Geneva, Switzerland – General Motors has announced that it will introduce a second-generation version of the GM Hybrid System with a new, more powerful lithium-ion battery, as another key element in its overall global strategy to improve fuel economy and reduce CO2 emissions. The announcement was made at the Geneva Motor Show by GM chairman Rick Wagoner.
Hitachi Vehicle Energy Ltd., a subsidiary of the Tokyo-based Hitachi Ltd., will supply an advanced lithium-ion battery that will help make the next-generation hybrid system nearly three times more powerful than the system it replaces. Depending on the engine and vehicle application, an overall fuel economy improvement for cars and trucks using the system is expected to be up to 20 per cent.
The next-generation system will built on the belt-alternator-starter hybrid technology currently available in the Chevrolet Malibu, and Saturn Vue and Aura. It will complement the company’s Two-Mode Hybrid System, which debuted in 2007 on the Chevrolet Tahoe and GMC Yukon.
“In order to have a real impact on reducing oil consumption, oil imports, and CO2 emissions, advanced technologies must be affordable enough to drive high-volume applications,” Wagoner said. “We plan to roll out this next-generation hybrid technology globally, across our brands and regions, starting in 2010 in North America, and we expect that volumes will eventually exceed 100,000 units annually.”
The new technology was showcased at the Geneva Show in the Saab 9-X BioPower Hybrid concept car. The concept is capable of a projected fuel consumption of 4.9 L/100 km when running on gasoline over the combined cycle, with CO2 emissions of 117 g/km.
