I drove a little over 34 miles on all electric yesterday. I ran it until there was 0 miles of range left on electric and it went about another mile then switched to gas. I was very pleased. I had it on cruise for about half those electric miles where the speed limit was 50-55. The road was rolling with a couple good sized hill climbs. I was very easy on the throttle and never punched it. It's impressive how smooth the transition the gas is. I really like checking the Eco-Score on the app. I actually find it pretty useful to see how my driving affects the way the car behaves. I'm probably in the minority, but I enjoy a slow, easy going car ride more than a sporty, white knuckle ride. My wife is the race car driver out of the pair of us.
