The AIR Index – Methodology Infographic

Every AIR Index rating requires at least two cars of the same type to be tested at least three times, recording at least five x 10km trips, which each take approximately 20 minutes per trip.

Each car is independently tested in accordance with a voluntary standardised European protocol CWA 17379.

This infographic shows a high level view of the methodology used by AIR when testing vehicles for rating in the AIR Index.
