I think there may be a benefit to having normal electrolytic capacitors in a car, as the ripple from the alternator is substantial and you could smooth it out with capacitors, possibly improving efficiency? Depends on how the regulator circuit works, but if it doesn't measure RMS voltage correctly then this would be useful.

The way I see it, the primary use of ultracapacitors is to take load off the battery for starts as they have much higher power density than batteries.
Thanks
Just for some clarification (4 myself)....The post with the youtube by lasersaber is dated. He used RC lipo battery/maxwell ultracaps. and has made no current posts...
As I have early stated voltage stabilizers are sold on ebay from 40-200 plus dollars.
Can someone further my understanding of series/parallel in relation to a bank of capacitor Example battery in series increase voltage and battery parallel increase the ah/amp hour
