Owners of an Audi e-tron from the 2019 or 2020 model years can now travel further on a single charge thanks to a new software update that will extend their car's range by up to 20km.

This latest software was first first rolled out with the premiere of the Audi e-tron Sportback, and brought the range of the Audi e-tron 55 quattro up to 441km on a single battery charge based on the WLTP cycle.

Now, the software features behind this efficiency enhancement are also available for existing vehicles. Among other improvements, the update expands the usable capacity of the high-voltage battery. As a result, the 95kWh battery in the Audi e-tron 55 quattro delivers more net usable power with 86 kWh capacity which translates into increased range.

The software update for all Audi e-tron 55 quattro production vehicles built between mid-September 2018 (model year 2019) and the end of November 2019 (model year 2020) can now be installed free of charge at Audi service partners.
