A fleet of 50, 1986-1987 model year cars designed for unleaded gasoline has been tested on the road and on a chassis dynamometer over 5 driving cycles and a wide range of other manoeuvres including steady speeds. It was found that the fuel consumption of this fleet was 17 to 23 % (depending on test cycle) less than that of a corresponding fleet to leaded fueled cars of 1980 model year average. Exhaust emissions were significantly lowered in the range of 45 to 93 %. However trend line analysis of the several data sets indicates that the ULG, fleet has about 6 % higher fuel consumption than would have been expected if there had been a continuing evolution of leaded vehicle technology. The data base produced has applicability to a wide range of planning and design tasks, and those illustrated indicate the effects of speed limit changes and advisory speed signs on fuel consumption and emissions.
