Report on the development of Amendment 3 to GTR 15 on light vehicle emissions. The amendment aims to:

1. clarify phase, cycle and vehicle class terminology to enable interpolation between different levels of downscaling, cycle classes and speed caps (resulting in modifications to WLTC cycle phases and time/speed tables),
2. improve the gear shifting procedures, including changes to gear selection and shift point determination for vehicles equipped with manual transmissions,
3. define the possible and permissible combinations of test vehicle selection and family requirements,
4. define the calculation of the average test mass during road load determination,
5. define single and double roller dynamometers, and
6. make editorial improvements.
