Done on a Dyno, but with road loads provided by the manufacturer. So if done on a Dyno, which many are, you can "game" the system. Hello.......Hyundai? Anyone home?

Some do. On the highway at 70 (ish or so) our Cruze won't come close to the EPA sticker. But our Audi Q5 easily met or surpassed at the same speeds.

My experience as well. For most GM cars 70 and up costs you 2 to 4 mpg off the EPA rating.

I don't know that I've ever owned a car, foreign or domestic, that consistently beat whatever the sticker MPG figure was.
This is just an example of CR trying to make itself more important than it actually is. Supposedly unbiased but singling out a single manufacturer?  |
EPA uses the road for some but dyno for others. But not sure what determines which one is used.
Also CR is that way. Trying to be more relevant than they probably should be.
