Green Technology

At the Los Angeles Auto Show,.General Motors shares its intention to produce a Saturn Vue Green Line plug-in hybrid that has the potential to achieve double the fuel efficiency of any current SUV, utilizing plug-in and two-mode hybrid technology.  The Vue will have robust electric-only capabilities and Lithium Ion battery storage.    ...

... "This hybrid SUV will use a modified version of GM's 2-mode hybrid system and plug-in technology, a Lithium Ion battery pack when ready, highly efficient electronics and powerful electric motors to achieve significant increases in fuel economy. A plug-in hybrid-electric vehicle differs from non-plug-in hybrid-electric vehicles by offering extended electric-only propulsion, additional battery capacity and the ability to be recharged from an external electrical outlet. The Saturn Vue Green Line plug-in hybrid is expected to offer electric-only propulsion for more than 10 miles. At higher speeds or when conditions demand it, such as brisk acceleration, a combination of engine and electric power or engine power only will propel the vehicle.

In addition to plug-in capabilities and the modified 2-mode hybrid system, the Saturn Vue Green Line hybrid SUV's powertrain will feature Lithium Ion battery technology, two interior permanent magnet motors and GM’s 3.6L V-6 gasoline engine with direct injection. When ready for production, the Lithium Ion energy storage system will be replenished when the battery charge is depleted to a specified level by utilizing the 2-mode hybrid system’s electric motors and regenerative braking systems. When the vehicle is parked, the battery can be recharged using a common household exterior 110-volt plug-in outlet.

The 2-mode hybrid system will be altered for use with plug-in technology. It maintains two driving modes – one for city driving, the other for highway driving – and four fixed mechanical gears to maximize efficiency while maintaining performance. In addition, special controls will be utilized to enable higher speeds during electric-only propulsion and maintain electric-only propulsion for longer periods of time. " ...
