The Aura Green Line is equipped with the affordable GM Hybrid system, which reduces fuel consumption via sophisticated controls and a unique electric motor/generator mated to a 2.4-liter Ecotec VVT four-cylinder engine and Hydra-Matic 4T45 four-speed transmission. This innovative hybrid powertrain is rated at 164 horsepower at 6400 rpm and 159 lb.ft. of peak torque at 5000 rpm. While maintaining the vehicle's sporty feel, the GM Hybrid system seamlessly reduces fuel consumption by:

• Shutting off the engine when the vehicle is stopped, to minimize idling
• Enabling early fuel shut-off during vehicle deceleration
• Converting vehicle kinetic energy to electrical energy through regenerative braking to charge the advanced nickel metal hydride battery
• Performing intelligent battery charging when it is most efficient
