UDDS stands for Urban Dynamometer Driving Schedule, and refers to a driving cycle which represents city driving conditions. The UDDS is used by the United States Environmental Protection Agency to test light duty vehicles on a chassis dynamometer. The results of the test are used to determine vehicle fuel economy and emissions.
The UDDS is also known as the FTP-72 (Federal Test Procedure, 1972) or the LA4. In Sweden it is known as the A10 or CVS cycle, and in Australia as the ADR 27 (Australian Design Rules) cycle.
