This would come from a tradeoff between going very bold with something that won't have a chance in a million to become the future, or staying very close to the present and showing an iteration on what could be the next year's model.

For context, the Audi TT went out in 1998: https://www.autoevolution.com/cars/audi-tt-coupe-1998.html

Audi was iterating actual products on designs very close I think to seat's concept cars.

Or as I like to call it, the Volkswagen Lupo: https://www.wikipedia.org/wiki/Volkswagen_Lupo
