Vehicle Details Interior  Dashboard, center console, gear shifter view photo

The 2018 BMW 6 Series includes an attractive and functional steering wheel with numerous controls and a touch-sensitive iDrive controller that rounds out an already complete cockpit. With premium materials everywhere, exquisite fit and finish, wood or carbon-fiber accents, a high-end audio system and supremely comfortable driver's seat, BMW’s 2018 6 Series leaves a lasting impression. Not surprisingly, rear-seat room is tight in the convertible models, but acceptable on the Gran Coupe. Trunk space is largely unaffected when the convertible's top is folded.

Exterior   photo

The recently redesigned nose on the 2018 BMW 6 Series is subtly effective, with the number of vertical bars in each "kidney" now nine instead of 10. The rear end looks menacing when viewed head-on, which is just as it should be. But whether you choose the Gran Coupe or Convertible, a 6 Series boasts an athletic profile, defined by a long hood and a striking crease that's nearly the length of the body.

Notable Standard Equipment

As one of BMW's higher-end models, the base 6-cylinder 2018 640i Convertible and Gran Coupe come very well-equipped with leather and wood inside, xenon headlights, a navigation system with 10.2-inch display and touch-sensitive iDrive controller, dynamic cruise control and rearview camera. A new 650i adds a V8 engine, along with even softer Nappa leather, 20-way-power front seats, 19-inch wheels and a 12-speaker/500-watt audio system. BMW 6 Series xDrive models offer all-wheel drive, and all BMWs offer four years or 50,000 miles of scheduled maintenance.

Notable Optional Equipment

While there are stand-alone options like all-wheel drive available for BMW’s 6 Series for 2018, most of the desirable upgrades are divided into packages. An Executive Package adds ventilated front seats, soft-close doors and a futuristic head-up display that projects travel information onto the windshield so you can focus on the road. Definitely get the wonderful Bang & Olufsen sound system, and performance-minded drivers should check out the active steering and Adaptive Drive. The Black Accent package adds high-gloss black trim on the grille and interior trim, black tailpipes, bi-color 20-inch alloy wheels, and black Nappa leather.

Under the Hood

Two engine options tempt prospective BMW 6 Series buyers. The 640i gets a turbocharged 3.0-liter inline-6 that makes a robust 315 horsepower, while the 650i gets a 4.4-liter twin-turbo V8 engine that puts out 445 horsepower. The 640i and 650i use an 8-speed automatic transmission, with either rear- or all-wheel drive (RWD, AWD). To save on its thirst for premium fuel, the 2018 BMW 6 Series uses auto start/stop to cut engine power at idle.

3.0-liter turbocharged inline-6 (640i, 640i xDrive)
315 horsepower @ 5,800-6,000 rpm
330 lb-ft of torque @ 1,400-4,500 rpm
EPA city/highway fuel economy: 19/28 mpg (AWD convertible), 20/29 mpg (RWD Gran Coupe and convertible), 19/28 mpg (AWD Gran Coupe)

4.4-liter twin-turbocharged V8 (650i, 650i xDrive)
445 horsepower @ 5,500-6,000 rpm
480 lb-ft of torque @ 2,000-4,500 rpm
EPA city/highway fuel economy: 17/25 mpg (RWD convertible, Gran Coupe), 16/25 mpg (AWD convertible, Gran Coupe)

Pricing Notes

The Manufacturer’s Suggested Retail Price (MSRP) of the base 2018 BMW 640i Convertible undercuts some of its more lofty competition, but $86,095 -- including the $950 destination charge -- is still serious coin. If you want a V8 engine, you'll be looking at nearly $97,500. The 4-door Gran Coupe drops that price to $80,795 for the V6 and $92,195 for the V8. Want all-wheel drive? Add another $3,000. Options inflate the price quickly, and it's not hard to get to six figures. That said, the 2018 6 Series is competitive against cars like the Mercedes-Benz E-Class coupe, and it seriously undercuts cars like the Porsche Panamera and Maserati GranTurismo. Before buying, be sure to check the Fair Purchase Price to see what others in your area are paying for the BMW 6 Series. Long-term resale value should be about the same as a Mercedes-Benz E-Class Cabriolet, but lower than an Audi S5.
