We have renderings, video, and details about the DeltaWing proposal for the IZOD IndyCar series racecar. The story inside.

DeltaWing has released a video simulation of their proposal for the next IZOD IndyCar series racecar.  The proposal was introduced at the Chicago Auto Show as Indy Racing League officials contemplate a replacement to the current IndyCar machine.

IRL has had an ongoing relationship with Dallara, whose design was chosen by IRL back in 2003 and will be retired at the end of the 2011 season.  However, aside from getting on years, the Dallara has a high expense for race teams.  IRL has said openly they want the next car to come in at a significantly lower than the current car's $400,000 cost.

However, this is where DeltaWing could have some problems.  With engine, they estimate their cars will sell for around $600,000.

On the other hand, the car would have substantially better aerodynamics, and lighter weight.  This means the car can still hit 235 mph, as IRL officials require, while using a smaller engine.  The company anticipates testing a prototype with a 2.0-liter four-cylinder turbocharged engine producing around 300 horsepower.

The DeltaWing design with an incredibly narrow front end resembles the B-1 Bomber in many ways.  The look is much more interesting than the current IndyCar, weighs half as much, and has 80% of its downforce placed at the rear wheels.

Other designs are being proposed by Dallara, Lola, Swift, and possibly others.  At $600k per car, DeltaWing may have priced their proposal out of contention.
