The car is red with two white racing stripes running down the middle. Just as Rex had crossed the finish line, he loses control of the car due to his lack of experience and overconfidence, and crashed. When Rex was 18 years old, he entered a race without asking Pops' permission and used the car for it. It had only appeared in a flashback sequence in part 1 of the two-part episode " Challenge of the Masked Racer", where Pops told the story of how Speed's older brother, Rex, ran away from home years before the events of the series. It is an unnamed race car that Pops Racer had spent years building.

The name would not appear until 2000's release of Speed Racer presents Racer X Vol. PLEASE NOTE: This car was not named the Mach 1 outright nor was it ever given that name during production. 2 WildStorm/DC Comics: Speed Racer presents Racer X Vol.
