Most people are familiar with BMW's M Series performance cars, but fewer know there's a level above that. As an example, check out the BMW Alpina B6 Gran Coupe.
Like other Gran Coupe models, the Alpina B6 is a sedan with a low, coupelike roofline. The Alpina version features unique wheels, paint and trim, plus an upgraded engine (600 horsepower and 590 pound-feet of torque) with corresponding improvements to the transmission and suspension. But the Alpina B6 Gran Coupe's strongest selling point is exclusivity: Outside of a BMW dealership, you're unlikely to see another one out in the wild.
Current BMW Alpina B6 Gran Coupe
The Alpina B6 Gran Coupe is sold in a single, very well-equipped trim level. Along with Alpina-exclusive colors and trim, the Alpina B6 borrows heavily from the 6 Series options list, with 16-way adjustable seats, a 16-speaker premium stereo and four-zone automatic climate control. There are options to get even more, including upgraded seating and trim, active safety and driver aids, and an even higher-end Bang & Olufsen stereo.
All BMW Alpina B6 Gran Coupes are powered by a 4.4-liter twin-turbo V8 tuned for 600 hp and 590 lb-ft of torque, 40 hp and 90 lb-ft more than the version of the engine used in the M6 Gran Coupe. An automatic transmission and all-wheel drive are standard. Edmunds clocked the B6 Alpina to 60 mph in a lightning-quick 3.6 seconds. The standard-fit adaptive suspension delivers a brilliant blend of handling agility and ride comfort.
The cabin, with its 16-way power-adjustable front seats, is supremely comfortable; the interior trim is top-notch and can be made even better with upgraded leather and wood trim options. But the Gran Coupe's sleek roofline limits backseat headroom, and taller adults will have to be careful not to hit their heads on the door frame when getting in (not that there will be much room for it once they get inside). Trunk space is also limited, and the liftover is high. If you need something more practical, the Alpina B7 sedan is a better choice.
Used BMW Alpina B6 Gran Coupe Models
The first-generation BMW Alpina B6 Gran Coupe made its debut in 2015, supplementing the Alpina B7 sedan. For 2016, BMW upgraded the B6's engine to produce 600 hp and 590 lb-ft of torque (up 60 hp and 50 lb-ft from the 2015 model). Since then, BMW has added a few extra features, but otherwise there have been no major changes.
