As shown in Los Angeles, Saturn will fit its midsized Aura\nsedan with the hybrid drivetrain from the current, and next-\ngeneration, Vue crossover vehicle. The system is based on a 2.4-liter\nfour-cylinder engine with a four-speed automatic transmission. For\nthis application, the engine is supplemented by an electric motor/\ngenerator and engine-management system to allow for electric energy to\nbe captured for supplementing the engine; to enable the engine to shut\ndown the engine when the car stops and start up quickly when needed;\nand to create electricity from regenerative braking. Climate controls\nallow the driver to select a more fuel-efficient "hybrid" mode for air\nconditioning or a more traditional operation in higher temperatures.\n\nWhat is new or notable: The Aura Green Line will be available in\nspring 2007, priced near ,000.
