Official images have emerged of the revised BMW M5. They were leaked onto BMW's website after the M5's configurator was updated ahead of schedule.

The current M5 has been on sale since 2011, and so it's perhaps unsurprising that the facelift has altered very little. As the first spy shots suggested, the M5's grille has been tweaked to incorporate larger vertical slats, as on the M6, and the headlights are also slightly different.

Inside, the M5 receives the steering wheel from the M6, with narrower spokes and a smaller centre than previously. The iDrive controller is now touch sensitive, but the interior ostensibly remains identical.

While the standard 4.4-litre, twin-turbocharged V8 will be carried over unchanged, BMW is expected to offer a Competition Package on the revised M5. This will increase power from 552bhp to 567bhp and also add new wheels, a revised M Dynamic mode and firmer suspension. This appears to be a direct riposte from BMW to the threat posed by the uprated Jaguar XFR-S and Mercedes-Benz E63 AMG S.

The 2014 model-year M5 will be available later this year. No pricing has yet been announced, but expect a slight rise over the £73,350 of the current model.
