Don't want do be disrespectful, but that reads like a Volkswagen press announcement.  You wrote:

" A successful transition for most ICE owners to EVs will only occur when it is virtually seamless."
Obviously true

" Audi is addressing that situation, and part of those design decisions required making the e-tron appear slightly less efficient than the relatively similar Tesla Model X.  "

What does "appear" mean ? Is it less efficient or not ?  And how does lesser efficiency affect "virtually seamless."

Don't get me wrong. The e-tron is a nice package, esp since it is their first car. Audi decided that their car should look like a standard ICE Audi and therefore will be not as efficient as it could be. To counter this they adapted the battery (adding more nickel) so it can charge with higher amps for a longer time, which btw is not the standard use case, since no one has 100kw+ charging at home; well probably someone here on RT has indecision 
To claim victory requires more.
