how does lexus ensure the high quality of every lexus vehicle
The first Lexus vehicles were manufactured in Toyota's Tahara plant, a highly sophisticated, computerized manufacturing plant in Japan. Lexus production techniques include methods and standards of quality control that differ from Toyota models. At the Tahara plant, separate assembly lines were developed for Lexus vehicles, along with new molds and specialized manufacturing equipment. Welding processes, body panel fit tolerances, and paint quality requirements are more stringent. Lexus plant workers, typically veteran technicians, are identified via repeated performance evaluations and ranked according to skill grade, with limited applicants accepted. The highest level takumi (Japanese for "artisan") engineers are responsible for maintaining production standards at key points in the assembly process, such as testing engine performance. Production vehicles are given visual inspections for flaws, individually test-driven at high speeds, and subjected to vibration tests.
