The Audi Q8 e-tron is powered by a 114 kWh battery, of which 106 kWh is usable. This is true for the 55 e-tron variant and the performance SQ8 e-tron variant, while the 50 e-tron variant has a smaller battery. Previously, the Audi e-tron was powered by a 95 kWh battery pack, of which 86.5 kWh (formerly 83.6 kWh) was usable. It can be charged from zero to 80% in around 30 minutes using 150 kW DC fast-chargers. For home charging in the EU, a standard 11 kW charger recharges the pack in 8.5 hours, while an optional 22 kW charger halves this time. In the US, a 40A 9.6 kW J1772 charger is supplied by Audi, but 11 kW can still be achieved using a 3rd party 48+ amp J1772 charger. A thermal management system (also serving the motors and power electronics) keeps the battery between 23 and 35 degrees Celsius, and battery modules (twelve 60 Ah cells each) can be replaced. The car uses an energy recuperation system that, on average, contributes 30% to the range. Recuperation can be achieved both when the driver releases the accelerator and when applying pressure to the brake pedal. The e-tron also sits slightly lower than a traditional SUV; at high, it is lower than the
Audi Q5. It has of boot space, more than the
Mercedes-Benz EQC, along with of storage space in the front. The real winter range drop might be slightly higher, because in the aforementioned tests the "winter" car had the advantage of more aerodynamic wheels than the "summer" car. This stands well in comparison to other EVs. Five other electric vehicles, including the 2017
Tesla Model S 75D, were tested at the temperature of with cabin heating on, and all of them had a range drop of at least 30%, and 41% on average (compared to when the temperature was and cabin heating/air conditioning was off). The e-tron is, in summer driving, less efficient than the Tesla Model X in terms of distance covered per kWh of energy. The e-tron is less affected by low temperatures, however, so driving in the winter brings the results of these two vehicles closer. In a test done at temperatures in the range and including high-speed highway driving, the e-tron's efficiency was about 12.4% worse than in the Model X. In slightly below-freezing conditions, the difference was smaller and the e-tron's efficiency was only about 8.6% worse than in the Model X.
Charging The e-tron Audi of America is more cautious with their estimates, saying that of range can be added in 10 minutes when using a 150 kW charger. At 90%, charging rate is about 82 kW and it remains above 50 kW until reaching 100%. Using a 50 kW charger, the car can be charged at a constant rate of 50 kW, up until reaching 100%. In 2022, with the introduction of a larger battery (and the renaming of the vehicle, which is now known as the Audi Q8 e-tron), the charging speed was increased to 170 kW (150 kW in the low-end variant).
