The second-generation X6 M Sports Activity Coupé (SAC) made its debut in 2015, combining the characteristic features of the BMW X family — robustness, agility and everyday usability — with the high performance that defines an M vehicle. The M TwinPower Turbo V8 for the X6 M is the most powerful engine ever developed by BMW for an all-wheel-drive vehicle, a 4.4-litre V8 producing 567 hp and peak torque of 553 lb-ft. The crossover accelerates to 100 km/h in 4.2 seconds through the standard eight-speed M Steptronic transmission with Drivelogic. Exterior design modifications that separates the X6 M from the milder X6 includes large air intakes at the front end, side gills with a model badge and air breathers, signature M exterior mirrors in twin-stalk style, a typically M four-tailpipe exhaust system and a rear spoiler. M-specific, forged 21-inch M light-alloy wheels are also standard.
