It is well known that the fuel consumption of a motor vehicle depends on many factors, including vehicle weight, air resistance, rolling resistance, the type of transmission; the engine size and the engine efficiency. Approaches made in the past to reduce fuel consumption were frequently aimed at improving engine efficiency with show revving, medium displacement engines with a low specific power output. This study is concerned with a different approach, based on relatively small engines with a high specific power output. The study investigates the extent to which modern design features such as multi-valve cylinder heads, variable valve timing, or variable intake systems could be used in engine/gearbox/vehicle combinations to significantly improve fuel economy. The effect of using continuously variable transmissions in conjunction with advanced engine designs is also investigated.
