  • Introduction

    When BMW introduced the 745i, Alpina decided to stop modifying the E23 7-series. Alpina did offer a turbocharger upgrade package allowing higher levels of boost.

    However in the UK where the 745i wasn’t available, there was a market for a more powerful 7-series car than the 735i. Therefore Alpina´s U.K authorized dealer Sytner offered the 735i B10. Even though the 735i B10 was built in Great Britain it was a real Alpina with a handbuilt 261 bhp, 3,5 litre, 6 cylinder engine which was delivered from Alpina to Sytner. Both manual and automatic gearboxes were offered.

    The rest of the car was also pure Alpina including special gas-filled Bilstein shock absorbers and progressive rate springs, 16in Alpina alloys, Alpina front and rear spoilers and all of the other smaller bits and pieces which distinguish Alpina´s cars.

    The B10 3.5 accelerated from 0-100 km/h in around 7 seconds and had a top speed of nearly 235 km/h. That is superior to the 745i. The 735i B10 is a very rare car, only 22 were built.

    The wagon cars on the pictures is a special prototype made by “Garage du Bac – Paris”, a special french Alpina importer, but they did not receive the authorization to continue this idea. The wagon has been used as delivery and support car for F2 and stock races in France. It is 50 kg heavier than a ordinary saloon and has a 245 bhp B9 engine. The top speed is 235 km/h.
