Alpina has finally graced the world with a handful of images and all of the gritty details about the all-new 2011 B5 Bi-Turbo after its debut at the Goodwood Festival of Speed. The company has managed to bless the BMW 5 Series with a mythic 507 horsepower and 516 lb-ft of torque. How, you ask? The B5 makes use of the same twin-turbo, all aluminum V8 found in the car’s big brother, the B7. That means that there’s a full 4.4-liters of displacement sucking down 1 bar of pressure for the two turbos under the hood. Sounds like a party.

The eight-pot is bolted to an eight-speed automatic transmission that Alpina co-developed with the gear-swapping gurus at ZF. If the mood strikes you, the driver can click through the gears via buttons mounted on the back side of the steering wheel, though given the massive amount of work Alpina put into the transmission, odds are you’re better off letting the car do the work for you.

There’s also a completely reworked suspension on board that includes slightly shorter springs and unique control arms that help eek a little more camber out of the front wheels. Combined with the electronically adjustable suspension, the company claims to provide an altogether sharper driving experience. Speaking of wheels, Alpina has equipped the B5 Bi-Turbo with a set of the company’s epic 20-inch rollers.
