Background
Back in the 1990s, a diesel car was hardly the most thrilling of prospects - and definitely not the choice for anybody seeking sporty performance from their car. While they may have been fine for more undemanding drivers seeking frugality and longevity, the overall sense was that diesels were noisy, slow, dirty and lacking the finesse of a petrol-burning motor.
In 1996 though, the German car firms and close collaborators BMW and Alpina decided to try and change that - by creating ‘the ultimate diesel sports engine’. Alpina is much more than ‘just’ an aftermarket car tuner. Its associations with BMW began in the 1960s, but by the 1980s, the relationship between the two had become so tight that Alpina became officially recognised as an automobile manufacturer in its own right, albeit using BMW vehicles as the starting point. Typically the Alpina process involves tuning an engine, then delivering it to a BMW factory for fitment, after which the nearly finished car returns to Alpina to be further upgraded, with an emphasis on interior luxury and high levels of equipment. When complete, the finished machine boasts Alpina rather than BMW badging - just to make sure that anybody seeing it knows it’s something just a bit out of the ordinary.
Anyway, back to the 1990s, and the project to inject a little more dash into diesels. BMW offered Alpina a choice of two engines; its existing 3-litre six-cylinder unit (as found in the 530d) or new 3.9-litre V8. Alpina plumped for the well-proven straight-six. The engine was comprehensively reworked, with its stand-out modification being two turbochargers, boosting power from 184bhp to 238bhp and offering a whopping 369lb ft of torque.
The car into which it was installed debuted at the 1999 Geneva motor show as the Alpina D10 BiTurbo. It was based on the E39 530d - albeit with Alpina’s trademark interior and exterior touches - and produced in small numbers between 2000 and 2003. With a 0-60mph time of just under seven seconds and a top speed of 158mph, it certainly proved that diesel-engined cars didn’t have to be boring.
