In a logical extension of its portfolio, BMW has launched the M6 Gran  Coupe. Identified by the automaker as "perhaps the perfect combination"  of the M5 and the M6, it is a stretched M6 that sits on the exact  wheelbase of the M5. Created essentially from the parts bin, the M6 Gran  Coupe's hardware was pre-determined from the start. And that’s a good  thing.

Under the hood of this rear-driver sits the 560-hp, 4.4-liter  turbocharged V-8; BMW's imprecise TwinPower moniker actually refers to a  twin-turbo here. Maximum torque is 500 lb-ft, available at 1500 rpm,  and all 560 horses are served when the tach spins to at 5750 before  arriving at a 7200-rpm redline. BMW claims that the sprint from zero to  60 mph takes a mere 4.1 seconds. That's as quick as the M6 coupe and a  somewhat-inexplicable 0.3 second quicker than BMW says the lighter M5  requires. Top speed is a governed 155 mph, which is reached "in only a  few seconds more," as the press release optimistically states. Top speed  can be raised to 190 mph with the addition of the M Driver’s package.  The engine is mated to a seven-speed dual-clutch automatic. There’s no  word yet on the availability of a six-speed manual for the M6 Gran  Coupe—nor the coupe or convertible, for that matter—which would not only  provide a genuine shifting experience but also shave 33 pounds from the  four-door’s weight, as it does when fitted in the M5.

The M6 Gran Coupe is equipped with an extremely capable chassis, which  includes an electronically controlled limited-slip differential,  electronically controlled shock absorbers, and a rear subframe bolted to  the body. This car still uses hydraulic power steering, electronically  adjustable and rather superior to the electromechanical power steering  found in lesser versions of the 5- and 6-series. Carbon-ceramic brakes  are optional, and they will lower weight by a remarkable 43 pounds. The  20-inch aluminum wheels displayed on this car are specific to the M6  Gran Coupe.

The M6 Gran Coupe is a long sedan from the outside, but from the inside,  the coupe moniker comes alive. The seating position in the front is low  and snug, just like in the standard M6 coupe, and the rear seats do not  offer the room you might expect from a four-door of its size. There  actually is room for five, but the fifth person won't be  happy—regardless of how petit he or she happens to be. BMW is well aware  of the rear-passenger seating arrangement, referring to it as  “four-plus-one.”

But practicality is not what the M6 Gran Coupe is about. Instead, it is  one of the most beautiful four-door sedans on the market, an automotive  dream of luxury, performance, and indulgence. And it’s a good thing this  four-door coupe is directed toward all those desirable characteristics  and not practicality, because when it hits showroom floors in the summer  of 2013, expect to see a sticker price approaching $110,000. At that  price, it will cost nearly $20,000 more than a base M5. But that’ll be  worth it, purely for the sake of owning the prettiest M5 on the planet.
