I mean yeah how i drive is the biggest effective contributor to mpg. but even to use the fuely website as a reference would leave you with the fact that it gives the 2006 cobalt a higher mpg than the 2013 focus. I mean realistically i think its in the gearing at this point. cobalt does 5th at 40 mph, while the focus can go into fifth much earlier. The gearing allows it to run at 2.5k rpm at 65, while in the focus the rpms are well above that(anything above 500 rpm means its using more gas).
