Hot Wheels

Hot Wheels (abbreviated as HW) 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 May 18, 1968. It was the primary competitor of Matchbox until 1997, when Mattel bought Tyco Toys, then-owner of Matchbox.

In 2018, Hot Wheels celebrated the making of its four billionth car with the production of a diamond-studded model worth US$140,000. It had 2700 diamond chips, a total of almost 23 karats, and was cast in white gold, with rubies serving as taillights.
