Alpina B5 Bi-Turbo and B6 Bi-Turbo Edition 50 introduced image

Alpina has introduced two special edition models of the B5 Bi-Turbo and B6 Bi-Turbo.

The Edition 50 special versions have been based on the B5 Bi-Turbo and the B6 Bi-Turbo and they have been created by tuning company Alpina to celebrate its 50th anniversary. The two models will get piano black trim panels with the Edition 50 and the company’s founder, Burkard Bovensiepen, signature, the “1965 – 2015” logo on the carpets, on the seat backs and on the key ring, along with several other tweaks which will help them stand out even more compared to the regular versions.

The Alpina B5 Bi-Turbo and B6 Bi-Turbo Edition 50 will also get the full leather instrument panel, Lavalina leather hand-stitched for the steering wheel, a production plaque on the center console and so on. A limited slip differential is also offered in standard and each car will be available in Alpina Blue or Alpina Green finishes, or in the bespoke Edition 50 Sepia signed by BMW Individual.

The 4.4 liter V8 engine has been heavily revised too and attention has been paid to air flow optimization, charge density and thermal stability. The total output produced by the unit now stands at 600 HP (441 kW) and 800 Nm (590 lb-ft) of torque, meaning that the two vehicles are the most powerful road cars ever developed by the tuner. An extra 60 HP (44 kW) and 70 Nm (52 lb-ft) of torque have been added to the engines in the B5 Bi-Turbo and B6 Bi-Turbo, compared to the standard models. Prices will start from 86,850 GBP in the UK and a very limited number of units will be introduced.
