Audi or Porche could join F1?

I’m not sure if the noses on F1 cars are wide enough to hold all four Audi rings without rendering them miniscule, so it has to be Porsche with the scalable badge. F1 makes more sense for supercar makers so Porsche also makes sense that way. Like you said, Porsche v Ferrari. Bugatti and Lambo are the only other two VW entities that really make sense. Audi generally is a more sensible make so put them in Prototype which looks more like a regular car (kind of). Audi also has the recent Prototype pedigree. Porsche can still run the GT classes which are probably actually a better ad for the street cars anyway. VW makes most sense as an engine maker because via the VW Group you could basically aggregate some great engine people from a variety of their badges, eg, Lambo, Bugatti, Porsche.
