Hybrid vehicle test and validation - Propulsion Systems for Hybrid Vehicles - page 541

Note the dramatic effects of small grade and very mild headwind on the power
requirements. The influence of acceleration is very apparent and expected. But the
grade and headwind influence clarify why it is so important to do coast down runs
in both directions on the test track, back-to-back during testing.
