Official: 204 MPH Alpina B5 & B6 Bi-Turbo Edition 50

To celebrate the 50th anniversary of Alpina, the automaker has just revealed the Alpina B5 and B6 Bi-Turbo Edition 50 models. Just 50 units of each car will be created and they incorporate a number of changes over ‘run-of-the-mill Alpina B5 and Alpina B6 models.

For starters, both the Alpina B5 Edition 50 and Alpina B6 Bi-Turbo Edition 50 utilise BMW’s 4.4-litre twin-turbocharged V8 engine. However, power has been increased to 600 hp with torque also rising to 590 lb-ft. The additional power has been achieved through the fitment of new Alpina turbochargers located between the cylinder banks and delivering up to 1.2 bar of boost pressure.

Additionally, shorter air intakes are featured in the engines which also aid in improving throttle response markedly. Elsewhere, an improved intercooler finds its way into the engine bay of both Edition 50 models alongside a larger radiator. Lightweight pistons finish up the modifications to the 4.4-litre twin-turbo V8 engines.

A titanium exhaust system from Akrapovic is also featured with it weighing 17 kg less than an equivalent stainless steel system. An improved limited-slip differential also comes standard on both Edition 50 models.

Elsewhere, Alpina’s Edition 50 models roll on a new set of Classic wheels. The new wheels feature side cuts in each spoke with each set of four wheels weighing 15.6 kg less than previously. Alongside the weight reduction, the wheels are actually slightly wider and measure 20×9 at the front and 20×10 at the rear. An Edition 50 logo adorns each set of wheels with the brake calipers also being painted in blue.

In the cabin, the car’s feature black leather across the seats which is hand stitched alongside Forest Green quilting. A special ‘1965-2015’ is then found on special metal emblems on the rear seats, carpets and the key ring.

Discussing the marque’s 50th anniversary, Alpina chief executive Andreas Bovensiepen said “Alpina is a company that creates subtly stylish, very high performance cars that can be tailored to each customer’s personal requirements, yet offer the long-term comfort and durability required for daily use. We have a unique philosophy and a commitment to engineering excellence that we intend to maintain and build on across the next 50 years.”
