At an announcement at the Indianapolis Museum of Art, the ICONIC committee announced that the 2012 IZOD IndyCar Series will feature Dallara chassis.
Dallara beat Lola, Swift, BAT, and Delta Wing for the bid.
The new chassis will feature aerodynamic body modifications. Dallara will build the monocoque, but the other chassis parts, those visible to the car on the outside, can be developed by other manufacturers. These manufacturers may range from other chassis manufacturers like those who failed in their bids, to presumptive engine manufacturers, all the way to aersopace companies like Lockheed Martin and Boeing.
In effect, this preserves some sort of equality by giving all teams the same basic car with which to start, but allowing other companies to design their own aerodynamic pieces in order to try and develop advantages. Their only limitations are safety testing, the ability for any team to use said parts, and cost limitations - up to $70,000. Teams may use two of these aerodynamic kits per season.
According to Brian Barnhart, the chassis will cost $349,000, but a complete "roller" will cost $385,000 with Dallara's standard aero kit. This is just over half the price of the current chassis. Further, Mitch Murray, governor of Indiana, also announced that the first 28 chassis ordered by Indiana-based teams (the majority of the series) will receive $150,000 discounts.
