Steady evolutionary improvements have turned open-wheel race cars, like those in the Indy Racing League, into the amazingly fast machines they are today. The Delta Wing Concept shown at the 2010 Chicago Auto Show ignores evolution in favor of full-on revolution.

While we wait for its debut please watch this video explaining some of what we can expect from the Delta Wing Concept.
