These two jet powered semi trucks are each powered by enormous Pratt & Whitney J34-48 jet engines! The truck in the background, called "Super Shockwave" is built on a 1957 Chevrolet cab while the one in the foreground, called "Shockwave" is a Peterbilt semi.
The Shockwave holes the world record for a jet powered semi truck at 376 MPH! Just watch these things race each other!
