I just saw the fuel economy ratings listed on fueleconomy.gov for the 2014 DI 6.2 4x4 at 14 city and 20 highway. I believe that the combined was 17 but don't quote me on that one.

I'm impressed! Too bad you can't get the 6.2 in a low/mid level trim and that it wants 92 octane and won't take e85.

I hope that I'm not repeating something that was already posted here.

I just bought a 2014 CC short bed with 5.3L. this past weekend I went to buffalo and back and average 21.5 mpg on 87 octane. I was impressed with that! Truck has lots of power, more than my 5.3L Avalanche

I was waiting on the 6.2 as we'll but glad I went with the Ltz 5.3 it has enough get up and go. And I drive 70 miles a day. I have been running the 5.3 on corn and it is running great.
