This procedure incorporates driving cycles that produce fuel consumption data relating to urban, suburban, and interstate driving patterns. The procedure is intended to be used to determine the relative fuel economy among vehicles and driving patterns under warmed-up conditions on a test track or on suitable roads.

This SAE Recommended Practice establishes uniform procedures for evaluating conformity between the actual and target drive speeds for chassis dynamometer testing utilizing standard fuel economy and emissions drive schedules.

This procedure covers measurement of vehicle road load on a dry, straight, level road at speeds less than 113 km/h (70 mi/h).

To define significant driving situations involving acceleration, establish meaningful measures of such accelerations, and develop test procedures that will measure a vehicle’s maximum performance capabilities during those driving situations.

To define a test procedure that when conducted will provide a repeatable measure of a vehicle's maximum acceleration performance.

This procedure covers vehicle operation and electric dynamometer (dyno) load coefficient adjustment to simulate track road load within dynamometer inertia and road load simulation capabilities.

This SAE Recommended Practice establishes uniform procedures for testing electric battery-powered vehicles which are capable of being operated on public and private roads. It is the intent of this document to provide standard tests which will allow various performance characteristics of electric vehicles to be cross-compared on a common basis in specifications, technical papers, and engineering discussions. The tests concern attributes of the total vehicle system rather than those of its subsystems and components. Tests of components such as batteries are the subject of separate procedures. The road tests specified in this document are recommended for use whenever possible particularly to establish vehicle performance specifications. The dynamometer procedures are included primarily to facilitate development testing. Section 3 provides definitions of terminology used in this document.

This SAE Recommended Practice establishes uniform chassis dynamometer test procedures for hybrid-electric vehicles (HEVs) and plug-in hybrid-electric vehicles (PHEVs) designed for public roads. This recommended practice provides instructions for measuring and calculating the exhaust emissions and fuel economy of such vehicles over the following standard test cycles: the Urban Dynamometer Driving Schedule (UDDS), the Highway Fuel Economy Driving Schedule (HFEDS), the US06 Driving Schedule (US06), the SC03 Driving Schedule (SC03), and the cold-start Federal Test Procedure (cold FTP), which is based on the UDDS. However, the procedures are structured so that other driving schedules may be substituted, provided that the corresponding preparatory procedures, test lengths, and weighting factors are modified accordingly. This document does not specify which emissions constituents to measure (e.g., HC, CO, NOx, CO2); instead, that decision will depend on the objectives of the tester.
