The demographics of the F1000 customer is for sure the issue. If I was smart enough to know the answer, I'd be a Bernie Eccelestone, I suppose !
I'm not sure if the DSR demographics will work in open wheel, F1000. But it might.
What we have in DSR are 'mini' Lemans sports racers with no rules. The quality and technology in the DSR's is like a real Audi or Porsche LeMans car. It's an exciting class to be invoved in - new cars, engines, technology are coming out every week.
F1000 could be like that, it could be a 'mini' Formula 1 car. That would separate F1000 from all the other spec classes and old technology classes. I think F1000 won't succeed if it doesn't stand out big time from all the dozens of other open wheel classes. F1000 will be competing against heavily subsidized open wheel classes, and it has to have something special to stand out. Limiting technology in F1000 may doom the class. Just my thought, I could be wrong.
