The feasibility of setting progressive targets for increased fuel economy for new cars, and methods for achieving them is investigated. The need for accurate reproduceable test results following any new legislation is emphasised and reference is made to present UK research in this field. The time required for new engine developments is noted in adopting the new timetable for fuel consumption targets. Aspects of vehicle design considered for possible development include aerodynamic drag, rolling resistance, vehicle weight, transmission, auxiliary drives and engine design. Improved ignition systems and more accurate metering of fuel injected give most promise of increased fuel economy. The motor industry's proposals for a voluntary fuel consumption target, reported in full in an appendix, suggest a 10% improvement on the basic national model average fuel consumption between October 1978 and October 1985. Certain assumptions are explicitly stated in the proposal. Considering progress made in this field since 1973, and that more stringent emission standards are allowed for in the target, the smmt's proposals are recommended. The task for industry in implementing these proposals is considered in another appendix. (TRRL)
