General Motors announced yesterday plans for a next generation of gas-electric hybrid vehicles that the automaker thinks will sell in big numbers around the globe.

Set to debut in 2010, the Generals next hybrid system will be an upgrade to the current hybrid powertrain, which is available in only three GM models in the United States. The company's new hybrids will deliver three times more power using lithium-ion batteries instead of the current nickel-metal hydride batteries. In addition to delivering a more powerful boost during acceleration, the new hybrid systems also will increase fuel economy and provide brief electric-only power.

Japan-based Hitachi Limited will get the first supply contract for the lithium-ion batteries. Wagoner said he thinks GM can sell well over 100,000 vehicles a year once the new system is rolled out. GM thinks it can win hybrid buyers with a system capable of driving all sorts of vehicles, from four-cylinder coupes to European diesels, a significantly different approach than Toyota, the hybrid market leader that has a mass-selling hit in its iconic Prius sedan.
