A software update will add up to 20 kilometers (12 miles) of range
The update improves the motor control and the thermal regulation of the battery
Around 34,000 vehicles world wide can be updated.
Audi is announcing a new software update that will improve the efficiency of its e-tron 55 Quattro enough to add around 20 kilometers (12 miles) to its range.
This update is installed from the factory on every new e-tron SUV, but it will also be available to owners of 2019 and 2020 model year e-tron 55 Quattro, the version of the vehicle equipped with the 95-kWh battery.
According to the company, 34,000 vehicles worldwide built between mid-September of 2018 and the end of November 2019 are now eligible for this software update that can be installed free of charge at any Audi dealership. The Sportback version of the SUV is also included.
Changes made by this update are broad and they include an increase capacity for the 95-kWh battery, that now provides up to 86 kWh of useable energy.
Revised motor control logics improve the electricity consumption by disconnecting the front motor in normal driving, only sending power to it when all-wheel drive is needed. This is made possible by the use of asynchronous motors that can be turned off without causing electrical or mechanical drag.
Modifications to the battery’s cooling system are also included in order to improve fast-charging times and lower the amount of electricity used by the system itself.
This is very good news for owners of 2019 and 2020 Audi e-tron 55 Quattro vehicles because it means their car will depreciate a lot less because it will feature the same drivetrain technology as the new ones that are currently being built.
