The folks at Alpina bridge the gap between a full factory outfit and traditional tuners. It currently only builds around 1,700 cars a year, but you’re not going to find any massive rear wings or garish paint from the company. Instead, the business has been perfecting how to make BMWs better for the last 50 years and has decided to celebrate with its most powerful road model yet.
For the Edition 50 models, Alpina is crafting 50 sedans or wagons and 50 coupes for European buyers based around its B5 Bi-Turbo and the B6 Bi-Turbo, respectively. The real birthday present is the upgraded, twin-turbocharged 4.4-liter V8 under the hood. It makes 591 horsepower and 590 pound-feet of torque, a bump of 59 hp and 52 lb-ft from the regular versions. The extra grunt comes thanks to additions like an optimized intake, water-cooled intercoolers near the turbos, lightweight pistons and a titanium exhaust. Alpina claims that these celebratory vehicles can get to 62 miles per hour in 4.2 seconds and a top speed of 204 miles per hour.
Beyond just the major improvement in power, these special vehicles wear Alpina’s more aggressive, though still understated body kit. They also ride on an updated version of the company’s famous wheels that feature added side cuts on the multiple spokes to reduce weight.
These exclusive cars are only available in Alpina’s own shades of green and blue, plus a special color called Edition 50 Sepia from BMW Individual. There are also special logos on the seatbacks and center console to further promote the models’ limited nature. Celebrating the brand’s birthday in one of these high-speed vehicles retails for 86,850 pounds ($130,000) for buyers in the UK.
