A free software update for Audi e-tron’s from the 2019/2020 model years will allow drivers to travel an additional 12.4 miles on single charge.
Available for a total of 1,655 used Audi e-tron 55 quattro drivers in the UK, the update is now available to UK customers and can be installed free of charge at Audi service centres.
Taking the total maximum range of the e-tron 55 to 286 miles, the software update works by expanding the usable capacity of the high-voltage battery to reduce energy usage between charges.
In addition to the battery capacity, the new software also optimises 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 decoupled and only engages when more power is needed allowing both motors to come into play.
Furthermore the update also improves cooling, allowing the battery and motors to remain closer to their optimal temperatures for longer. The cooling system is the basis for fast DC charging, long battery life, and consistent driving performance, so modifying the thermal control system makes it possible to reduce energy consumption.
“At Audi, we deliver progress through technology – and there’s no clearer demonstration of that than the free software and range update we’ve just launched for our existing e-tron 55 quattro customers,” commented Andrew Doyle Director Audi UK.
As one of the best electric cars currently on the market, the update provides potential used buyers of the Audi e-tron 55 quattro a further incentive to go electric. It also shows that Audi isn’t limiting efficiency increases to new models, but also boosting the efficiency of cars already on the road.
In Norway the model was the best-selling car across all drive types last year, helping Audi’s EV sales grow 51 percent year-on-year.
