My e-tron's usually in All Road mode with the A/C on. Last Tuesday, I did a 30-mile trip, mostly highway and some city streets. I put it in Efficiency mode, A/C on Eco, fan on low. Mostly kept it at 60 mph on the highway (the limit). So many slowpokes! I did go up to 70 mph a couple times to pass some super slow drivers. Didn't want to hold up traffic. The way back was in a total downpour – wipers going nuts, lights and hazards, A/C normal, fan on medium. I was blown away that I got 3.2 miles per kWh overall! My gas cars never got their advertised MPG, no matter how I drove. So so happy with my e-tron!
