Aura Green Line: GM's hybrid cost cutter

Saturn's hybrid sedan costs less than other hybrid cars, but it's not worth as much either.

Saturn Aura Green Line: Stopping
The Aura Green Line has a simple "mild hybrid" system that uses the electric motor to assist the gasoline engine without directly driving the car's wheels.
Saturn Aura Green Line: Stopping
It's impossible to coast in the Aura Green Line. As soon as you lift your foot off the gas pedal, the car downshifts. Fuel to the engine is cut off while the transmission remains in gear, and the car automatically steps down through the gears as the car slows.

There are two reasons for this: First, since the engine isn't getting any fuel it would just konk out if it weren't being pushed along by the transmission.

Second, the Aura's electric motor/generator isn't connected to the wheels. It's connected to the engine. To spin the motor/generator that makes electricty to charge the battery (instead of using electricity help move the car) you have to push the engine. It's all locked together.

As hard as General Motors' engineers have tried to make all this downshifting seem smooth and transparent, it still feels like uninvited interference with your attempt to smoothly slow and stop the car.
