Mach 3

The Mach 3 is a car that was featured only in the 1999 Speed Racer comic book miniseries by WildStorm. It is a 1960s-style Formula 1 race car, and features the same color scheme as the Mach 5, except with a number 3 on it. However, it also features a series of control buttons on the steering wheel, just like the Mach 5.

Controls
The Mach 3 has five control buttons, lettered A through E.
 * Control A - Deploys a powerful defensive shunt from the front of the car.
 * Control B - Just like in the Mach 5, this button, when pressed, allows the Mach 3 to produce grip tires for increased traction over any terrain.
 * Control C - Unknown
 * Control D - Unknown
 * Control E - Deploys a deflective cover to the cockpit, similar to the Mach 5's.

Speed Racer: Born to Race Vol. 1
The Mach 3 was driven in the Del Mar Grand Prix by Hank Racer. When his cousin, Rex Racer, who was driving the Falling Star for Kapetapek, lost control, Hank acted fast and activated the shunt, grip tires and deflector to avoid crashing himself.
