I wanted to provide an overview of the MPG I experienced on a road trip I completed in my 2015i Yukon Denali XL. I do not concern myself with MPG nor consider it a decision factor in my purchasing decisions. I have owned several 6.2L V8s in different vehicle platforms but was pretty impressed after checking the DIC a couple times during the journey because I was pushing it hard.

Four occupants, luggage for 4, a large cooler, and two full sets of golf clubs...the truck was loaded front to back. I ticked off ~3500 miles round trip. Mostly interstate, but while gone for three weeks at the destination it was mixed mostly city.

Average MPH: 76 (led foot and cruise was set well over 80MPH majority of the time).
Average MPG: 19.1

Pretty impressive from a V8, 4x4, body on frame SUV. From a comparison standpoint my 2015D Yukon Denali with the 6SPD did the same trip about a year ago and only did 17 MPG.

Long live the V8!

I'm retired so aren't in any hurry
usually go around 70 lower numbers were city driving
Happy with the numbers about 2 MPG better than my 2007 5.3 Envoy Denali
Not bad considering your driving a small house but I love it!!!

Do all 2015 Yukon Denali's have Active Fuel Management system? If so, can the system be turned off/on? If so, how do you do this?
