Alpina is celebrating its 50th birthday in the only way it knows how to: turning BMWs into luxurious performance monsters. Alpina will build 100 special cars in celebration of this milestone, with 50 of them being sedans or wagons and the other 50 being coupes. Alpina will base the sedans and wagons on the B5, while the coupes will be based upon the B6.

Both the B5 and B6 Edition 50 models will make use of a 4.4-liter twin-turbo V-8, but with some serious modifications. Alpina enhanced airflow by shortening the air intakes and keep the forced air cool by way of an intercooler. Also added in are lightweight pistons, an optimized intake system, a lightweight Acrapovic exhaust system, and a high-flow fuel system.

All of these modifications inject an extra 60 horsepower and 52 pound-feet of torque, giving the 4.4-liter V-8 a total of 600 horses and 590 pound-feet of twist. This power travels through a revised automatic transmission, to a limited-slip diff out back. This setup allows the Edition 50 models to hit 60 mph in just 4.2 seconds and top out at 204 mph.

At the corners are 20-inch wheels that are not only wider than the standard Alpina wheels – 9 inches wide on the front and 10 inches wide on the rear – but they are also lighter by a total of 15.6 kg (34.4 pounds). Hiding behind these Edition 50-badged rims are blue brake calipers.

In the cabin, the Edition 50 models come with handcrafted sports seats in black with Forest Green quilted inserts. The Piano Black trim piece on the passenger side features an “Edition 50” badge and the signature of the company’s founder, Burkard Bovensiepen. Additionally, metal emblems on the seatback display the years of the company, “1965 – 2015,” and the production number of each car is on a plaque on the center console.

Buyers can have Alpina paint their car in one of three colors: Alpina Green, Alpina Blue, or Edition 50 Sephia. Prices for the Edition 50 models will start from £86,850 ($129,093) in the UK., and there is no mention of U.S. availability.
