Transgressions

I think it's probably a pretty safe bet that most car manufacturers have transgressed in their time. Some have gotten away with it, and others are yet to be caught at it.
As to the question in the op, the bigger transgression, lying about emissions or lying about fuel economy. The lie is the transgression, so it's pretty much the same thing, at least as I see it.
