The paper examines the incentives for energy conservation in vehicle design and construction, and in particular, factors aimed at reducing fuel consumption such as weight reduction, power train efficiency improvement and reduction in aerodynamic and rolling drag. Details are given of development work at Bl Technology aimed at energy conservation which resulted in the 115 mph ECV 3 development vehicle designed for minimum whole life cost, an average fuel consumption of over 50 mpg and a performance equal to current medium-sized cars in terms of ride handling, vibration and safety. Details are given of energy saving features of the design such as lightweight aluminium body structure, aerodynamics, weight-saving wheels and power-train efficiency. A three-cylinder aluminium engine of 1100 cc, of 10.5:1 compression ratio was used with a gearbox featuring automatic selection of 4/5th gear. Future transmissions will incorporate a continuously variable systems to allow optimum engine operation. (TRRL)
