HERE COME THE PLUG-IN DIESELS!

Although it's unclear whether some of the hottest green cars being showcased in Geneva will make it to the U.S. (or will go into production at all), what we see in the next generation of hybrid and electric vehicles is pretty exciting. Volvo debuted its three-in-one Volvo V60 Plug-In Hybrid concept car - the first plug-in diesel - at the Geneva Auto Show. Drivers will have three options with the push of a button: pure, power and hybrid. Pure starts all-electric for 30 miles then goes to diesel. Power will go from zero-to-62 in 6.9 seconds with the combined 285 horsepower produced from the diesel and electric motors. And the hybrid mode will take you about 745 miles on one tank of fuel. The vehicle is expected to start selling in Europe next year but it's unclear whether it will make it to U.S. shores and, if it does, whether the diesel engine will remain.

Land Rover also showed a diesel hybrid, the Range e, expected to get over 40 MPG but there was no word on production plans. Another concept is the Nissan Esflow, a sexy-looking electric sports car with a 142-mile range. The Toyota Yaris hybrid unveiled in Geneva is expected to go on sale in Europe next year and we hope to hear about plans to bring it to the U.S. very soon. One car that does have plans to come to the U.S. in late 2011 is the Audi Q5 hybrid, which will get combined MPG numbers in the 36 MPG range. Ailis Aaron Wolf Hybrid Owners of America
