Hybrid electric vehicles - micro-hybrids as a step towards lower emissions and fuel consumption

Hybrid electric vehicles - micro-hybrids as a step towards lower emissions and fuel consumption customer demands combined with legal requirements will drive the introduction of hybrid electric vehicle technologies to improve CO2 emissions from passenger cars and trucks. Over the next decade, the technological evolution to counterbalance potential CO2 increase will include engine stop/start operation, as well as new powertrain functions like regenerative braking, shift of engine operating points and various levels of hybrid electric propulsion assist. These functions define the CO2 benefits of hybrid electric vehicles (HEVs) and therefore they can be used to differentiate between four levels of hybridization. Regional differences in driving patterns and competing powertrain technologies will drive a diversification of the hybrid technologies. In North America, Ford Motor Company offers full-hybrid vehicles that answer to market demands. In Europe, the micro-hybrid technology provides an attractive opportunity with respect to system cost versus fuel consumption improvements. For Fiesta passenger cars this enables the implementation of cost effective CO2 reducing technology. For a transit commercial vehicle, it enables low cost of ownership through significant fuel savings in commercial urban delivery applications. This shows that the B-ISG system technology is attractive as a rational and cost effective feature across a wide range of micro-HEV applications (A).
