Interesting. Doesn't state their driving habits, but for my 22 platinum hybrid I'm averaging between 20 and 21 on my commutes while cruising at 70mph. I've gotten 23mpg on longer road trips cruising at 70. City driving I would average about 16 though. So far I'm at 22k miles.
I'm in the bay area California so pretty hilly too. That does mean I coast quite a bit going down hill and regain some mpg that I lose accelerating up hill though I guess.
Like most mpg tests, the drivers right foot is where the biggest variables are.
They’ve already come out saying it’s for performance over efficiency gains, and the fuel economy ceiling was definitely bumped higher (however impractical it may be to achieve) so I can’t see it really causing waves of controversy.
the F-150 PowerBoosts on Fuelly seem to be getting 19ish mpg, which is certainly better but eh, the gas 2.7L F-150 is only a smidge behind which disappoints me.
