The Baja Bug was designed by Larry Wood. It is based on a Volkswagen Beetle modified for off-road desert racing, a very popular and real-world modification known as a "Baja Bug."
This specific casting of the Baja Bug debuted in 1984. The model 5907 is from the 1983 "Real Riders" series (though typically listed with a 1984 release year). This is one of several Baja Bug castings Hot Wheels has made.
This casting features a significantly modified Beetle body, with cut-away fenders and a large, exposed rear engine. The 1983/84 Real Riders version came in white with yellow and orange stripes and featured rubber Real Riders tires with a knobby off-road tread. It has a metal body and chassis.
Hot Wheels has a long history with the VW Beetle. This casting is distinct from the original "Custom Volkswagen" from 1968 and the more recent "Baja Beetle" castings. It is also different from the "Baja Beetle" that was part of the original "Spoilers" series.
The mainline version released in 1984 was yellow. It has been released in many colors, including red, blue, and black. A notable variation is the 1987 version with "Construction Tires" (CT).
