NEW BMW ALPINA XD3 Bi-Turbo

The shape of the Alpina XD3 Biturbo may be familiar, but this BMW X3-based model is the first SUV in Alpina’s history. That in itself is significant enough, but the fact that the XD3 is also the fastest-accelerating diesel-engined SUV you can buy makes it something of a landmark vehicle.

The stats are deeply impressive. In Alpina spec, BMW’s already stonking twin-turbo 3.0-litre diesel gets a 36bhp power boost to 345bhp and an extra 52lb ft of torque at 516lb ft, largely thanks to optimised air intake and exhaust flows. That’s enough to propel the 1910kg XD3 from 0-62mph in an eye-watering 4.9sec – a level of acceleration that you’d need a Porsche Cayenne Turbo to beat.
