Ahead of next month's Detroit Auto Show, BMW today unveiled a raft of improvements made to their 6-Series coupe, four-door Gran Coupe and convertible as the range enters the middle of its life cycle.

Tweaks to the car are largely related to styling and equipment. In a press release, BMW said that the refreshed 6ers now sport an "adeptly modified design that exudes powerful sports performance and, at the same time, emphasizes the exclusive elegance of these luxury cars," and we couldn't agree more.

The 6-Series Gran Coupe continues to be a strong seller in the range, with nearly one in two buyers opting for the four-door model.

In particular, every 6-Series model has "flared wheel arches and horizontal lines across the rear emphasize the cars' wide track and resultant surefooted handling." Wider is better, as we all know.

Improvements over the 2014 model include standard Adaptive Full-LED headlights, new 20-inch multi-spoke wheels, available Ivory White/Black and Cognac/Black leather accents, the option of Fineline Brown wood trim, the new optional Black Accent Package with piano black interior trim, newly styled exterior mirrors, and a revised front fascia.

Power, of course, comes from either a 3.0-liter turbocharged inline six producing 315 horsepower for the 640i or a 4.4-liter V8 with 445 horsepower. Going all the way up to the 4.4-liter turbocharged V8 engine in the M6 — available on all three models — gets you a dynamic 560 horsepower.

An all-new 6-Series is coming in the next few years, and one that BMW has promised will be more of a Porsche fighter than ever before. In the meantime, this revised 6er should keep the faithful more than happy. Expect to see more when it makes its Detroit debut next month.
