Here are the official photos of the Alpina B5 BiTurbo the folks at Alpina debuted at the 2011 Geneva Motor Show. The B5 BiTurbo treatment has been given to none other than the new BMW 5-Series Touring. The B5 BiTurbo BMW 5-Series will be powered by the same twin-turbo 4.4-liter V8 as the sedan variant, and it will produce some 507-horsepower and 516 lb-ft or torque.
The power from the engine runs straight to the rear wheels via an eight-speed sport automatic transmission coming from ZF. The B5 is capable of sprinting from 0 to 60 mph in under five seconds, and the top-speed sits at 187 mph. Of course, this beauty comes wrapped in all the Alpina trimmings, including an exterior aero kit and the company's signature 20-spoke wheels.
