The DeltaWing has been an interesting experiment to watch evolve. It started out as just a test in the 2012 24 Hours of Le Mans to see if such a radically different design could actually be competitive on the track. It has kept racing though and entered its second season of racing in the US this year. DeltaWing Technologies Inc. is now taking the next big leap in the racecar's tech with a four-seat roadcar concept (pictured above).
