It may not look much different, but BMW’s new 5-series promises to be even more popular with company car drivers, thanks to some significant engineering enhancements.

On sale from March, the revised range of saloons and Tourings boast engines that are up to 25% more fuel efficient than before, as well as a host of interior detail changes and a mild facelift.

Thanks to the use of a new fuel injection system, nearly every engine in the range returns more miles to the gallon than ever before, with the 525d being 21.5% more efficient, the 530d 13.5% and the 535d 17.5%. There are also significant savings across the petrol line-up, with the 525d being 25.3% more fuel efficient. Prices range from £26,980 to £49,805, with slight increases across the range.

Of less relevance to fleets will be the new M5 Touring, powered by the saloon’s 5.0-litre V10 engine producing 507bhp. It will cost £67,075 when deliveries begin in March.
