepower between 6,000 and 6,500 rpm and 553 lb-ft. of torque from 2,200 to 5,000 rpm. An eight-speed M Steptronic transmission works with a M-specific version of BMW’s xDrive all-wheel drive system to send the V8’s power to all four wheels. The transmission can be left in “drive” or it can be controlled via shift paddles mounted behind the steering wheel.
The X6 M’s suspension has been stiffened and lowered by 0.3 inches but comfort isn’t an issue thanks to BMW’s Dynamic Damper Control technology. The system offers three driver-selectable modes called Comfort, Sport and Sport +, respectively. There are similar settings for the X6’s steering system, ensuring that it is just as at home on the road as it is on the track.
Visually, it’s nearly impossible to confuse the X6 M with a standard X6 on which it is based. The range-topping model stands out thanks to a revised front end with more air inlets, side gills with M badges, M-designed door mirrors, an exhaust system with four tail pipes, a rear spoiler and functional air diffuser. Overall, the add-ons help make the X6 more aerodynamic and create noticeably more down force.
Buyers looking to further stand out can order the X6 M in one of two M-specific paint colors called Long Beach Blue Metallic and Donington Grey Metallic.
Model-specific alloy wheels shod in Michelin Pilot Super Sport tires cover six-piston calipers up front and single-piston calipers out back.
