The most efficient EVs in Australia

An efficient electric vehicle is the one that uses the lowest amount of electricity to travel the furthest distance.

"But I get less than this when I'm driving" - see below for the differences between WLTP consumption and efficiency on your dashboard.

This list is updated dynamically as new models are released.

To compare EVs with each other, the WLTP consumption rating (Wh/km) is used. This measures recharged electric energy from the mains on a standardised cycle.

So if your EV has 189 Wh/km it means it will cost you 18.9 kWh of electricity (from the mains) to travel 100 kilometres.

What you see on the dashboard (efficiency) shows the amount of energy used from the battery. Most EVs have a temperature sweet spot (20-25°) where energy use is lowest.

However, WLTP consumption allows you to estimate true running cost. Electricity does not go directly into the battery - there are loss; thermal loss, the AC-to-DC conversion, and some EVs may use mains electricity to precondition the battery.

Two different units

Dashboard efficiency is given in two different units:

  • kWh per 100 km (how many kilowatt-hours are consumed per 100 kilometres
  • km per kWh (how many kilometres the car travels per kilowatt-hour

It's just a personal preference, and in many cars you can change the setting.

What makes an EV efficient?

All the usual suspects:

  • low aerodynamic coefficient (the smaller the frontal area the better).
  • low mass.
  • powertrain efficiencies.
  • low rolling resistance.

So, generally, sedans, and lighter hatchbacks will be the most efficient EVs.
