Editor’s note: If you’re looking for information on a newer BMW 6 Series Gran Coupe, we’ve published an updated review: 2019 BMW 6 Series Review.
The 2014 BMW 6 Series Gran Coupe is a 4-door version of the 6 Series coupe, and it’s a pretty special car. That starts with what’s under the hood — if there are two better all-around engines that are offered in the same luxury car, we’ve yet to find them. The 640i Gran Coupe’s smooth turbocharged inline 6-cylinder pairs formidable thrust with excellent fuel economy. The 650i Gran Coupe’s twin-turbocharged V8 is insanely powerful, yet so refined that it’s almost silent in normal operation. The 8-speed automatic transmission ties the whole package together, serving up buttery upshifts or racy rev-matched downshifts when required.
Additional Gran Coupe strengths include a lovely cabin and a bullet-train feel at speeds that just about every high-buck BMW boasts these days. If it weren’t for the styling, which we felt was less daring and cohesive than that of the Mercedes-Benz CLS or Audi A7, we’d have virtually nothing to criticize. The Gran Coupe’s handling does, however, fall a bit short of the "ultimate driving machine" standard set by previous BMWs, which we’ll discuss below. For folks who simply want a 4-door coupe with power and luxury to spare, the 2014 BMW 6 Series Gran Coupe might be just what they need. See the 2014 BMW 6 Series models for sale near you
What’s New for 2014?
The 2014 BMW 6 Series Gran Coupe has an updated iDrive system, and the 640i can now be outfitted with all-wheel drive.
What We Like
Wonderful engines; superb high-speed composure; top-quality interior; plenty of technology; available all-wheel drive
What We Don’t
Somewhat uninspiring to drive for a BMW; small trunk
Every BMW 6 Series Gran Coupe comes with an 8-speed automatic transmission. Rear-wheel drive is standard, and xDrive all-wheel drive is optional.
The 640i boasts a turbocharged inline 6-cylinder engine rated at 315 horsepower and 330 lb-ft of torque. Fuel economy with rear-wheel drive is 20 miles per gallon in the city and 30 mpg on the highway. Adding all-wheel drive (640i xDrive) yields 20 mpg city/29 mpg hwy.
The 650i upgrades to a twin-turbocharged V8 with 445 hp and 480 lb-ft of torque. Environmental Protection Agency ratings with rear-wheel drive are 17 mpg city/25 mpg hwy for both body styles, and adding all-wheel drive yields 16 mpg city/24 mpg hwy.
Standard Features & Options
The 2014 BMW 6 Series Gran Coupe is offered in two trim levels: 6-cylinder 640i and 8-cylinder 650i. All-wheel drive (xDrive) is a $3,000 option on either trim.
The 640i Gran Coupe ($78,550) comes standard with a turbocharged inline 6-cylinder engine, 18-inch alloy wheels, adaptive xenon headlamps, fog lights, a sport-tuned suspension with adaptive dampers, front and rear parking sensors, a sunroof, keyless entry with push-button ignition, leather upholstery, 10-way power front seats with lumbar support and memory settings, a power tilt-telescopic steering wheel, auto-dimming mirrors, dual-zone automatic climate control, iPod/USB and Bluetooth connectivity, a 9-speaker audio system, and the hard-drive-based iDrive infotainment system with a 10.2-in widescreen display, digital music storage, a navigation system and a rearview camera.
The 650i Gran Coupe ($89,850) adds a twin-turbocharged V8 engine and a few extra perks, such as 19-in alloy wheels and 20-way multi-contour power front seats.
Some of the 650i’s extra features are available on the 640i as options. Other options include adaptive cruise control and a 16-speaker Bang & Olufsen audio system. There are several options packages, most notably the M Sport package, which adds aerodynamic tweaks, a higher top speed (155 mph), unique M-design 19- or 20-in wheels, LED headlights, a high-gloss shadowline trim, dark chrome exhaust tips, a sport steering wheel and extensive M interior modifications (including extended Alcantara and leather trim).
Although the 6 Series Gran Coupe is based on the 7 Series platform, its cabin is unique. That starts with the low-slung front seats, which give the Gran Coupe an unmistakably sporty vibe. The 650i’s standard multi-contour front seats are sublime in every way, and interior materials are absolutely top-notch. The sleek dashboard swoops dramatically toward the driver, accentuating the coupe experience.
Predictably, backseat space isn’t close to that of the 7 Series. Even the 5 Series (another spawn of the 7 Series platform) has more room for adults, thanks to its less rakish roofline. Still, full-size humans can fit in the Gran Coupe’s rear quarters, which is a lot more than we can say for the 2-door 6 Series. Trunk space is unchanged from the 2-door model at 13 cu ft.
The 2014 BMW 6 Series Gran Coupe comes with stability control, 4-wheel anti-lock disc brakes, active front head restraints and eight airbags (front, front-knee, front-side and full-length side-curtain). Numerous high-tech safety features are available, including a blind spot monitoring system, lane departure warning and a forward-collision mitigation system with automatic braking.
Neither the government nor the independent Insurance Institute for Highway Safety has crash-tested the 6 Series Gran Coupe.
Behind the Wheel
The 6 Series Gran Coupe is somewhere between the 7 Series and the 2-door 6 Series in terms of athleticism. It’s a highly capable handler; no doubt about it. However, the Gran Coupe is 4 inches longer than the already sizable 2-door 6 Series, so it’s not a car that feels nimble in tight corners. True to its name, the Gran Coupe is really more of a 4-door grand touring car, a phenomenal high-speed cruiser that’s also at home on winding roads as long as the curves aren’t too sharp. We’d give the award for the ultimate driving machine to the Porsche Panamera or Audi A7/S7 in this class, but the Gran Coupe is an immensely satisfying drive in its own way.
Other Cars to Consider
Audi A7 / S7 — The A7’s supercharged V6 has enough urge for most tastes, but the S7 has a delicious twin-turbocharged V8 that might be worth the stretch. Both the A7 and S7 have a nimbler feel than the BMW in spirited driving.
Mercedes-Benz CLS-Class — The CLS comes with a choice of two wonderful twin-turbocharged V8s that bookend the Gran Coupe’s V8. We love the sheet metal’s boldness, too.
Porsche Panamera — The Panamera isn’t a beauty in the eyes of most beholders, but it’s absolutely brilliant to drive.
Used Aston Martin Rapide — If you want to turn heads all over town, there’s the V12-powered Rapide, and then there’s everything else. Let depreciation be your friend. You can find a nice used Rapide if you look hard enough.
The phenomenally fast, yet impeccably refined 650i Gran Coupe is our pick of this litter. It’s a fantastic all-around luxury ride. Find a BMW 6 Series for sale
