A new drive cycle is needed for testing vehicles on chassis dynamometers which is more representative of on-road driving patterns than existing drive cycles to ensure that engines and transmissions are calibrated to achieve 'real-world' reductions in fuel consumption and emissions. Driving patterns from around the world are compared and a suprising consistency is found. Driving patterns measured from trips beginning with cold starts are employed, using randomly selected micro-components of the driving patterns to develop a drive cycle which is representative of the appropriately weighted urban area driving patterns. This cycle is shown to agree much more closely with studies of the driving observed in 16 cities throughout the world than any of the drive cycles applied by the U.S., Japanese or European vehicle testing legislation. Effects on emissions and fuel use are reported.
