Audi increased the usable amount of the 95-kWh battery pack by 3 kWh compared to the 2019 model, giving all 2020 e-trons 86.5 kWh for regular use. This bump provides a small range increase but maintains a buffer that helps preserve the life of the pack.
The EPA estimates the e-tron Sportback will travel up to 218 miles on a full charge. The EPA also expects it will use 44 kWh of energy for every 100 miles traveled. These range numbers won't grab many headlines, but it'll be more than enough for most owners day to day.
On Edmunds' real-world EV-specific test route, on which we employ settings and a driving style that we think most EV owners will employ, our Sportback test vehicle made it 199 miles on 80% battery charge. An 80% charge is what Audi recommends for daily use. If we had fully charged the battery, we estimate our e-tron would have been able to go about 238 miles. Effectively, we think you can consider the EPA's range estimate to be a little conservative.
Our observed efficiency was 38.2 kWh used per 100 miles. Remember that unlike mpg numbers, the lower the kWh number, the better. For comparison, our testing of a Tesla Model Y Performance resulted in an efficiency of 28.4 kWh/100 miles.
Though most charging will likely be done at home overnight, the e-tron Sportback has DC fast-charging capability. Using a 150-kW charging station, Audi says the e-tron can add about 174 miles of range in just 30 minutes.
