The BMW M5 Touring is a special machine in today’s automotive landscape, as station wagons are becoming increasingly rare. But what makes it even more remarkable is its rumored powertrain, which could make it a force to be reckoned with in the supercar world.

New spy photos have emerged showing the M5 Touring in action at the Nurburgring. At first glance, it may resemble our previous sighting from July, but upon closer inspection, it appears to be closer to production. The taillights and the quad exhaust outlets, which are distinctive features of the M5, have been updated. The new exhaust pipes seem slightly larger, and based on the car’s performance through the corners, it’s clear that they are being put to the test.
