10 Test report

Outlines conditions, principles and test procedures for measuring road performance of partially electrically propelled road vehicles (hybrid). Covers the concept of road performance, which includes speed, acceleration and ability to climb hills. International vehicle categories M1, M2, M3, N1, N2, N3 1) and motor tricycles and quadricycles 2) from the motorcycle types are applicable. Pure electric propelled vehicles are not.
