Data Sources
Every spec on Cardinkum has a source. Here's where our data comes from. For full methodology, see our About & Methodology page.
Manufacturer Websites
All specifications are sourced directly from official Australian manufacturer websites. We use Australian specs, not global or European specs — they often differ in range, charging speeds, and pricing.
Regulatory & Government Bodies
ANCAP — Australasian New Car Assessment Programme
Independent crash safety ratings for vehicles sold in Australia and New Zealand. All safety star ratings on Cardinkum come directly from ANCAP.
Green Vehicle Guide
Australian government's official source for fuel consumption, CO₂ emissions, and energy efficiency data. Operated by the Department of Infrastructure, Transport, Regional Development, Communications and the Arts.
EV Data Aggregators
ZeCar
Australian EV database and comparison platform. Used for cross-referencing specs and as a secondary verification source. We independently verify any data against primary manufacturer sources before publication.
Verified Australian Owner Reports
Official specs don't always reflect real-world conditions in Australia. Community data from verified Australian owners supplements official figures for:
- Real-world range in Australian conditions (heat, highway speeds, AC use)
- Actual charging speeds at Australian public chargers
- Real servicing costs and intervals
- Software update impacts on performance
All community data is clearly labelled as "Owner Report" and is never mixed with official manufacturer figures. Contributors are verified via email to reduce low-quality submissions.
