If you want to drive the most environmentally friendly or "greenest" vehicle, you need to think small or think hybrid. According to the American Council for an Energy-Efficient Economy (ACEEE), one third of the top 12 vehicles that rank as the greenest of 2008 feature hybrid powertrains. These vehicles combine an internal-combustion engine with an electric motor for improved fuel economy and reduced emissions.
A nonprofit organization, the ACEEE is dedicated to advancing energy efficiency as a means of protecting the environment and strengthening the economy. Each year the ACEEE publishes the Green Book, listing the Green Scores and environmental information about vehicles available in the new model year, as well as a list of the 12 "greenest" vehicles available that year.
"Hybrids stand out, even after being taken down a notch by the new fuel economy calculations," said ACEEE vehicle analyst Shruti Vaidyanathan. "And sales rose by a whopping 40 percent last year. This interest in hybrid vehicles should shine the spotlight on other green vehicle technologies that can significantly improve fuel efficiency."

Honda Civic GX. Scoring 57 points for 2008, the Civic GX operates on compressed natural gas (CNG). While it may not go as far on each gallon of fuel as some other entries, its combination of high efficiency and near-zero emissions makes it the highest-ranking vehicle for the environment. Note that the Civic GX is for sale to retail customers only in California and New York.
Message Board: Are domestic vehicles being fairly judged by the ACEEE?Another European model added to the list for 2008 is the
MINI Cooper /
MINI Clubman. The fun-to-drive
MINI lands in the eighth position with a Green Score of 44. And unlike last year when there were no domestic cars on the list,
Ford has the sole domestic offering to make the cut. The
Ford Focus takes the ninth position with its 2.0-liter PZEV 4-cylinder engine.
The second, third and sixth eco-friendliest vehicles in the U.S. are all hybrids — the
Toyota Prius,
Honda Civic Hybrid and
Nissan Altima Hybrid, respectively. The only other hybrid to make it into the ACEEE's top 12 happens to be the largest car on the list — the
Camry Hybrid. Coming in tenth, this midsize hybrid earns a Green Score of 44, matching the MINI Cooper, Ford Focus, Honda Civic and
Honda Fit.
