I spent my last tank seeing how good I could do by paying much more attention to my speed, and coasting and engaging ev whenever possible. It's tough as I have a commute in a lot of stop and go roads that are 45mph or higher so there's a lot of accelerating I need to do. My end score wasn't too bad though. Trip A:535 mi .... CONS:57.5 MPG .... Avg:28 mph My first three tanks were actually low to mid 40's so that's a significant improvement. I think it added up to about 100 miles more on that tank of gas which is a free couple of gallons of fuel just for paying more attention and driving better. Was hoping for 60 or better, but I'd really have to do some grandma driving and start pi$$ing off the people behind me to do that with my commute.
