Hi pete c,
Over the last decade or so there has been an international effort to define a spec for stop-start with regeneration. The standard uses a 42 volt motor-generator, either belt driven or crakshaft, and 36 volt (nominal) batteries. Most car companies either have or are developing such systems. Parts companies Bosch, Continental (ISAD), Delphi, Denso, Gates (EMD), Siemens, Valeo (MArs), Visteon, ZF-Sachs Dynastart (ISG) and others have systems available now. Several cars have had start-stop without regeneration over the last 30 or so years. Building on those systems or starting fresh, Audi, BMW, Honda, Mazda, Mercedes, Toyota and Volvo have cars available this year or next. GM too, trucks for now. It seems like a relatively inexpensive change that provides about 7% improvement in the EPA urban cycle.
