My 99 Cobra had a 4.6L V8 w/ 320+ HP. The best MPG I got was around 26MPG. Daily driving it was 21-22MPG.
Yup, those numbers look almost identical to mine. Which they should. My '01 is basically identical to the upgraded '99.
It will be interesting to see the 2015 Mustang. Rumors are independent suspension and a diet. It's also being sold in Europe for the first time. Along with the 2.5L Turbo, 300HP power plant. I think Ford's smart enough that this won't be a 'ricer' and will continue it's pony roots.
Yeah, it should be really interesting to see. I realize I am among the minority in this opinion, but I was really disappointed by the '05-'14 Mustang designs. The one good thing that came from it is that Coyote 5.0. Hopefully it'll go into a car equally as forward thinking and advanced in 2015.
