“The BMW 640i Xdrive is the gentleman's sports car. It offers power and reliability while giving the appearance of an elegant high end import vehicle. The iDrive system is intuitive and syncs with my Apple smartphone to allow CarPlay, which was a huge deciding factor. I hope to keep this car a long time as they do not make this model anymore. Could be a collector one day.”
2018 BMW 6 Series: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2018 BMW 6 Series is the arrival of the all-new 640i xDrive Gran Turismo, a roomier hatchback-style model with standard all-wheel drive. The Convertible and Gran Coupe receive only light appearance updates, and the two-door Coupe leaves the U.S. lineup.
About the 2018 BMW 6 Series
Mixed year: the Convertible and Gran Coupe are late in the third-generation 6 Series family (F12/F06, facelifted earlier in the cycle), while the Gran Turismo (G32) is first year in the U.S. lineup.
BMW positions the 6 Series as a stylish grand tourer: a car family built more for fast, comfortable long-distance travel than for stripped-down sportiness. Across its body styles, the core promise is strong turbo power, a rich cabin, and distinctive design that feels more special than a typical luxury sedan. Buyers choose it for elegance and presence first, with the Gran Coupe adding rear doors, the Convertible adding open-air touring, and the Gran Turismo adding space and everyday usefulness.
The 2018 lineup covers three distinct roles: an open-top Convertible, a low and sleek four-door Gran Coupe, and the more practical Gran Turismo. The Gran Turismo has a higher seating position, generous rear space, a power liftgate, and a 10.25-inch touchscreen, while 650i versions of the Convertible and Gran Coupe add a twin-turbo V8 and Harman Kardon audio. The low-volume ALPINA B6 Gran Coupe stands out with a 600-hp V8, all-wheel drive, and its own suspension tuning and design details.

Frequently asked questions
What is the biggest change to the 2018 BMW 6 Series?

Is the entire 2018 BMW 6 Series redesigned?

What is the difference between the 2018 6 Series Gran Turismo and Gran Coupe?
The Gran Turismo is the more practical model, with a hatchback, higher seating position, generous rear space, and standard all-wheel drive. The Gran Coupe is a lower, sleeker four-door focused more on style and traditional grand-touring comfort.

Is a 2018 BMW 6 Series meaningfully different from a 2017 model?
It is meaningfully different if you are considering the Gran Turismo, which is new for 2018 and offers much more cargo flexibility. The 2018 Convertible and Gran Coupe are much closer to their 2017 counterparts, with no major redesign.
