Audi Software Update Increases Range for Older e-tron EVs

Audi Enhances 2019 e-tron Range via Software Update

Audi has released a new software update for its 2019 e-tron electric SUV. This update is designed to increase the vehicle’s battery range by up to 12 miles.

Software Optimizations Improve Efficiency

Although a 12-mile increase may appear modest, it demonstrates the potential of software to refine the performance of existing electric vehicles. Audi achieved this improvement by unlocking additional capacity within the current battery system, effectively boosting its overall efficiency.

The update also incorporates enhancements to the front electric motor and the battery’s thermal management system. These improvements contribute to a more optimized energy usage profile.

Increased Battery Capacity and Range

The 2019 Audi e-tron 55 quattro is equipped with a 95 kilowatt-hour battery. Following the update, the usable capacity is now increased to 86 kWh.

This adjustment extends the vehicle’s range from the original 411 kilometers to approximately 441 km (274 miles) as measured by the WLTP standard. For context, the original EPA estimates for the 2019 model were around 204 miles, a figure generally considered more conservative.

Update Availability and Procedure

The software update is applicable to all Audi e-tron 55 quattro vehicles manufactured between mid-September 2018 (2019 model year) and the end of November 2019 (2020 model year).

Unlike Tesla’s over-the-air update system, Audi requires owners to schedule a service visit to receive this update. This necessitates a trip to an authorized Audi service center.

Keeping Pace with Newer Models

This update allows the older 2019 model to remain competitive with the newer 2020 and 2021 e-tron SUV and Sportback versions. These later models benefit from both improved software and hardware configurations.

Rationale Behind Initial Capacity Limitations

A question arises as to why Audi didn’t utilize the full battery capacity from the outset. Initially, Audi, like other automakers entering the EV market, deliberately limited the usable battery capacity.

This cautious approach was taken to mitigate potential battery degradation over time and ensure long-term reliability.

Industry Trend: Over-the-Air Updates

More automakers are now adopting over-the-air (OTA) software updates, following Tesla’s pioneering example, to enhance vehicle features or improve performance.

In February, Volvo deployed its first OTA software update for the all-electric XC40 Recharge in Europe. This month, Volvo released another OTA update that increased driving range through improvements to the battery management system and pre-conditioning timer.

Furthermore, Volvo introduced a Range Assistant app designed to help drivers maximize the range of their batteries.
