My main worry with the Q8 is the efficiency. Considering I'm just under 4m/kwh lifetime efficiency in the Nissan - getting nearer to 2.5 in the Audi is going to be a bit depressing. Plus it'll be the wife mostly driving it - and she's got no idea how to drive an EV efficiently.
That's the main issue with the Q8. How did Audi increase the range over the previous fat etron? Whack in a massive battery but still get max 2.5 miles per Kw. It would have been good to have them work on the efficiency rather then just use up more raw materials in a massively inefficient car.
