Increased range for Audi e-tron 55 quattro: software update for 2019/2020 model years
At the same time as the premiere of the e-tron Sportback, Audi rolled out a technology update with improved range for its first electric model series at the end of 2019. As a result, the current model year Audi e-tron 55 quattro can travel up to 441 kilometers on a single battery charge (WLTP cycle). In addition to modified hardware, optimized software was the main factor contributing to the range increase.
As a result, the 95 kWh battery in the Audi e-tron 55 quattro delivers more net usable power – 86 kWh capacity therefore 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.
Efficient motor control, improved thermal management
In addition to the battery capacity, the new software also optimizes the control of the front electric motor. In normal driving mode, the motor attached to the rear axle is responsible for propulsion. For improved efficiency, the front electric motor is now almost completely disconnected and powered off – and only when more power is needed do both motors come into play. This makes it possible to even more effectively exploit the major advantage of the asynchronous motor concept, i.e., currentless operation without electrical drag losses.
The cooling system is the basis for fast DC charging, long battery life, and consistent driving performance, even under high loads.
Excellent suitability for everyday use, excellent sales figures
The success of the Audi e-tron is largely due to its suitability for everyday use. In addition to plenty of interior space and exceptional comfort, it’s the range of the e-tron Sportback 55 quattro and e-tron 55 quattro that plays a decisive role – with ranges of up to 453 kilometers (WLTP) and up to 441 kilometers (WLTP), respectively, longer distances can be covered with ease. The Audi e-tron also stands out for its impressive charging speeds. Ideally, the car needs just under ten minutes at the charging point to achieve a range of around 110 kilometers; the Audi e-tron 55 quattro reaches the 80 percent mark after around 30 minutes. In this context, customers of the e-tron Charging Service can now select from more than 275,000 charging points in 26 European countries.
