Another thing I've found is that they more closely matched the EPA figures after engine break in. The Matrix got bad mileage when it was new (23 or 24, which for that car is bad) and it greatly increased once the engine had a few thousand miles on it, and I'm now routinely getting 31 or 32 during normal useage, and up to 36 on long trips.
I wonder how old the engines in the cars tested were.
Considering that this comes from the leftists at Consumer Reports, I would expect them to say that the cars don't meet Bush's EPA mileage figures. No such problem existed under the previous administration, of course. (/sarcasm)
