Hot Wheels

Hot Wheels is a brand of 1:64, 1:43, 1:18 and 1:50 scale die-cast toy cars introduced by American toy maker Mattel in 1968. It was the primary competitor of Matchbox until 1997 when Mattel bought Tyco Toys, then-owner of Matchbox. Many automobile manufacturers have licensed Hot Wheels to make scale models of their cars, allowing the use of original design blueprints and detailing. Although Hot Wheels were originally intended for children and young adults, they have become popular with adult collectors, for whom limited edition models are now made available.

History

1968

Hot Wheels were conceived to be more like "tricked out" cars as compared to Matchbox cars which were more city or "real life" cars. There were sixteen castings released in 1968, eleven of them designed by Harry Bentley Bradley. The first one produced was a dark blue Custom Camaro. Bradley was from the car industry and had designed the body for the (full-sized) Dodge Deora concept car and the Custom Fleetside, (based on his own customized 1968 Chevrolet C-10 Fleetside).
