Audi has unlocked more range for its e-tron 55 quattro electric SUV.

A software update for the 2019 e-tron 55 quattro will extend the claimed range of the car by up to 20km, according to Audi.

Europe was first to receive the update, and it’ll be rolled out in the USA soon. Audi Australia says all vehicles delivered in Australia are 2020 builds, and were fitted with the newer software at launch.

Owners in Europe and the USA won’t be able to download the update over-the-air, it instead needs to be installed by a dealer.

The update unlocks more range in a few ways. For starters, it unlocks more usable capacity in the lithium-ion battery pack.

Although the e-tron 55 quattro has a 95kWh battery pack, some of that capacity can’t be accessed by the driver to preserve the life of the battery pack.

The update means less of the lithium-ion battery is cordoned off, freeing up more range.

The update changes how the active battery cooling system works for greater efficiency. It also means the front motor can be switched off completely now, making the car more efficient at a cruise or under light throttle inputs.

Software updates extending the range of electric cars are becoming more common.

Volvo and Polestar recently announced an update to free up more driving range in the Polestar 2, and Volvo C40 and XC40.

The brand says a wireless update to the electric SUV brings smarter battery management and regenerative braking, which helps the XC40 go further on a charge in the real world. Volvo hasn’t released an updated range figure, however.
