Current Canadian and United States fuel consumption test procedures and labeling calculations can underestimate the potential real-world benefits of advanced technologies such as stop-start systems. The fuel consumption results outlined in this paper support that point, since the 2-cycle (UDDS, HWFET) test results under-represent the fuel savings when compared to the urban-centered New York City (NYCC) driving cycle and the Japanese 10-15 (J10-15) mode driving cycle when the stop-start system is activated. Vehicles equipped with stop-start systems can use less fuel in urban driving than is apparent from the current published fuel consumption values. The evaluation of off-cycle and real-world testing aims to demonstrate the potential savings of stop-start technology.
