Data Quality and Governance
EVDB maintains a dataset of all fully electric vehicles available. Every effort is made to produce accurate information, and we're grateful to every person that hits the Send Feedback button and alerts us to anything that looks off.
Where our data comes from
Vehicle specs are sourced from manufacturer websites, spec sheets or brochures. When these fall short (missing information), the hunt begins. Sometimes we'll look to overseas sources where the variant and powertrain combo looks to be identical.
Often, sources disagree (sometimes wildly). This is where 'human-in-the-loop' is essential. With the huge rise in fully AI-generated sites and apps, we're seeing lots of confusing data. CLTC range being mixed up with WLTP. Specs being mixed in from other countries and trims. We do our best to verify and cross-check, but it's time consuming trying to get the manufacturers original spec sheet, so thanks again to users who have reported mistakes!
Vehicle statistical data is sourced from NZ Transport Agency Waka Kotahi (NZTA), and registration numbers reflect NZTA's records at the time of publishing. Some data is sourced from MCERT. Data is compiled and improved upon in order to simplify the complexity of NZ's vehicle system.
How we define EV specs
- Weight
- Kerb weight without driver. Note that EU "unladen" figures include a 75 kg driver - this is not kerb weight.
- Width
- Body width without mirrors (with the exception of Tesla, which publishes folded-mirror widths).
- Ground clearance
- Manufacturer figure first - sometimes consulting Australia's ROVER system running clearance as a fallback.
- Battery
- Gross vs usable. Where this is estimated, an asterisk * is appended.
- Boot
- Seats-up vs maximum seats-folded - in VDA where possible, which measures volume in 1 litre blocks. Some OEMs (like Tesla) appear to use the 'water' method, which counts all volume.
- Power
- Combined system output, with launch-control peak where a boost figure exists.
- 800V
- Set only for genuine ~800V architectures, not high charging rates.
- Heat pump
- A very difficult spec to pin down. By heat pump we mean one that heats the cabin, like a reverse air conditioner. Some OEMs use heat pumps for battery thermal management. If an EV does not have a heat pump it will use PTC resistive heater, which is less efficient. Some manufacturers list a heat pump as a feature on a spec sheet, while for others, it is presumed as part of the platform. The heat pump is helpful if you are in a colder area and often need to heat the cabin, (consequently winter range loss is less profound). If you live in a warmer climate, it is less important. Please always check with the dealer.
