BMW will unveil a high performance version of its X5 sports activity vehicle at the International Automobile Show, Detroit, in January. The new car will be powered by a 347bhp 4.6-litre engine, with 354lb-ft of torque, accelerating from 0-62mph in 6.5 seconds and on to a maximum of 149mph.

The car is not expected to go on sale in the UK until 2002, and will cost more than the current £44,000 4.4-litre car. Also at Detroit will be the M3 Convertible, and revised M Coupe and M Roadster models with improved engines. Meanwhile, a new 525i Sport is now on sale in the UK, featuring M5 styling and equipment, priced at £29,480.
