US06

EPA US06 supplemental driving cycle

The US06 is a driving cycle representing high speed and aggressive acceleration conditions. It is used by the US Environmental Protection Agency (EPA) to measure tailpipe emissions and fuel economy of passenger cars on a vehicle dynamometer.

The US06 is part of the "Supplemental Federal Test Procedure" (SFTP), which was developed to test driving conditions beyond those encountered in the standard highway (HWFET) and city (FTP-75) driving cycles. In 2008, the EPA added the US06 and SC03 supplemental tests, as well as a cold FTP-75, to the original city and highway tests for determination of vehicle fuel economy.
