Revvers

Hot Wheels released Revvers in 1973 and that was the only year they were available. They were diecast vehicles that were slightly larger than regular Hot Wheels and when the wheel located at the back of the car, which was connected to a rubber band, was wound up, they would "rev" along the floor under their own power. There were several models released, including some in two-packs, and there was even one that resembled a camper.
