The second generation Q7 will exhibit some serious weight loss, about 880 lbs., a byproduct of new lightweight aluminum construction. The supercharged 3.0L V6 would be the obvious choice for the base engine in the new Q7, with diesel and plug-in hybrid setups both strong possibilities.
This second generation Audi SUV will share its new platform with the Porsche Cayenne and the Volkswagen Touareg, both of which also benefit from a large weight loss thanks to the new aluminum structure.
The Q7 mule you see in the photos is merely a test vehicle for Audi’s internal re-workings done on the newest generation SUV, but the organs of the car undergoing tests suggest that the skin of the new Q7 will be revealed soon. The Audi has always been bulkier than its Cayenne and Touareg counterparts, so expect the size and general shape of the vehicle to stay the same.
