Yukihiko Yaguchi

is a Japanese automotive engineer and designer responsible for the design of the first generation Lexus IS F. Born in 1955, he has over 30 years of experience in car design, having worked as head of development and planning for Lexus, where he holds the title of chief engineer. His involvement with Lexus and Toyota is likely how the SC 300 received the renowned inline-6 2JZ-GE from the Mark IV Toyota Supra in a naturally aspirated format. Yaguchi previously worked on the development of the Toyota Chaser and all generations of the Toyota Supra.

Early life

Yukihiko Yaguchi was raised by the Japanese tradition, which is very traditional and strict. At the Tokyo Metropolitan Institute of Technology he studied Mechanical Engineering but did not specialise in a subject. However, long before he studied mechanical engineering it was obvious to him that he would work for the Japanese automobile industry. At TMC (Toyota Motor Company) he found his first job. Yaguchi joined TMC in 1977.

While he designed the Supra Yaguchi-san was at the 1980s birth of Lexus as a part the TMC. He spent a lot of time with the new designs for Lexus cars (especially Lexus LS 400) and became head of general development and planning for Lexus. In an interview, he said that he loves sports cars, but thinks it's a pity that the most sports cars have 2 seats instead of 4. Exactly that idea was the basis for the IS F.
