To define a test procedure that when conducted will provide a repeatable measure of a vehicle's maximum acceleration performance. This SAE Recommended Practice provides a standardized means of measuring acceleration performance of passenger cars and light-duty trucks.

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

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.

This procedure is a modification of the urban driving cycles noted in SAE J1082 and which is run on a suitable road or test track. The procedure yields cold start/warm-up fuel economy values indicative of consumer level at the ambient condition of the test. Within referenced limitations, the procedure can be utilized to determine the fuel economy differential among vehicles or between vehicle changes. Purpose This SAE Recommended Practice provides a uniform test procedure for measuring the fuel economy of light-duty vehicles during cold start and warm-up operation (motor vehicles designed primarily for transportation of persons or property and rated at 4500 kg GVW (10 000 lb) or less) on suitable roads.
