They don't give the specs for the 2010. Just the 2009 which haven't changed since the model was introduced.
I think it's smoke and mirrors like the Chevy Cobalt.
I hope I'm wrong, but I want SPECS. for the 2010.

You might be right! I'm almost tempted to say there is a conspiracy because while under the "new EPA MPG numbers" these cars get slightly better mileage than their non fuel economy counterparts but if you look at the OLD EPA numbers and their CAFE numbers, both the Cobalt XFE and the Accent Blue get the same mileage, to the hundredth of a percent! Now before you get too excited, there is something I should tell you..
Under the OLD EPA MPG ratings and CAFE ratings, all they do is city and highway driving with something like 20 stops along the way, they
do not use the AC and they accelerate gently, no faster than 3.3 mph/sec for city driving and 3.2mph/sec for highway driving. Under the NEW epa MPG guidelines, they not only do the first two tests the exact same way as for the CAFE and OLD EPA MPG ratings, but they add a few more tests, specifically they add a "High Speed Test" which is just highway test but driving 80mph AND accelerating at a rate of 8.46mph/sec, they add Cold Weather startup which is exactly the same city test as before but driving during 20F temperatures, and finally they add the real kicker, the A/C test which is basically the city test except they have the A/C on AND they accelerate at a rate of 5.1mph/sec.
So to conclude, I think how they're able to get that "XFE" moniker and the Accent "Blue" is not from changing the transmission at all! But instead reprogram the ECU into NOT doing certain things like charging the alternator or runs the A/C less aggressively or something, maybe it detects driving on the EPA cycle which REALLY wouldn't surprise me as Toyota was accused of pulling the same ****. Though if that was true, then it'd get better mileage on the CAFE cycle as well, so to look at it positively, I think they reprogrammed the ECU so that less fuel is injected for harsh acceleration but to look at it negatively, maybe they played around with the A/C or used an underdrive on the A/C pulley so that it doesn't operate as strongly.
Either way, this is good news for hypermilers as this means that the "blue" and the "XFE" variants are nothing special and you're perfectly fine with the car you have assuming you have the same car but without the "blue" or "XFE" designations..
