I have been an E-Tron owner for 18 months and have done 26,000+ miles in that time. I use the vehicle for a great deal of 'off road' activities during the winter when I work my three black Labradors (which fit nicely into the boot space). The vehicle is often in fields, on grassy hills or muddy tracks and always holds its own with, or is better than, equivalent SUVs such as Range Rovers and Discoveries. I fit winter tyres and wheels during the months of October to March which means I can go places these other SUVs are reluctant to explore. I can share videos and pictures of where you can take this vehicle off road. I am interested to know if (a) anyone is aware of any sort of plastic under tray to protect the sound proofing felt like material on the under side and (b) if anyone knows just how deep the vehicle can safely wade through standing water. I have so far gone slightly beyond the depth of the axles but with some trepidation.
