A report from Autocar claims that the Audi Q6 e-tron family will have a coupe-style version called Audi Q6 Sportback e-tron. These models will have smaller dimensions compared to the Audi e-tron and Audi e-tron Sportback, respectively. While the Q6 Sportback version is yet to appear in spy pictures, it would have a softer roof that drops steeply into the raked D-pillars. It would sit lower and will achieve a better drag coefficient value (possibly 0.25 Cd or lower). The better aerodynamics may allow a range longer by 5-8 miles (WLTP).

The coupe-style roofline of the Sportback version would reduce headroom and cargo volume up to 5 percent. In the e-tron’s case, the SUV version offers 39.8 inches of headroom in the front and 38.6 inches of headroom in the rear. The same dimensions of the Sportback version are 38.1 inches and 37.9 inches, respectively. Similarly, while the SUV offers a luggage capacity of 28.5 cubic feet (second-row seats up)/57.0 cubic feet (second-row seats down), the Sportback version offers a luggage space of 27.2 cubic feet (second-row seats up)/54.5 cubic feet (second-row seats down).
