About This Item

This SAE Recommended Practice establishes uniform procedures for evaluating conformity between the actual and target drive speeds for chassis dynamometer and on-road testing utilizing standard fuel economy/energy consumption and emissions drive schedules. As vehicle emissions and energy consumption testing expands to include driving on road courses where no “target” speed trace exists, there is motivation to identify metrics which can allow for comparison of results obtained with potentially very different drive traces. This document is revised to accommodate some examples of such metrics that have come into use recently to this end. This version also incorporates necessary changes to include impacts of regen braking on the metrics.
