I've been using the E-Tron 55 Quattro for the last week for a 100 mile daily commute to Southampton and back. It's averaging 37 kWh per 100 miles. Thankfully I'm still on a cheap deal with Octopus (15p per kWh during the day, 5p at night), so assuming I average at around 10p per kWh (as I charge over the evening and night), it's costing me about £3.70 in fuel per 100m. As opposed to maybe £35 if I was using the (petrol) Maser or Porsche, or £25 if I was using the (diesel) Rangie. (Or around £60 if I braved using the classic V12!)
When I finish my current electricity deal, my Octopus prices are due to move to approximately 35p during the day and 20p at night. Let's say 27p per kWh as an average, given my usual charging schedule. That will mean the 100 mile trip will cost £10. Which is still a good saving, so I'm happy enough with that despite the current energy crisis.
We've had the E-Tron 22 months now and covered 22,500 miles. The real-World range is about 215 miles in the summer, and 195 miles in the winter. We've still never charged it anywhere other than at home. So while we'd not have it as an only car, as a vehicle to do the daily grind of school runs, shopping, modest distance commutes, etc, it's been excellent.
Just thought I'd post this up here as a real-World update/example of our personal experience of EV ownership, in case it's useful to anyone.
