How Green is Your Machine?

Are you thinking about buying a new car? Check out the rankings of the greenest and meanest cars on MSNBC.com. The American Council for an Energy-Efficient Economy ranked the "greenest" and "meanest" 2007 cars based on fuel economy and emissions -- as well as the estimated impact of those emissions on health and global warming. Surprisingly, the Toyota Prius did not come in first. The Honda Civic GX came in first and the Volkswagon Touareg came in last as the meanest car on the road, even meaner than a Lamborghini Murcielago, a Maybach, and a Bentley (according to this study.)

The Civic GX NGV: looks like a Civic, drives like a Civic, and runs on clean, domestic natural gas.
