The car is a Radical PR6 2005 model with a 1585cc Hayabusa engine, over 270HP, carbon rear wing, adjustable springs, etc.. Several spare wheels too.
Have more pics and videos upon request. Car was run this year in Sebring and Homestead. The car ran a 2:12 in Sebring, the car is a beast, and you won't find another with a 1585cc engine.
