Alpina, the well know German tuner announced that it is celebrating its 50th anniversary and in order to celebrate this event it will create 50 saloons or estates and 50 similar coupes. The special models will be based on the B5 Bi-Turbo and the B6 Bi-Turbo, and each vehicle will include hand-crafted Edition 50 body as well as trim features and a revised V8 engine.

According to Alpina, the 4.4-liter V8 engine will deliver 600 hp (441 kW) and 800 Nm (590 lb-ft) of torque, making the B5 Bi-Turbo and B6 Bi-Turbo their most powerful models ever developed.

The company says that the heavily-revised engine found on both models received two Alpina-developed water-cooled intercoolers close coupled to the turbochargers, a large-capacity oil radiator and suplimentary coolant radiator, a large-volume air-cooled intercooler located behind the bespoke front spoiler, new light-weight pistons, a high-capacity fuel system and other unique upgrades.

As a result, the engine received an additional 70 Nm (52 lb-ft) and 44 kW (60 hp), offering same high levels of durability. Both models will be able to accelerate from 0 to 100 km/h (62 mph) in 4.2 seconds and a top speed of 204 mph or 328 km/h. Despite these performances, combined fuel economy is 29.7 mpg, while CO2 emissions are 221 g/km.

When it comes to design, the cars feature the first major restyle of the Alpina Classic wheel for more than a decade, with side cuts in each spoke and a reduced weight of each wheel by 15.6 kg compared with the previous 20-inch design. Moreover, the width has been increased to 9” at the front and 10” at the rear, while each wheel features the Edition 50 logo on the rim and shows a clear view of the Alpina Blue brake calipers.

In addition, there is a titanium exhaust system developed by Akrapovic, which saves a further 17 kg compared with a stainless steel system. As standard, Alpina offers a limited slip differential as well as subtle aerodynamic enhancements. Inside, the Edition 50 models feature hand-crafted sports seats in black leather with luxurious Forest Green quilting on the squab and backrest centre sections, yellow and black stitching.

Trim panels are finished in Alpina piano black with Edition 50 and the signature of company founder Burkard Bovensiepen located in front of the passenger. There is also a special ‘1965 – 2015’ logo on metal emblems on the seat backs, carpets and key ring.

Each vehicle will carry a limited edition number displayed on a production plaque located on the centre console as well as on the reverse of the keyring.

Other highlights include ceramic finish controls, a full leather instrument panel and two additional levels of optional interior leatherwork. If you want to buy such a vehicle, you’d better know that Alpina will offer each car in Alpina Green or Alpina Blue or in a bespoke ition 50 Sepia created by BMW Individual. Pricing starts at £86,850 in the UK. [source: Alpina]
