What is it? As shown in Los Angeles, Saturn will fit its midsized Aura sedan with the hybrid drivetrain from the current, and next- generation, Vue crossover vehicle. The system is based on a 2.4-liter four-cylinder engine with a four-speed automatic transmission. For this application, the engine is supplemented by an electric motor/ generator and engine-management system to allow for electric energy to be captured for supplementing the engine; to enable the engine to shut down the engine when the car stops and start up quickly when needed; and to create electricity from regenerative braking. Climate controls allow the driver to select a more fuel-efficient "hybrid" mode for air conditioning or a more traditional operation in higher temperatures.
What is new or notable: The Aura Green Line will be available in spring 2007, priced near $23,000.
