Auto Electronics magazine has good rundown of the mild hybrid system in the Saturn Vue and Aura Green Line models. The system basically functions like a battery powered turbo-charger, providing some extra oomph to the engine when needed. The motor is not connected directly to the drive-line, but does seem to provide some decent improvement in economy, while keeping complexity to a minimum. How close is this system to the one in new plug-in hybrid GM is showing off in a few days? Stay tuned.
