Audi e-tron gets extended range via software update
- The software update for Audi e-tron quattro models of the 2019 and 2020 model years will add 20 kilometers, or 12.4 miles, to the WLTP cycle.
- Audi has tweaked the settings for the cooling system, battery and engine to save energy and unlock more range.
- The Audi e-tron debuted in the United States with a range of 204 miles in the EPA cycle, making it one of the lower-end SUVs on the market at the time.
After three years of production, the Audi e-tron SUV has seen its range increase thanks to a software update. The automaker was able to reduce range in the WLTP cycle by 20 kilometers (12.4 miles) by optimizing thermal management and electric motor behavior. The result is a usable capacity of 86 kWh, compared to 83 kWh.
The most significant change concerns the all-wheel drive system of the twin-engine SUV.
âIn normal driving mode, the engine attached to the rear axle is responsible for propulsion,â notes the automaker. âFor better efficiency, the front electric motor is now almost completely disconnected and turned off – and it is only when more power is needed that both motors come into play. This makes it possible to exploit the major advantage even more efficiently. of the concept of asynchronous motor, that is to say operation without current without losses of electric drag. “
Audi has also tweaked the electric SUV’s thermal management system, which regulates the temperatures of its high-voltage components. The system uses four separate circuits, notes Audi, and engineers were able to reduce volume flow rates in the coolant circuit. The result is less energy consumption, the surplus being retained by the battery.
The changes will be made via a software update, but it will not be a live software update. Owners will need to bring their e-trons to the dealership for these modifications. The good news is that this update will be installed for free.
The update is intended for e-tron quattro models manufactured between mid-September 2018, which corresponds to the 2019 model year, and late November 2019, which corresponds to the 2020 model year. Vehicles manufactured after November of last year had already received the updates during their manufacture, which is why Audi is making this kind of modernization available for older models.
Audi hasn’t confirmed how many extra miles US owners can expect in the EPA cycle because these things aren’t quite apples for apples. But any help with the e-tron quattro’s 204-mile range will likely be appreciated by owners, once the software update is distributed to U.S. dealers for installation.
