EV Model Compare

Compare electric cars side by side

By , editorUpdated How we work out these numbers

Pick two to four cars. Every row is a published figure with its source attached, and the better value in each row is marked. Switch between metric and imperial to see the market figures that actually apply to you.

What actually differs

  • Hyundai Ioniq 6 Long Range RWD goes 60 km further on the observed real-world figure than the Kia EV9 99.8 kWh AWD.
  • On the EPA highway cycle – the one that decides a long drive – Hyundai Ioniq 6 Long Range RWD is rated 95 km further than the Kia EV9 99.8 kWh AWD.
  • Hyundai Ioniq 6 Long Range RWD is 48% more efficient than the Kia EV9 99.8 kWh AWD, which is what the electricity bill follows.
  • Hyundai Ioniq 6 Long Range RWD charges from 10 to 80 per cent 5 minutes faster than the Kia EV9 99.8 kWh AWD.
  • Kia EV9 99.8 kWh AWD carries 22 kWh more usable battery than the Hyundai Ioniq 6 Long Range RWD.
  • Hyundai Ioniq 6 Long Range RWD is 640 kg lighter than the Kia EV9 99.8 kWh AWD.
  • Kia EV9 99.8 kWh AWD is 1 seconds quicker to 100 km/h than the Hyundai Ioniq 6 Long Range RWD.

Every line above is computed from the table below, not written: a difference is only stated where both cars carry that figure from a named source.

How to read this table

EPA and WLTP are not the same test

The same car will show a bigger number under WLTP than under EPA, usually by fifteen to twenty-five percent. That is not one of them lying; they are different drive cycles run at different speeds and temperatures. We show both as published and never convert one into the other, because a converted EPA figure is not a WLTP figure and presenting it as one would be misleading. If a car is sold in only one market, the other row is simply blank.

Real-world range is the row that matters

Official figures are useful for comparing cars to each other under identical conditions. They are not a promise about your commute. The observed real-world row is a mixed-conditions figure from independent testing, and it is usually the number that decides whether a journey needs a charging stop.

Peak charging power is close to meaningless on its own

A car advertised at 350 kW may hold that figure for ninety seconds inside a narrow state-of-charge window. The ten to eighty percent time is what you actually stand around for, and it is the row worth reading. Pack voltage is the useful supporting detail: an 800-volt architecture generally sustains high power for longer and wastes less of it as heat.

What the estimate tag means

Some values cannot be measured, only modelled: what a pack will cost to replace in eight years, what the car will be worth at five, what capacity it will hold at the end of your ownership. Those rows carry an estimate tag, and the methodology page sets out exactly how each one is calculated. Nothing on this site presents a model as a measurement.

Each two-car comparison has its own address, so a pairing can be linked to and returned to. Comparisons of three or four cars work the same way but are left out of search results, because the combinations multiply faster than anyone is searching for them.
