A properly implemented system would to some extent improve fuel economy and power as well as conserving brake pads. Someone would need to do the calculation to determine whether these effects would be measurable or it is just marketing guff  |
Agreed. I am wondering if designing such an alternator would be tricky though. Any electrical engineers reading this?
