Unfortunately, you have to buy the roof rack specifically designed for the e-tron. Even though the roof rack for other Audi models (like the Q5) appears that it will fit, it will not (of course, right????) There are tiny holes that do not line up correctly unless you purchase the e-tron rack. Just a heads-up though.... I purchased the e-tron rack and the rubber stripping that fits inside the rails to decrease wind noise, DOES NOT actually fit. I called Audi and they sent new stripping and it doesn’t fit either. Otherwise, the rack is nice and easy to install. Mine cost a few hundred. Good luck!
