The Hot Wheels Pepsi Challenger is from 1982. Based on the Plymouth Arrow funny car driven by Don “Snake” Prudhomme, the casting was originally released in 1978 as the Army Funny Car and again in 1979 as the Human Torch. I scored this Malaysian variation with the snake on the hood on eBay.
Another Malaysian variation had no snake on the hood. This one was given to me by my friend Randy.
