When it comes down to it, there will likely be one primary reason to pick the BMW M6 Gran Coupe over its platform-sharing sibling, the BMW M5 sedan: style. Both will serve up a twin-turbo 4.4-liter V-8 engine good for 560 horsepower and 500 pound-feet of torque, and both will seat four adults comfortably, but the M6 Gran Coupe keeps more of an eye on style than its brother.
BMW knows the best way to pitch the M6 Gran Coupe is to get as many potential buyers as possible enamored with the car’s lines. Though BMW released a two-minute video at the car’s revealing, it’s since followed up with a pair of videos giving more exposure to the M6 Gran Coupe’s interior and exterior styling.
Inside, the car closely resembles the M6 Coupe, which has a more upscale feeling than the M5 sedan. Like the M6 Coupe, you get an impression of personal luxury that’s absent from the M5, which seems more directed at hauling driver and passengers from point A to point B as quickly as possible, in better-than-average comfort.
The cockpit doesn't break any new styling ground, nor does it take the car in a different direction than the M6 Coupe, but it doesn’t lose anything in the translation, either. If you really wanted an M6 Coupe, but need four doors, this is the car to shop.
The same can be said about the M6 Gran Coupe’s exterior styling, too. Most will prefer its plunging roofline over the more conventional lines of the M5 sedan, but be aware that its good looks will cost you rear-seat head room. Perhaps the best way to present that argument is this: if your passengers require easier rear-seat entry, the M5 is the car you want.
Though pricing hasn’t yet been announced, we expect the M6 Gran Coupe to be priced a few thousand higher than the $108,295 BMW M6. That’s quite a stretch from the $92,095 BMW M5 sedan, so perhaps price will play as big a factor as style in the purchase decision.
