From September 1947, Toyota's small-sized vehicles were sold under the name "Toyopet" (トヨペット).[32] The first vehicle sold under this name was the Toyopet SA,[33] but it also included vehicles such as the Toyopet SB light truck, Toyopet Stout light truck,[34] Toyopet Crown, Toyopet Master, and the Toyopet Corona. The word "Toyopet (Japanese article)" was a nickname given to the Toyota SA due to its small size, as the result of a naming contest the Toyota Company organized in 1947. However, when Toyota eventually entered the American market in 1957 with the Crown, the name was not well received due to connotations of toys and pets.[35] The name was soon dropped for the American market, but continued in other markets until the mid-1960s. By the early 1960s, the US had begun placing stiff import tariffs on certain vehicles. The so-called "chicken tax" of 1964 placed a 25% tax on imported light trucks. In response to the tariff, Toyota, Nissan Motor Co. andHonda Motor Co. began building plants in the US by the early 1980s. Toyota received its first Japanese Quality Control Award at the start of the 1980s and began participating in a wide variety of motorsports. Due to the 1973 oil crisis, consumers in the lucrative US market began turning to small cars with better fuel economy. American car manufacturers had considered small economy cars to be an entry-level product, and their small vehicles employed a low level of quality to keep the price low.In 1982, the Toyota Motor Company and Toyota Motor Sales merged into one company, the Toyota Motor Corporation. Two years later, Toyota entered into a joint venture with General Motors called the New United Motor Manufacturing, Inc, NUMMI, operating an automobile-manufacturing plant in Fremont, California. The factory was an old General Motors plant that had been closed for two years. Toyota then started to establish new brands at the end of the 1980s, with the launch of their luxury division Lexus in 1989. In the 1990s, Toyota began to branch out from producing mostly compact cars by adding many larger and more luxurious vehicles to its lineup, including a full-sized pickup, the T100 (and later the Tundra); several lines of SUVs; a sport version of the Camry, known as the Camry Solara; and the Scion brand, a group of several affordable, yet sporty, automobiles targeted specifically to young adults. Toyota also began production of the world's best-selling hybrid car, the Prius, in 1997.With a major presence in Europe, due to the success of Toyota Team Europe, the corporation decided to set up Toyota Motor Europe Marketing and Engineering, TMME, to help market vehicles in the continent. Two years later, Toyota set up a base in the United Kingdom, TMUK, as the company's cars had become very popular among British drivers. Bases in Indiana, Virginia, and Tianjin were also set up. In 1999, the company decided to list itself on the New York and London Stock Exchanges.
