Green Cars on Display in Geneva

Green cars were on display at the Geneva Auto Show last week, fueled by rising oil prices and environmental concerns.

Car makers presented an array of cars that run on a variety of sources, from electricity to diesel. The Saab 9-X BioHybrid, for instance, won recognition for Best Concept for its 1.4-liter BioPower turbo engine backed by GM's next generation hybrid system. Daimler showed a Mercedes SUV, the BlueTEC Hybrid. Nissan said it would launch an electric car in the U.S. in 2010, and release it worldwide in 2012.

General Motors confirmed its $4 million investment in Think Global, a Norwegian electric car maker, which debuted its Think Ox at the show, a five-seat car with a range of 125 miles per charge.

Daimler said it has a hydrogen model that can reproduced affordably in large quantities, but the lack of infrastructure presents a barrier. For others, biofuels, such as ethanol, are the name of the game. For instance, Lotus displayed a version of its Exige 270E Tri-fuel that runs on gasoline, ethanol and methanol.

Toyota, maker of the wildly successful Prius, also debuted its iQ model, which it bills as the world's smallest four-seater.
