Ok then, let's redo these numbers :

Quote:
Our stop-and-go driving gave us 32.3 MPG,
our suburban driving with a mix of streets ended up at 39.8 MPG.
Extremely careful cruising on the interstate at exactly 55 MPH resulted in a stunning 57.9 MPG.
If you take advantage of the slipstream of a semi-truck (which we, of course, do not recommend), you can easily approach 65 MPG.
Code:
0%      5% less  10% less
32.30    30.69    29.07
39.80    37.81    35.82
57.90    55.01    52.11
65.00    61.75    58.50

Imagine what an aeromod would do for it. It has a rather high stock Cd of close to .30, so cleaning up the aerodynamics to drop the Cd on the 0.1's should allow you to get 60's to 70's mpg on the highway if their drafting mpg figures were representative.

My wifes '05 Malibu dash display is generly 10% over optimistic but my '08 Cobalt XFE is only about 2% over optimistic.

I could deal with the Cruze being 2% optimistic, hopefully it wouldn't be any less accurate then that.

A couple % off isn't a big deal. My built in mpg meter is pretty useless though. It reads low some tanks, high on others, so I pretty much ignore it, other than the instant function when on the highway.

If they did, all Cruzes would be the Eco model ...
It's a lot simpler to NOT built the fuel-guzzler version, and built just the Eco version by default.

My brothers day old Ford Fiesta SFE got 54MPG with the cruise set @ 55mph resetting the factory "MPG avg" once we were at speed and drive 10 miles. No drafting, on extra air in the tire. Then at 70mph it got 44MPG with the same test. My Metro doest better in the city but the Fiesta is the hyw king. He claims to ave 45MPG combine with light hypermiling

So I believe 58mpg @ 55mph with a Cruize ECO because it EPA's 2 mpg better hyw than the Fiesta.
