The dealer told me that the trans shifted harder in sport mode,but the book says nothing about that. Was hoping someone knew. I guess I'll have to do some research on my own. Thanks anyways...
But if you do buy one, drive in ECO mode for a couple hundred miles, then use Sport Mode to run it up thru the gears frequently to get a nice break in.
On the same road, at the same speed, I get the same instantaneous mileage in ECO and Sport. However, over pretty much any reasonable drive, ECO mode is always worth a couple mpg long run. Sport is a lot of fun for canyon carving.
The recent flash seems to have made ECO mode more responsive on on steep uphill passing--no longer seem to need to pre-select Sport mode when getting ready for the only passing zone in 10 miles behind a "flatlander"
I agree... my butt will tell me what is the best ride and gas mileage for me.... I just bought this 2012 Overland and have been using auto , "butt" I'll try the sport mode...
