In brief: The Environmental Protection Agency has released it's Green Vehicle Guide for 2010.
The word

The guide has two sections: SmartWay and Smartway Elite. The list results for either choice will also vary by state, since different states have different EPA requirements.
The results are tabulated using a sliding scale of 1-10 on two criteria. The first scale measures fuel economy (EPA rating of MPG) and the second measures CO2 output. To qualify as a SmartWay, the car must achieve a 6 on both scales and a total score of at least 13. To qualify as a SmartWay Elite, the car must achieve a 9 on each scale.
On our list below are California (the most stringent EPA rules) cars with a SmartWay Elite rating. This produced 12 winners. They are listed by ranking and alphabetically for ties.
The following were rated 9.5 and 10:
- Ford Fusion Hybrid
- Honda Civic Hybrid
- Honda Insight (2 models)
- Mercury Milan Hybrid
- Toyota Prius
The following were rated 9.5 and 9:
- Ford Escape Hybrid
- Lexus HS 250h
- Mazda Tribute Hybrid
- Mercury Mariner Hybrid
- Nissan Altima Hybrid
- Toyota Camry Hybrid
And so ...
Impressive list and a great site to check before going to the dealership to look at new cars.
