Mach 4 (WildStorm)


 * For other uses of "Mach 4", see Mach 4.

The Mach 4 is a vehicle featured in the 1999 Speed Racer comic book series.

Background
Eight years after Rex Racer died, Dr. Bent Cranium and Henry Racer develop the ER-X, a powerful racing engine that would serve as the predecessor to the infamous GRX. The engine is given to Pops, who installs it into the Mach 4, with Hank Racer as the test driver.

Buck Condor, who sought to steal the engine technology for his own selfish gain and having tried to buy Pops out, sabotaged the test run by damaging a brake line on the car, resulting in a crash that paralyzes Hank from the waist down.

Johnny Lightning
A limited edition diecast toy car of the Mach 4 was produced in 2000 as part of the Johnny Lightning toyline. It was only available by mail order. It could be acquired by sending in $3.99, $3.95 S&H fee, and two proofs of purchase (either two UPC codes with complete cardboard backing or cash register receipts).

The diecast car itself is a repaint of the Mach 5 in red with a white "M" in contrast to the white body and red "M". Along with that, the headlights are painted on top of the Mach's side-noses. Along with that, it has a black number 4 in a white circle with a thick black outline.

The Mach 4 is one of the most coveted Speed Racer diecast cars in the Johnny Lightning series, often fetching high prices on the internet.

Trivia

 * The ER-X engine used by the Mach 4 in the WildStorm/DC comics is named in reference to the GRX's original Japanese name in the manga.
 * The engine is compact in size yet capable of torque figures up to 16,000 RPM, providing acceleration described as "motorcycle-like".
