BMW makes a number of subtle updates to its M6 high-performance two-door coupe and convertible for 2010, including a more streamlined, sportier exterior shape, larger headlights, revised bumpers, and updated exhaust pipes. BMW also stretches the M6's wheelbase for 2010, resulting in a roomier cabin. However, the M6 retains its compact, high-revving, naturally aspirated V10 powerplant, which displaces 5.0 liters. The V10 produces 500 hp and 383 lb-ft of torque, and drives the M6 from 0 to 60 in 4.5 seconds and to a top speed of 155 mph. The engine links to a seven-speed Sequential Manual Gearbox (SMG) with drivelogic, which matches shift patterns to each individual driver.

Based on the higher-end 5 Series trims, the 2010 M6 rides on an independent suspension with M calibration, which includes stiffened springs, dampers, and anti-roll bars, and a modified rear axle. An Electronic Damping Control system enables drivers to choose from Comfort, Normal, and Sport modes. Other M-specific features include Dynamic Stability Control with M Dynamic Mode and all-season traction with an M Variable Differential Lock, which monitors inputs from the suspension, powerplant, and road surface, and transmits drive power to individual wheels to ensure optimal traction.

The M6 also comes with speed-sensitive power steering, which links to the M Driving Dynamics Control system, enabling drivers to switch to sport-oriented steering by pushing the M Drive button located on the steering wheel. The M6 cruises on 19-inch light-cast alloy wheels with high-performance tires.

The M6's interior features continue to impress. Merino leather upholstery comes standard, and the M sport heated front seats feature 14-way power-adjustment, adjustable side bolsters, four-way lumbar support, and a three-setting memory system. The multi-function steering wheel comes equipped with paddle shifters for the transmission, while the instrument cluster displays a unique M design. The 13-speaker Logic7 Surround Sound AM/FM audio system includes two subwoofers, HD radio, digital sound processing, and MP3 capabilities.

The M6 comes in coupe and convertible trims for 2010. The coupe features a reinforced carbon-fiber roof, while the convertible comes equipped with a fully lined power soft-top roof with a heated glass rear window. Other exterior features include xenon adaptive headlights, rain-sensing windshield wipers, heated exterior mirrors, and Park Distance Control with front and rear sensors.
