M550d is currently available only in left-hand drive
A diesel BMW ‘M5’ will not be offered to British buyers until the next-generation 5-series is launched in about three years’ time.
BMW sources have revealed to Autocar that while the 376bhp, 546lb ft 3.0-litre tri-turbo diesel engine is now offered in the M550d in left-hand drive markets, it can only be mated to all-wheel drive running gear. The current 5-series platform cannot be engineered with all-wheel drive in right-hand-drive form.
However, the next-generation 5-series will be offered in right-hand drive with four-wheel drive, raising the likelihood of the first diesel car to wear the iconic M badge.
