Topper Toys initially produced Johnny Lightning models. Their claim to fame came from their speed — Johnny Lightning cars were incredibly fast compared to other diecast model brands.

The company molded in a small hook beneath the front axle to propel the cars via a lever-driven catapult. The technology achieved faster acceleration than could be obtained by gravity or even "supercharger" devices that required batteries. 

In 1970, Johnny Lightning added 32 fantasy vehicles and several different tracks to their collection. A portion of the new car line up was called "Jet Powered." These cars and trucks were powered by an inflatable bladder encased inside the casting.
