My 2012 seems to have narrow parameters. During this summer (I bought used about a month ago) I average 4.4-4.5 when I drive it like any other car (highway speeds, AC, mix of D and Eco). I average 4.7-4.8 when I drive at lower speeds, no AC, all Eco, moderate acceleration, etc. Whether I drive it like a reckless teen or a little old lady, I cannot seem to maintain an average outside the 4.4-4.8 range, and normally it is 4.6-4.7. We will see what winter brings, but since it lives in a garage I'm a bit hopeful.
