To give you an idea of the cars involved the top group included a BMW M5 (V8), the mid group had an M3 (V6) and the bottom group had a Neon SRT-4. The worst observed mileage they recorded out of all the cars (7 or 8 total) was from the 2.4 liter turbo Neon.

Turbo cars do well in the EPA's test cycle because it doesn't require using the turbo much. When driven hard they don't do as well.
