What Does UDDS Stand For?

UDDS stands for Urban Dynamometer Driving Schedule

The Urban Dynamometer Driving Schedule (UDDS) is a standardized testing protocol used to evaluate the emissions and fuel economy of vehicles under simulated urban driving conditions. It consists of a set driving cycle that replicates typical stop-and-go traffic scenarios, including various acceleration and deceleration patterns. The UDDS is crucial for regulatory compliance and helps manufacturers assess vehicle performance in real-world urban environments.
