Audi has released one last pair of teaser images with the upcoming e-tron quattro concept, set to be revealed during the 2015 IAA.

These two new photos shared by AutoBild show us the front end of the machine featuring the Audi logo and a massive chrome grille with e-tron lettering. The image of the back reveals a set of LED taillights and impressively big wheels.

The study is based on the second-gen MLB platform and will have a drag coefficient of only 0.25. Positioned between the Q5 and the Q7 in size, the car will benefit from the matrix laser OLED headlight technology.

The concept will eventually lead to the Q6 production model that will see the light of day in 2018. The road-going vehicle is expected to have an all-electric powerplant with range of more than 500 km (310 miles).
