Hot Wheels are iconic American die-cast model vehicles, first introduced in 1968. Produced by Mattel, they were among the first die-cast models to achieve widespread popularity, known for their speed and stylized designs. Originally conceived as a competitor to Matchbox cars, Hot Wheels later expanded to include a vast range of cars, trucks, and fantasy vehicles. Primarily produced in 1:64 scale, these detailed, high-quality models are now highly collectible.
