Star ratings
How star ratings are assigned
A six star rating system is used for each category. The more stars the better the vehicle.
The process of assigning star ratings first requires vehicles to be ranked based on their test results, adherence to standards or design features. This gives an underlying ranking of vehicles that then needs to be set in the context of what’s being driven and/or is available for sale in New Zealand.
In general, star ratings attempt to reflect the position of a model relative to the vehicle fleet in New Zealand. As such the rules that translate rankings into ratings may be re-assessed from time to time.
Detailed pages describe how the star ratings are calculated for fuel economy, driver safety, others’ safety, carbon dioxide (CO2) emissions and air pollution.
