BMW Alpina D5 Bi-Turbo unveiled image

After releasing the based on the 6-Series Cabrio, BMW tuning specialists at Alpina got their hands on the new 5-Series and decided to upgrade its power and give it a sporty touch, a fact well appreciated by those who think the M5 is a motorway.

Alpina says that its D5 Bi-Turbo is powered by a 3.0 liter twin-turbo straight-six unit, which is delivering a maximum 345 horsepower, but in a world where everyone is “used” to supercars this might not be that impressive.

What really catches our eye is the fuel consumption which is in the 530d territory, with 6.2 liters of fuel burned in an average cycle every 100 kilometers, the same as its diesel brother which offers only 241 horsepower.

The D5 Bi-Turbo’s engine is connected to an eight-speed ZF Switch-Tronic Sport Automatic gearbox revised by Alpina, and the “new 5-Series” can accelerate from 0 to 100 km/h in 5.2 seconds, with a top speed of 270 km/h or 168 mph.

“In 1998 Andreas Bovensiepen, together with Stuck, Menzel and Duez, won the 24h Nürburgring at the wheel of a BMW 320 diesel engined race car – which was certainly unconventional at the time. This success provided the impetus for ALPINA to start the development of a high performance version of the BMW 3 litre inline six cylinder diesel engine utilising two turbochargers. The result was phenomenal: the D10 Bi-Turbo, on basis of the BMW 5 Series, held the record for the fastest production diesel saloon for many years! Especially long distance drivers valued the unique combination of excellent handling, brilliant comfort and long cruising range”, as Alpina says in an official statement.

Being an aftermarket upgrade, Alpina also fitted both versions of the 5-Series with new 20 inch Classic rims, wrapped in Michelin Pilot Super Sport tires.
