The breadth of today's 6-Series lineup draws competitors from all over the premium map.
Gran Coupes are spiritual kin with cars like the Audi A7, which gets a powerful RS 7 edition for the 2014 model year.
We'd even draw comparisons with the two-door Maserati GranTurismo, since its rear seats are more usable than most grand-touring coupes, even though it has two fewer doors.
The 6-Series Coupe and Convertible have the Jaguar XK clearly in their sights: the XK weighs less and comes across as more elegant, with fewer advanced technologies in its playbook.
The Mercedes-Benz SL Class is quite close in size, space, and purpose to the 6-Series models, even though it's significantly more expensive than the BMW, at least in some configurations.
While the new Mercedes cars—particularly the new SL, and the high-performance SL63 AMG that competes with the M6—offer more visual flair and drama, the BMW models feel as inspiring, capable, and well-equipped.
Those in search of more of a driver's car—without giving up too many of the creature comforts—should consider the Porsche 911.
However you will end up sacrificing some comfort—as well as some of the 6-Series' advanced tech options.
