What is the Mach 4 exactly?

Asked by kapuerajam (917points) April 18th, 2008 from iPhone

I know about the Mach 5 in speed racer but yestarday I was looking at the back of my Hot Wheels box and I saw it and was wondering if it is the car that Speed’s brother (racer x) wrecked when Pop built his first car.
