I've been playing with my driving style on my relatively short commute (10 miles) that is mostly highway driving to see what i can find out. If i drive without any climate control and as gently as possible, i can get around 210 Wh/mi. Driving more "normal" (not avoiding accelerating for merging and passing) i will get around 220 Wh/mi. If i run climate control while driving normal, it's more like 250-260+ Wh/mi.
Longer drives definitely improve this as well, i've had a few longer distances drives average 190-200 Wh/mi. All with aeros.
