Half a century ago, Alpina was founded in the German city of Kaufbeuren. Originally a producer of typewriters, the company transitioned into the infinitely more interesting business of making fast BMWs, tweaking carburetors and cylinder heads instead of stringing ink ribbons. In the years that followed, Alpina would produce more than a few successful race cars, eventually moving on to concentrate primarily on street cars in the late ’80s.
To help celebrate its long history of hotrod Bimmers, Alpina has introduced the B6 Bi-Turbo Edition 50. Based on the BMW 6 Series coupe and convertible, Alpina laid its hands on just about every aspect of the stock car, with upgrades applied to the exterior styling, interior equipment, and of course, all those mechanical bits under the skin.
Only 50 examples will be built. As a showcase of Alpina’s tuning prowess, the B6 Edition 50 is sure to provide more than a few incentives for those looking for a Bavarian rocket ship that still comes with an original factory warranty.

Alpina has a rich, 50-year history with BMW. The pair have built some of the most impressive luxury and performance vehicles ever to roll off a German assembly line. Unlike aftermarket tuners that begin work with a finished production car, Alpina works directly with BMW inside its factories to build specialty vehicles for the most picky of customers. The pair’s latest products are diesel-powered 4 Series coupe and convertible. Starting with the bones of the 4 Series, Alpina juices up the 3.0-liter, bi-turbo, inline six-cylinder to make an impressive 350 horsepower and 516 pound-feet of torque. Sadly, the oil-burner is not available in U.S.-spec 4 Series BMWs. Those across the pond will enjoy the benefits of diesel, getting more than 44 mpg on the highway. The added grunt to this twin-turbo beast means sub five-second zero to 60 mph times.
Alpina didn’t just make the D4 Biturbo faster. Added to the running gear are auxiliary springs with thicker anti-roll bars and adjusted camber and toe-in settings for the Alpina-specific wheels and Michelin Super Sport summer tires. The car already makes use of electronically controlled dampers that give the driver adjustability in the suspension. BMW’s limited-slip differential helps put power to the ground.

Grand Tourers have a long tradition at ALPINA. It began with the legendary BMW ALPINA 3,0 CSL lightweight Coupé in the early 1970s, a car that caused a great furore, both as a race car and as a street car. It was with this car that ALPINA won the European Touring Car Championship in 1973 and 1977. Since it débuted in 1978, friends of BMW 6 Series Coupés have awarded the 300 bhp BMW ALPINA B7 Turbo Coupé with 330 bhp / 512 Nm in the S-Version) cult status, making it a desired collector’s car. The elegant BMW 8 Series was the basis for the BMW ALPINA B12 5,7 Coupé, identifiable at a glance thanks to its carbon-fibre bonnet with NACA ducts.
