EPA caught VW cheating - how does the car know it's being tested?
"What I'd like to find out someday is what the actual difference "on
the road" is in drivablity between the cars in "cheat" mode versus
when they run with all the emissions turned on like they are supposed
to. It would be funny if there really wasn't very much difference and
they did this just to get 31.9 mpg instead of 31.2 mpg and 0-60 of
12.0 seconds rather then 12.3. "
Ahh, the "FQ".
