Yeah, EPA cycles are like traffic light grand prix these days, then they adjust downwards. Nothing that hugely improves steady state MPG is gonna show up much in them, and aerodynamics barely figure. The worst thing is that they're tending to make it look like that practically every compact to fullsize car gets "somewhere between" 20 and 30mpg, which probably makes the buying public figure they'll get a fullsize because it's "only 2mpg worse than the Aveo"
I remember The RoadWarrior..To understand who he was, you have to go back to another time..the world was powered by the black fuel & the desert sprouted great cities..Gone now, swept away..two mighty warrior tribes went to war & touched off a blaze which engulfed them all. Without fuel, they were nothing..thundering machines sputtered & stopped..Only those mobile enough to scavenge, brutal enough to pillage would survive. The gangs took over the highways, ready to wage war for a tank of juice
My 350z is rated at only 26 mpg highway, and I have always gotten 28mpg @75 mph average. Once in while it goes to 26, sometimes 30- and my scangauge always shows it at 31-33mpg for some reason. Maybe since I use cruise control all the time, but otherwise I'm not sure why my mpg's are better than rated.
