EV range claims from BYD, Tesla, others scrutinised in new real-world testing

The Australian Automobile Association (AAA) has been testing the fuel consumption and emissions claims of automakers since 2023, and now it’s expanding its testing program to look at electric vehicle (EV) range figures.

The peak motoring body has released test results for five EVs analysed under its federally funded Real-World Testing Program, and found their driving range figures were anywhere between 5 and 23 per cent less than claimed in actual driving conditions.

The AAA says it tests EVs on a 93km route in and around Geelong, Victoria. All were tested in a mix of damp and dry conditions, though temperatures varied from 17°C to 25°C.

It tested a pre-facelift 2024 Tesla Model Y Long Range AWD, a post-facelift 2024 Tesla Model 3 RWD, a 2023 BYD Atto 3 Extended Range, a 2022 Kia EV6 Air, and a 2024 Smart #3 Premium.

Apart from the Smart, which had just 4202km on the odometer, all had between 14,000km and 30,000km on the odometer.

Here’s how the five vehicles compared:

Model Lab range RWT range Lab energy consumption RWT energy consumption
Tesla Model Y 533km 490km 16.9kWh/100km 16.7kWh/100km
Tesla Model 3 513km 441km 13.2kWh/100km 14.0kWh/100km
BYD Atto 3 480km 369km 14.9kWh/100km 18.0kWh/100km
Kia EV6 528km 484km 16.5kWh/100km 16.6kWh/100km
Smart #3 455km 432km 16.3kWh/100km 17.0kWh/100km

The lab range figures are all based on ADR 81/02 claims, published on the government’s Green Vehicle Guide.

ADR 81/02 figures are based on the NEDC test cycle that’s no longer employed in Europe, where it has been replaced by the WLTP cycle that’s considered more realistic.

Likewise, the government’s New Vehicle Efficiency Standard (NVES) still relies on these NEDC-based figures.

Many auto brands in Australia now advertise WLTP figures in their marketing, but the Green Vehicle Guide sticks with NEDC figures.
