It looks like the meeting of the minds has already happened-
even before the auto show?

A concept car to production would take 2 years at least, it looks like Indy cars are either going to be stuck with Dallara (Safety first) or the Delta Wing guys may have a new series started.

I like the older racing cars better and the older American business values.

The thing is unless we have all suddenly become experts on the designs of these cars and can decipher the aerodynamic and mechanical grip numbers, then surely what it looks like is quite irrelevant.
Pretty cars do not always make for good racing and for all we know the ugly third design could be the best racer of the lot; which brings me to my main worry.

There seems to be a few in the racing community that appear to be more concerned about where sponsors are placed as opposed to how the cars race and ultimately that is completely the wrong way to approach any potential chassis design.
If they bring out a car that cannot race well and produces boring events, then regardless of how much space a car has, the sponsorship will be hard to sell, because fewer people may end up watching.

However, if a chassis is chosen that allows exiting and competitive racing where drivers can get close without losing the front end in an aerodynamic wake, then people may be more aroused about the product.
More eyeballs may make marketing the series and obtaining sponsorship a little easier regardless of how cars look.

In regard to multiple chassis, this was asked of Curt Cavin in his “Ask the Expert” column in the Indianapolis Star and at IndyStar.com-I apologize for not knowing how to do links, but you can go to the site as I do daily and see the previous Q and A sessions. Cavin was asked about multiple chassis makers and he says that its his understanding that the constructors are the ones who want to supply the entire field, as they don’t feel they can make enough money supplying 1/2 or 1/3 of the field.
