Alpina B5 Biturbo Touring

It’s a fairly small, specialised market that Alpina is playing to; last year it sold just over 1100 cars globally, down slightly on its best year of 2007 when 1500 cars were bought. And it’s a market that’s changing rapidly in the UK in particular, as the price of petrol continues to dent the appeal of big, powerful petrol-engined cars like the B5. Hence the reason Alpina’s engineers are working hard to produce a smaller, diesel-engined machine to replace its most popular ever model (in the UK at least), which was the excellent D3.

Yet for a specific type of customer, there is little else to touch a B5 Touring. We drove this car from Alpina’s factory in the middle of Bavaria back to the UK, which was the perfect environment in which to sample its mile eating capabilities. It’s hard to think of many other cars that would have felt so comfortable over the same journey, or as quick, and which could have swallowed so much kit while returning just over 25mpg.

Back in the UK, on our more congested, less well surfaced, rather more fiercely speed restricted roads, the B5 Touring still makes an awful lot of sense. It’s a soothing, relaxing car to drive that just so happens to go like stink if and when you use the loud pedal. And its eight-speed semi-automatic gearbox works a treat in all of its various dynamic modes; as does the similarly sophisticated electronic suspension, which has been tuned by Alpina to provide a broader repertoire of abilities than a factory BMW.

Having said that, the B5 Touring is not a car you’re going to enjoy as much as an M5 on a tight country road. It may mask the effects of its weight extremely well most of the time, but the bottom line is that it still weighs 1990kg; you’re always going to be fighting an uphill battle when trying to control that much weight. Best to head for the A-roads and switch on Classic FM.

Should I buy one?

If you have a lot of money, a couple of other sportscars to dart around in when the desire arises, plus the need for a machine that can dispatch hundreds of miles in very short order without even breaking into a sweat, then yes – because there’s nothing quite like a B5 Touring when it comes to trans-continental mile-munching.

If not, you could argue than the £76k, 500bhp B5 Touring is a day late and a dollar short when it comes to the current era of motoring. In which case, wait for what Alpina comes up with next; it could be a much more relevant kind of car.
