Additionally, the system provides additional power from the electric motor/generator during launch, when required. At wide-open throttle, such as during a passing maneuver, the system improves acceleration feel by using the motor/generator to bolster the gasoline engine to achieve maximum power.

The new hybrid system also is designed to automatically maintain full accessory functionality, including climate control, when the vehicle is stopped, so that hybrid operation is transparent to the driver and passengers. The Vue Hybrid allows an appropriate balance between fuel economy and comfort by providing a system with two driver-selectable operating modes. An economy mode favors fuel economy by limiting the affect of air conditioning, while the other mode favors maximum passenger comfort and defogging performance.



Three hybrid systems

Saturn Vue Green Line is one of 12 hybrids GM will launch, providing customers with several levels of fuel economy savings at different price points on vehicles ranging from cars to full-size SUVs.

GM launched the world's first hybrid pickup trucks in 2004, with retail availability expanding nationwide with the 2006 model year. GM's all-new, two-mode hybrid system, developed in collaboration with BMW and DaimlerChrysler, is uniquely compact and scalable to vehicles of all sizes. This new system will debut in GM's new, full-size Chevy Tahoe and GMC Yukon SUVs in 2007.
