The latestwill take drivers an extra 15.5 miles, thanks to some engineering and software tweaks. Audi of Europe said last Friday the upgrades are all to improve efficiency, but there’s something new for the aesthetics, too, in a new S Line exterior package.
The meat and potatoes of the upgrades reside in the wheel brake and electric motors. Audi said its engineers developed a new wheel brake that minimizes losses occurring where the brake caliper meets the brake disc. Changes to the motor system also see the rear motor power the car almost exclusively, cutting the front motor out of the electricity supply the vast majority of the time. Now, the front motor comes to life when the driver wants more power, and both motors will work in concert just as before. The updates simply keep things more frugal.
Usable range in the battery is up, too, and all of this will take the WLTP cycle range figure to a total of 271 miles. We often say how generous European testing standards are, and this apples-to-apples comparison will underscore it. In the US, the EPA rates the E-Tron to go.
Audi didn’t immediately respond when asked if these updates will make their way to the US-spec model, but it seems highly likely they will. It’s hard to imagine two different wheel brakes for different E-Tron markets, for example.
If they do apply to the US model, the extra 15.5 miles may shrink to reflect EPA testing practices as well.
Other tweaks to the E-Tron include improved regenerative braking and a more efficient cooling system with a pump that uses less power. Audi estimates the regen function accounts for 30 percent of the driving range.
The new S Line package keepshe exterior fresh. We don’t know if there’s an E-Tron with the sporty badge coming, but the S Line package looks the part with a more aggressive front fascia, a spoiler and a rear diffusor. S Line badges are also part of the package, of course. All trims get the buyer’s choice of body color rather than a contrast finish.
European buyers will find the updates available now when ordering an E-Tron.
