2018 X6 M

The X6 M sits at the top of BMW's Sports Activity Vehicle (SAV) hierarchy. It blurs the line between SUV and high-performance luxury car thanks to a powerful M6-derived V8 engine, a coupe-like roofline and a generous amount of cargo space.

Under the Hood

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.

Although it tips the scale at over 5,100 pounds, the X6 M can reach 60 mph from a stop in four seconds flat and go on to an electronically-limited top speed of 155 mph. Fuel economy checks in at 14 mpg in the city and 19 mpg on the highway thanks in part to a standard start/stop system.

Born and raised on Germany's Nürburgring track, the X6 M is equipped with an engine lubrication system that can operate normally at up to 1.2g of lateral acceleration. The all-wheel drive system was also bred for performance and it is capable of sending 100 percent of the engine's power to either the front or the rear wheels depending on traction and road conditions.

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.

Looking the Part

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 downforce.

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.

Life Aboard

The track-focused treatment continues inside with a M-specific instrument cluster, sport seats for the front passengers and a meaty M-designed three-spoke sport steering wheel.

The driver-oriented dashboard features a color display for the latest generation of BMW's ConnectedDrive infotainment system. ConnectedDrive enables the passengers to get directions with real-time traffic information, surf the internet on the go, change the climate control settings or pick a different radio station by either using the touch screen, the iDrive knob mounted next to the gear selector or the car's voice control system. Alternatively, passengers can manually input an address by using a touchpad-like surface integrated into the top of the iDrive controller.

Although its shape and its engine might suggest otherwise, the X6 remains a utility vehicle at heart. As such, it offers 26.6 cubic feet of trunk space with five occupants on board and 59.7 cubic feet with the rear seats folded flat.

Standard and Optional Features

The X6 M comes generously equipped with auto-leveling Xenon Adaptive Headlights, programmable daytime running lights, LED fog lights, power-folding and heated door mirrors, rain-sensing wipers, a space-saver spare tire, 18-way power-adjustable front seats with a three-stage heating function, a leather-upholstered dashboard, a cargo cover, Merino leather upholstery, a two-way power glass moonroof, a keyless ignition, parking sensors on both ends, a power tailgate, an auto-dimming rear-view mirror, Bluetooth connectivity, navigation, a universal garage door opener and a rear-view camera.

The list of standalone options includes a rear-seat entertainment system, a 16-speaker Bang & Olufsen sound system, night vision with pedestrian detection, a park assist function that can automatically park the X6 and enhanced enhanced USB and Bluetooth plus smartphone integration.

Occupant Safety

The X6 M comes standard with front, side and head airbags as well as BMW's Active Roll Stabilization system and a Dynamic Stability Control system that can be fully turned off when it's not needed such as when driving on a track.

Key Competitors

The BMW X6 M's only direct competitor is the Mercedes-AMG GLE63 S Coupe. Buyers not set on the four-door coupe look can also look at the Land Rover Range Rover Sport SVR and the Porsche Cayenne.
