We have photos and details of Swift's proposals for the 2012 IZOD IndyCar Series' next race car. The story inside.

California-based race car designers Swift Engineering have released their proposals for the 2012 IZOD IndyCar Series vehicle.  The Dallara IndyCar chassis is now scheduled to be retired at the end of the 2011 series after nine years of service.

Officials with IRL need a car capable of hitting 235 mph (378 km/h), at a much lower cost than the Dallara's $400k pricetag.  The reduced cost will be an effort by IRL to allow teams to focus more on their drivers and marketing, while a new car could help restore interest in the beleaguered series. 

Aside from the new car, IRL will also be examining proposals for a new engine.  Currently, the series requires use of a naturally-aspirated 3.5-liter 32-valve DOHC V8 made from aluminum alloy.  Honda produces the engine, often criticised as sounding harsh and abrasive, with McLaren providing the engine management system.

Swift is in serious competition for the IndyCar bid.  Other designs are being proposed by Dallara, Lola, and newcomers DeltaWing.  For this car, Swift's partners include Cray, Mark One Composites, and Cruden America.

"Individually, each one of these partnerships is critical to Swift's continuing commitment to motorsport," said Swift chief Jan Wesley Refsdal.  "However, collectively and in conjunction with one another they will help us set new industry standards in innovative design, manufacturing and support."
