K, been messing around with the car the last few days (GTL AWD) and I've been running in different drive modes. (all in auto 2 regen). I have found that my mi/kwh has been considerably higher using sport than in normal or eco mode. Not what I have expected at all. With the temps in the mid 30's all week, it's been a good week to try this out. I'm talking a half mile difference (2.7 to 2.2) eco and normal seem to be about the same but sport mode is just way better. Don't get why, but I'm going to drive in sport for now on.
