GM announces next generation hybrid system in Geneva

Rick Wagoner, Chairman, General Motors, announced today at the 78th International Geneva Motor Show, that GM would introduce a second-generation version of the GM Hybrid System with a new and more powerful lithium-ion battery.

This lithium-ion battery will enable the next generation GM Hybrid Systems to be thrice as powerful as the earlier system. Contingent on engine and vehicle application and aided by the new system, the fuel economy for cars and trucks are expected to improve by 20 per cent. The increased power from the lithium-ion battery can also be used in bio fuel engines, global power trains and new high efficiency turbocharged engines.

"This new system is another important step in our broad based strategy to reduce vehicle fuel consumption and emissions. In order to have a real impact in reducing oil consumption, oil imports, and CO2 emissions, advanced technologies must be affordable enough to drive high volume applications,'' said Wagoner.

He further added, "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 system by GM optimises fuel efficiency and reduces emissions. This is done through the following:

- The engine is turned off when idle
- A more powerful electric motor is used to enhance engine efficiency
- On deceleration, fuel is cut off
- Renewed braking is extended to gain more energy
- Intelligent hybrid battery charging
- An advanced six speed automatic transmission can also be used, dependent on vehicle application.

GM will introduce 8 hybrid models in North America and 9 across the globe, by the end of the year. Over the next 4 years, GM plans to introduce 16 new hybrid vehicles.
