Using a micro-hybrid system featuring carbon/carbon ultracapacitor units as energy storage can result in significant increases in fuel economy over a baseline conventional vehicle, according to a study by Dr. Andrew Burke at UC Davis. All the simulations used powertrains in the same mid-sized vehicle. Burke, 2009.
