2018 M6 Gran Coupe New Car Test Drive
The BMW 6 Series is a luxury car with an arching roofline that comes as a coupe, convertible, or fastback sedan called the Gran Coupe, which has longer wheelbase for more rear passenger room.
The 6 Series is a cruiser, not a high-performance car (not counting the much more expensive M6 with 560 horsepower). The 6 Series got a minor facelift for 2016, so there are no significant changes for 2017, mostly just new glossy black interior trim, with chrome around the iDrive display.
The standard engine in the cruiser BMW 6 Series is a turbocharged 3.0-liter inline-6 making 315 horsepower and 330 pound-feet of torque, enabling it to accelerate from zero to sixty in a quick 5.3 seconds; that's the BMW 640i. Next engine is a V8 making 445 horsepower and 480 pound-feet of torque, enabling the BMW 650i to accelerate from zero to sixty in 4.3 seconds; that one-second difference is huge in the seat of your pants.
Both engines use an 8-speed automatic transmission. Rear-wheel drive is standard, with all-wheel drive available, which BMW calls xDrive.
The six-cylinder gets 21/30 miles per gallon City/Highway, 24 mpg Combined. The 6 Series hasn't been crash-tested by the government or insurance industry. Being a high-end German car, there's a ton of available safety equipment, including forward collision warnings with automatic emergency braking at city speeds; blind-spot monitors; a surround-view camera system; and lane departure warnings. Night vision cameras with pedestrian detection and active steering assistants are also available.
The 2017 BMW 640i Coupe ($77,600) comes with leather seats, dark wood trim, 18-inch wheels, adaptive LED headlamps, 10-way power adjustable front seats, keyless ignition, WiFi hotspot capability, rearview camera, and iDrive, an infotainment interface with 10.2-inch touchscreen.
The 640i Convertible ($85,100) and longer-wheelbase BMW 640i Gran Coupe ($79,800) are similarly equipped. (Prices are MSRP and do not include destination.)
Options include the M Sport package that adds 19-inch wheels and high performance tires, black brake calipers, LED fog lamps, and Alcantara headliner.
