Buy a 2022 E-Tron GT or RS E-Tron GT and get free DC charging with Electrify America ( 2 years with Electrify Canada). 30 minute sessions should provide 290kms of range with the E-Tron GT Source : Audi e-tron GT owners to get 2 years of free fast-charging with Electrify Canada - Drive Tesla Canada
I have a 2019 E-Tron and EA says it comes with 1000 kWh free charging at EA chargers. I was unable to convince the car I was the "Key Owner" and finally gave up and joined EA for the 150 kW charging. First charge at the local EA charger was 50 kW, not the 150 I joined for... EA claimed it was a possible unit issue and wrote it up for service. I would not own an electric without home charging, too much broken public chargers, and problems with getting charged as expected.
Back from another trip with four Electrify America charging events, all with the promised +100 kW charging rates. But every charge required a phone call to EA instead of being a member using the phone app. I spent 15-20 minutes getting set up and 17 minutes charging for the 2019 Audi E-Tron each time. The EA person suggested I had not properly shut down the app one time. An app that can't tell time and turn itself off?? I love the fast charge but could do without the blood pressure spike each time. And yes I beg them to just send me a plastic swipe card each time, like the other charging companies use.
RFIDs have always worked flawlessly for me, helping others using "failed communication apps" sometimes helps.
