Whether chosen as a coupe, convertible, or four-door Gran Coupe, the 2015 BMW 6-Series offers dynamic driving and massive style.
The BMW 6-Series is larger, more luxurious, and more high-tech than ever, and it’s available in more body types than ever before, too. Coupe, convertible, and four-door Gran Coupe takes on the 6-Series toolkit are all available. On top of that, the M6 range takes all of the best of the 6-Series and turns up the performance.
Styling is one thing the 6-Series range shares across its range, with evocative, finely rendered lines defining the front end, and, in coupe and Gran Coupe forms, the arching rooflines you expect of a sporty luxury car. A taut, sculpted hood, stylized, muscular flanks, and neatly tucked rear end are also common to the range, further telegraphing the 6-Series’ performance potential. The M6 adds a heightened level of urgency to the design, flaring and flaunting its behemoth power.
From the 640i’s 315-horsepower, 3.0-liter turbocharged in-line six-cylinder to the 650i’s 400-horsepower 4.4-liter twin-turbo V-8 to the 560-horsepower M6, the 6-Series range packs speed and performance that scales with the owner’s desires. Of course, curb weights ranging from 4,200 pounds for the coupe to 4,500 pounds for the Gran Coupe damp that aggression slightly, but with BMW’s eight-speed automatic transmission sending power to the rear wheels (or optionally all four with xDrive all-wheel-drive), acceleration is brisk and positive.
The M6 in particular shines in performance terms, acceleration to 60 mph in as little as 4.1 seconds depending on the body style and transmission chosen. A seven-speed dual clutch or six-speed manual with rev-matching are available on the M6. M-specific stability, traction, and dynamics controls further enhance the accessibility of the M6 range’s performance, adjusting steering, powertrain, suspension, and more on the fly. The M6 still has to fight with its size and weight, leaving the brakes perhaps a bit over-taxed on track, but in the real world, it’s a competent and enthralling drive.
The Gran Coupe model offers four doors in a sedan-coupe form factor, with what BMW calls 4+1 seating. Rear-seat access is easier than with the true 6-Series coupe, and the rear seat is a touch roomier, too. Driving dynamics of the two-door are largely preserved, but if you’re after a high-performance four-door for people-moving, the 5-Series or even larger 7-Series may be better options.
Priced at a premium point, the 2015 BMW 6-Series offers interior design and materials to match, with fine leathers, available metal and wood trims, and a wide range of customization available through the BMW Individual program. Standard features include a 10.2-inch wide-screen display hosting BMW’s iDrive infotainment system, and new for the 2015 model year, Dynamic Digital Instrument Cluster display. Navigation includes a standard iDrive touchpad controller for 2015 as well, and 650i and 650i xDrive models now offer a standard M Sport exhaust system.
Other updates for 2015 include a new Launch Control feature for the Sport automatic transmission, a new Harman Kardon sound system upgrade, and a price reduction for the Night Vision package from $2,600 to $2,300.
