The VAG's reputation for customer satisfaction is too low for "driving enjoyment" to fit any new marketing slogan, even for an electric car, especially for a VAG electric car. Electronic and infotainment system reliability has been pretty bad since VAG got into those things.
In your case, Fahrvergnügen totally fits,but even if people did remember that slogan, most wouldn't buy it.
VAG is going to have to come up with a slogan, not to get people to remember the past of the 80's and 90's of VW greatness, but to get them to forget the past 20 years and just trust them again.
I'm sure AI can help them with that.
