Unadjusted numbers are exactly what the dyno spits out after the car is done. The EPA adjusts the numbers to make them 'more accurate' for how cars are driven today. I believe the unadjusted numbers are what CAFE uses and what are being used in the bill that was just passed the other day requiring the 35 mpg fleet average by 2020. Sadly, this is nowhere near 35 mpg EPA rating.

HA!! I'm getting better than even the dyno combined FE. That's pretty hilarious to me.
