Audi made the claim that the E-Tron would be capable of charging up to 80% in as little as 30 minutes. It was recently spotted using a 155kW rapid charger and the results are impressive. It was able to maintain a 150kW charge for almost the entirety of the cycle, outperforming even whats seen in the Model X. https://electrek.co/2018/12/18/audi-e-tron-155-kw-fast-charge-rate/
