Anyone know why the EPA ratings on the 2011 is 1mpg higher than the 2010s? And if it actually does get better economy?
I have a 2010 QC Sport 4x4 with about 2500 miles on it and so far I am averaging right at 16mpg. I'd do better if I didnt have to sit in line getting on base in the morning. I am happy with that since thats what I got out of my 07 GMC that I traded in and I have a little bit more power than that 5.3.
