I took a trip to the Black Hills of South Dakota last weekend. Going down a lot of hills alot of braking I got up to I think 42 EV miles. It was crazy. If I would have had flat terrain after that it would have been great but i used it up driving around all day. With 4 people in the car, going 75 on interstate against a 20-30 mph wind gusts we averaged just over 38 mph.
