BMW is about to pull the wraps off of its first M5 Touring in 14 years, but leaked images have made their way online before the big reveal. A pair of what appear to be official press images shared by Autospy show the front and rear of the Audi RS6 Avant rival, finished in striking Isle of Man Green metallic paint. It also features an illuminated grille surround, while down back the M5 Touring differs from the regular 5 Series Touring with its more aggressive bumper and prominent diffuser.

The M5 Touring will be officially revealed on August 15 US time as part of Monterey Car Week. The new wagon will likely be powered by the same twin-turbo 4.4-litre plug-in hybrid V8 with a single electric motor found in the M5 sedan.

On its own, that engine produces 430kW of power and 750Nm torque, though the transmission-mounted electric motor brings total system outputs to 535kW and 1000Nm. The PHEV M5 is one of the most powerful BMWs ever produced, but it’s also among the heaviest, tipping the scales at 2435kg in sedan form, with the figure expected to go up even further for the M5 Touring. In the sedan, drive is sent to all four wheels via an eight-speed automatic transmission, with BMW claiming a 0-100km/h time of 3.

5 seconds. Thanks to a 18.6kWh lithium-ion battery pack, electric-only range in the M5 sedan is 69km.

WLTP fuel economy figures range between 1.6L/100km and 10.3L/100km depending on the battery’s charge level.

All Australian-delivered M5 sedans feature the M Driver’s P.
