The rear-wheel-drive model is likely to sprint from 0-60mph in less than five seconds, and go on to an unrestricted top speed in excess of 200mph. That kind of pace would be enough to tempt buyers away from Mercedes' E55 AMG estate and Audi's forthcoming S6 Avant. Despite the advanced state of its development programme, BMW claims that if the M5 Touring is given the green light for the UK, it won't appear in right-hand-drive form before 2007. Prices would be a little higher than for the saloon, at around £65,000.
