Each vehicle undergoes a comprehensive evaluation with over 300 assessments. In addition to performance and handling, our test considers safety and how easy a car is to use in everyday life.

Our overall score is made up of five performance categories. Each includes a large number of assessments. The key aspects are listed here.

Body

  • Workmanship

  • Assessment of all the components and if they add to usability

  • All-round visibility

  • Boot assessment

  • Ease of entry/exit.

Cabin

  • Takes into account the multimedia display and usability

  • Driver controls

  • Space in front and rear

  • Storage.

Comfort

  • Suspension

  • City/urban driving comfort

  • Seat comfort

  • Cabin noise

  • Aircon/heater performance.

Engine

  • Overtaking

  • Acceleration

  • Smoothness

  • Transmission.

Road behaviour

  • Stability

  • Avoidance

  • Steering

  • Brakes.

Range testing

Range testing is undertaken in simulated conditions and builds upon the standard Worldwide Harmonised Light Vehicle Test Procedure (WLTP) that all vehicles must undergo before being approved to be sold in the European Union. The limitation of the WLTP test is that it has more of a town-driving, stop/start bias and only has a short highway component.

The WLTP range isn't so useful for those that spend more time on NZ motorways and state highways. That's why our test has an extra highway element conducted at sustained high speeds. We use this to calculate the maximum expected range, which is the range you can expect to get with a fully charged battery and, for hybrids, a full fuel tank. As vehicle batteries age, the range tends to gradually shorten.

Our car test results are drawn from our European partners who perform independent testing on vehicles in Germany.
