NFINITI Motor Company, commonly shortened to just INFINITI, is Nissan's luxury brand, and it has quite a storied history. After years of secretive preparation, the INFINITI brand debuted in the United States in 1989 with the Q45 and the M30. An elite team was formed within Nissan to build a performance luxury vehicle that could challenge other prominent American and European luxury brands. While these vehicles had previously been sold under the Nissan label in places like Japan, the idea was for these luxury models to stand out in the US market.

Because of INFINITI's ties to Nissan, the history of INFINITI, in some ways, starts before 1989. Perhaps the most interesting facet of this is the Skyline. This famous vehicle is the predecessor of INFINITI's Q50 sports car.
