Another world premiere at the 2015 Geneva Motor Show is the all-new ALPINA B5 Edition 50.

With four exclusive special models, ALPINA celebrates its 50th birthday this year. The Edition 50 for BMW ALPINA B5 Biturbo and BMW ALPINA B6 Biturbo is limited to 100 pieces worldwide.

ALPINA also treats its customers with a rich performance increase, because the 4.4-liter V8 biturbo delivers now no less than 600 hp, making those the most powerful official vehicles in the company’s history. The maximum torque is also raised from 730 to 800 Newton meters.

All four variants of the ALPINA Edition 50 – B5 and B6 sedan, Touring, Coupe and Convertible – run from 0 to 100 km/h in 4.2 seconds. The top speed, depending on the model, is limited to 323-330 km / h.

Besides the performance improvement, the Edition 50 has its weight-optimized with forged wheels which are 15.6 kg lighter than the standard 20-inch wheels. An optional high-performance brakes with four-piston fixed calipers and Brembo 395 mm diameter brake discs at the front ensures high-performance braking.

At the rear, wider tires also are used in order to ensure, together with the mechanical differential lock, an increased degree of locking for added traction. Damper and control systems have been specially adapted to the lighter wheels and the increased engine performance.

A lightweight exhaust system from Akrapovic titanium saves another 17 kilograms and promises, with their active damper control, an unforgettable sound experience. Carbon panels on four tailpipes and exclusive in ALPINA blue or green frozen colors complete the exterior.

A special highlight for ALPINA lovers is the optional heritage interior with black and green seats, and backrest center panels with diamond quilting in yellow and black – a truly unique design that is available exclusively for the Edition 50.

All 100 copies of the BMW Alpina Edition have special interior trim: wood piano lacquer decorated with a “Edition 50″ lettering and an autograph from Herr Bovensiepen. All ALPINA emblems in the interior are made of silver and bear the year ‘1965 – 2015′.
