Greenest Vehicles of 2006

The American Council for an Energy-Efficient Economy (ACEEE) recently recently released their 2006 Green Book. The Dodge Ram SRT 10--with a 8.3-liter, 500 horsepower, 10-cylinder engine--gets 9 mpg in the city and 12 in the city. Jim Kliesch, the Green Book's author and principal vehicle analyst, said "You can't expect to be environmentally friendly under those circumstances."
