2012 Alpina B5 Biturbo Sedan

Do you love the notion of the 507-horsepower, twin-tubocharged Alpina B5 Touring, but just can't get behind a high-performance family wagon? Alpina has good news for you. The company has officially pulled back the curtain on the new B5 Sedan, and the vehicle boasts the same wicked driveline as its long-roof twin. That means there's a dizzying 516 pound-feet of torque pouring out of the same forced-induction 4.4-liter V8. A ZF eight-speed automatic transmission takes care of gear-swapping duties while a range of subtle aesthetic tweaks set this bruiser apart from its more mundane counterparts.

There is no mistaking the flashy, 20-inch Alpina wheels, however. According to the company, the combined kit allows the B5 Sedan to clip off a 0-62 dash in just 4.5 seconds. That's plenty quick by our estimation and about on par with the new 2012 BMW M5. Which would you rather have? Hit the jump for the brief press release while you mull it over.

BMW ALPINA B5 BITURBO
Performance, Elegantly Styled

ALPINA automobiles are defined by their finely balanced mix of driving dynamics, comfort and everyday luxury. Add to that exceptional functionality and the result is the BMW ALPINA B5 Bi-Turbo.

In Touring form, the B5 Bi-Turbo smartly combines the exclusive sophistication of the Saloon with pronounced functionality and versatility. Make no mistake, the Touring offers up to 1670 litres of storage space and an ingenious luggage compartment concept, despite its luxury high performance genes.

A finely honed suspension and chassis configuration combined with variable dampers makes for an exemplary ride comfort while simultaneously providing sharp handling and excellent high-speed stability.

The V8 Bi-Turbo accelerates the Saloon from 0-62mph in 4.5s while 730Nm of torque paired with the exceptional 8-speed Sport Automatic Transmission with SWITCH-TRONIC means power is always readily available. Modern, dynamic and well toned in appearance – the B5 Bi-Turbo has all the right visual qualities to make it the perfect companion for business and leisure.
