Boy I can't believe I didn't see that! You had me looking through my training book again... Here's what we were told in class: Real world economy gains around 12%, GM officially claimed economy gains, greater than or equal to 10%, the pie chart is the optimistic one, adding up to 16.5%.
Thanks for catching that!
The Alternator/Starter is a large scale AC alternator very similar to the one pictured in a previous post, just bigger. The only problem with retrofitting this is the need for a 3-phase PWM digital A/C controller to run the thing. And at that the technology seems proprietary in that the rotation sensor (to tell the controller what phase the motor is on) is a bit unique. It produces a double sinusoidal wave, and the controller uses this to interpret the exact position of the motor. BTW, it is a brushless permanent magnet design. That would make this particular system a difficult retrofit.
Back to the original question, that means that the gains from hybrid operation are still 5%, and the gains from the other modifications are 11.5%! Even more reason to incorporate these mods in a conventional malibu/aura.
I'll upload some scans of the system breakdown when I get a chance.
