Like any other true BMW M car, the M6 Gran Coupe is a vicious performer with performance that easily shoves you into the back of those lovely bucket seats. There's 552 horsepower and 500 lb-ft of torque to exploit, and when equipped with the seven-speed dual-clutch transmission, 60 mph comes up in only 4.1 seconds. The rare six-speed manual is marginally off that pace but still only requires 4.3 seconds to hit 60. These acceleration times make the M6 faster than a Mercedes-AMG CLS 53, but slower than a Mercedes-AMG E63 S. The maximum speed is a limited 155 mph as standard or 190 mph with the limiter removed as part of the M Driver's Package. The M6 is also the only Gran Coupe not to offer all-wheel-drive. While sending power exclusively to the rear wheels will please purists, both the AWD-equipped CLS and E63 S are easier to manage at higher speeds. The same can be said of the current BMW M5.
Using the same engine as the F10-generation M5, the M6 Gran Coupe provides similar performance. The 4.4-liter TwinPower V8 produces 552 hp and 500 lb-ft of torque and is mated to a seven-speed M dual-clutch transmission with drivelogic - this feature makes it possible for the driver to customize transmission shift times. A six-speed manual is a no-cost option but you won't see them around too often. There's also the option to increase performance further with the Competition Pack, which adds another 40 hp to the maximum output while leaving torque unchanged.
The engine is massively effective at hurtling the M6 Gran Coupe down the road at unruly speeds. Although there is some turbo lag lower down in the rev range, once the M6 gets going, it is unrelenting all the way to its red line. While the engine has a welcome V8 growl, it's also a tad artificial and not as characterful as the naturally-aspirated, ballistic V10 used in the E60 M5, one of the few caveats that accompany turbocharging. You will, however, come to appreciate the way in which the M6's huge torque reserves allow for comically easy overtaking, even at higher speeds.
The seven-speed dual-clutch transmission can lurch a bit at lower speeds around town, but when used in anger is a fine partner to the V8, delivering extremely fast shifts and allowing the driver to get in on the action more than in a traditional automatic. The six-speed manual may have something to say about that, however, and this transmission also features rev-matching on downshifts.

There's a price to pay for all of that power and performance. EPA-rated economy numbers for the M6 Gran Coupe DCT are 14/20/16 mpg on the city/highway/combined cycles. A 21.1-gallon fuel tank means that the M6 can achieve a combined cruising range of 337 miles. The manual transmission model has slightly better figures of 15/22/17 mpg. For a better balance of power and economy, the cheaper Mercedes-AMG CLS 53 returns 21/27/23 mpg. Owners should note that the M6 requires premium unleaded gas.
