Improving battery power to such as level would further enable hybridization to near-HEV levels as well as engine downsizing, thereby enabling fuel economy improvements beyond the current 10-15% MHEV limit. Accessories that are typically powered via hydraulic power or the serpentine belt may be converted to electrical power.
