3 different Dallara concepts

Chassis constructor Dallara has released images illustrating its interpretation of the 2012 IndyCar Series car, based on the criteria set forth by the Indy Racing League.
 
Discussions with league officials have resulted in a much lighter, more efficient car with less drag and more downforce.  The design requires less horsepower to achieve the desired level of performance than its predecessor with greater fuel efficiency.
 
Safety has been improved with increased resistance to frontal lift and improved yaw stability.  Improved raceability also has been addressed in the design with less sensitive aerodynamics in traffic for better overtaking and the reduced incidence of wheel-to-wheel contact.

The cost of the complete package to compete on a variety of racetracks (superspeedway, speedway, short oval, road course and temporary circuits) will be reduced to 55% of the current car cost. Teams will carry much smaller quantities of spares because it requires less parts specific to individual types of tracks, which is another cost saving measure.

The car will be manufactured and assembled in the United States, potentially in the new technology center Dallara is planning to open as part of the Speedway, Ind., redevelopment program, in an effort increase local industry in the area to support the program.
 
Dallara produces the current IndyCar Series chassis, which has been in use since 2003.
 
Quote from Mr. Dallara:
"The new Dallara Indy car will be built in Speedway, Indiana and it will set new standards in terms of safety, fuel efficiency, raceability, technology performance and cost containment.  We can achieve all of these objectives. Dallara as a company, a trusted, credible, stable and loyal partner for the Indy Racing League for the past twelve  years, commits to support, service and develop this new car by locating a dedicated facility near the Indianapolis Motor Speedway”.
