An interesting post on GreenCarReports suggests that 9 car models already meet the 2025 EPA standards. Frustratingly, however, the nine cars are not listed. The original report does have another graph with a little more insight (page 434).
Two of the nine cars are the Toyota Prius and the Ford Fusion hybrid, not surprisingly. But the other cars remain mysterious.
The graphic also shows that the Mitsubishi Mirage is not one of the nine.
