This is the Auto World 1970 Plymouth Hemi Cuda Red Thunderjet HO Slot Car. This is from the Thunderjet Release 28, Class of 1970. These cars are compatible with Auto World, Tomy, and AFX tracks.
The ThunderJet Ultra-G chassis is Auto World’s improved adaptation of the classic "pancake" design, originally developed by Aurora in the early days of electric slot car racing. This is retro slot racing at its best!
