I don't think the design above would be preferred by Audi in an official season as well. It looks like more of a concept art or something. 

But I'm curious about what they'll do in this sport... Will they enter F1 in a better way than Cadillac you think?

I think they have a potential for that. By the way as far as I know Bortoleto will be one of the drivers. But I don't have any idea about his teammate.
