Energy council rates “greenest” and “meanest” vehicles for 2007

Washington, D.C. – The American Council for an Energy-Efficient Economy (ACEEE) has named its “greenest” and “meanest” vehicles for 2007. The ACEEE analyzes vehicles based on a “Green Score” measurement that incorporates unhealthy tailpipe emissions, fuel consumption, and emissions of gases that contribute to global warming. This year, no domestic nameplates made the “greenest” list, but only four were listed as “meanest”.

The “greenest” car is the Honda Civic GX, which is powered by natural gas (not sold in Canada); the rest of the top twelve, in order, are the Toyota Prius, Honda Civic Hybrid, Nissan Altima Hybrid, Toyota Yaris, Toyota Corolla, Toyota Camry Hybrid, Honda Fit, Kia Rio, Hyundai Accent, Hyundai Elantra and Honda Civic.

The “meanest”, in order, are the Volkswagen Touareg diesel, Mercedes-Benz GL320 CDI, Lamborghini Murcielago, Jeep Grand Cherokee diesel, Bentley Arnage RL, Mercedes-Benz R320 CDI, Mercedes-Benz ML320 CDI, Maybach 57S/62S, Bentley Azure, Ford F-250 5.4-litre, Dodge Ram 2500 Mega Cab 5.7-litre, and Lincoln Navigator.

“Given the arrival this year of ultra-low-sulphur diesel fuel, having five diesels show up on the Meanest Vehicles list is a letdown,” says Therese Langer, Transportation Program Director of ACEEE. “Fortunately, these same manufacturers have already announced plans to bring much cleaner diesels to the United States in 2008, using an entirely different emissions control strategy.” The ACEEE notes that while diesels are more efficient than gasoline-powered vehicles with similar performance, they produce higher levels of nitrogen oxides and particulate matter, and consequently require more sophisticated emissions control.
