Good point. They tout that the Q8 e-trons have improved range.
The way I drive my Ioniq 5 reports 180 miles at 80% instead of the 250+ that others get. I get around 2.5-3 miles per kW on average.
So the e-tron likely would be worse, but the furthest commute I have is 80 miles total so not a deal breaker, but a great reason to lease instead of buy.
