Description / Abstract:
This procedure covers measurement of vehicle road load on a dry,
straight, level road at speeds less than 113 km/h (70 mi/h).
Purpose
This SAE Recommended Practice provides uniform testing
procedures for measuring the road load force on a vehicle as a
function of vehicle velocity and for simulation of that road load
force at 80 km/h (50 mi/h) on a hydrokinetic chassis dynamometer.
For application to electric dynamometers, refer to SAE J2263.
