Kiichiro Toyoda spent years inside Toyota Industries watching his father Sakichi's automatic loom technology reach commercial scale, and he had a specific conviction: the internal combustion engine represented the same kind of technological transition for mobility that the automatic loom had represented for textiles. He launched the automotive department inside Toyota Industries in the early 1930s and pushed for independent corporate status. Toyota Motor Corporation was incorporated in 1937. The first commercially produced Toyota vehicles were trucks, built during wartime for the Japanese military. Passenger car development began in earnest after the war, with the Toyopet Crown expanding Toyota's ambitions toward private vehicle ownership in Japan. The first attempt to enter the United States market in 1958 with the Toyopet Crown failed — the car was underpowered for American highway speeds and unreliable in American driving conditions. The failure was instructive. Toyota re-entered the American market more carefully, with better-engineered vehicles, and spent the 1960s and 1970s building a reputation for reliability that American manufacturers had not prioritized. The 1973 oil shock created a demand surge for fuel-efficient Japanese vehicles that American automakers had not anticipated. Toyota and Honda benefited. The Lexus brand launched in 1989 with the LS 400, a vehicle specifically engineered to be more reliable and quieter than the Mercedes S-Class it was targeting. The launch defined Toyota's approach to premium segments: engineer to a specific, measurable quality standard, price below the European incumbent, and let the product make the case. By 1997, the Prius had applied the same disciplined engineering philosophy to hybrid powertrains that virtually every major automaker had dismissed as commercially unviable.
