Immediately after 3 several years in output, the Audi e-tron SUV is having a vary maximize thanks to a computer software update. The automaker has been in a position to squeeze out 20 kilometers (12.4 miles) of range in the WLTP cycle by optimizing thermal administration and electric powered motor behavior. The consequence is a usable 86-kWh potential, up from 83 kWh.

The most considerable adjust considerations the all-wheel-travel procedure in the twin-motor SUV.

“In normal driving method, the motor attached to the rear axle is liable for propulsion,” the automaker notes. “For improved efficiency, the entrance electrical motor is now just about wholly disconnected and run off—and only when much more power is needed do both motors arrive into participate in. This tends to make it feasible to even much more efficiently exploit the major advantage of the asynchronous motor thought, i.e., currentless operation without having electrical drag losses.”

Audi has also tweaked the thermal management procedure of the electric powered SUV, which regulates the temperatures of its large-voltage factors. The method uses 4 different circuits, Audi notes, and engineers have been capable to decrease the volume stream premiums in the coolant circuit. The outcome is reduce power intake, with the surplus staying saved by the battery.

The improvements will be built by way of a program update, but it will never be an more than-the-air software update—owners will need to take their e-trons to the dealership for these improvements. The great news is that this update will be mounted for absolutely free.

The update is intended for e-tron quattro styles created concerning mid-September 2018, which corresponds to the 2019 product yr, and the conclude of November 2019, which falls on the 2020 design year. Motor vehicles built after November of final 12 months had currently received the updates through their manufacture, so Audi is making this retrofit of kinds available to older types.

Audi has not verified just how numerous additional miles of variety US entrepreneurs can be expecting in the EPA cycle, as these matters aren’t fairly apples to apples. But any assistance for the 204-mile array of the e-tron quattro will in all probability be appreciated by the proprietors, as soon as the software program update is distributed to US dealerships for set up.
