Under the Hood
Power for the X5 M comes from a twin-turbocharged 4.4-liter V8 engine that is also found under the hood of the aforementioned M5, the M6 and the X6 M. For use in the X5 M 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 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 5,200 pounds, the X5 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 X5 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 wheel wheels depending on traction and road conditions.
The X5 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 X5'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 X5 M with a standard X5. 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 X5 more aerodynamic and create noticeably more downforce.
Buyers looking to further stand out can order the X5 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.
The track-focused treatment continues inside with a M-specific instrument cluster, sport seats for the front passengers and a M 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 engine might suggest otherwise, the X5 remains a utility vehicle at heart. It offers 35.8 cubic feet of trunk space with five occupants on board and 76.7 cubic feet with the rear seats folded flat.
