Perspective

Tanahashi was hired by Toyota Motor Corporation in 1978, whereupon he was first assigned to the Chassis Engineering Division.[1] There, he worked as a suspension engineer on vehicles such as the rear wheel drive Toyota Mark II, Crown, Soarer, and Aristo, along with the front wheel drive Toyota Corona, Corolla, and Celica.[1] In December 1982 Tanahashi filed for his first U.S. patent, regarding the "upper support structure for front wheel suspension of automobile", which was granted in 1984.[4] His work on the first generation Soarer included a patent for the vehicle's "electronic modulated air suspension";[4] other inventions included a "rack and pinion type steering gear device"[5] and "twin-tube type shock absorber".[6]

In 1992, Tanahashi was transferred to Toyota's Body Engineering Division, where he worked on passenger vehicle suspension architecture, and in 1995 he moved to Development Department 1 of the company's Advanced Vehicle Planning Division to oversee development of new vehicles, platforms, and technologies.[1]

In 2000, Lexus had begun project P280, which intended to create a supercar concept which would showcase 200-mph performance capabilities.[7] In 2001, Tanahashi was promoted to the Lexus Development Center's newly founded Z department, where he was placed in charge of LFA development.[1] The supercar design program opted for a front mid-engine configuration, an approach Tanahashi favored for its combination of dynamics and safety.[3] The vehicle development process was unprecedented in the company's history, exceeding the previous Toyota Supra in performance class, and requiring new engine, cooling, clutch technologies.[3]

Tanahashi's stated goal with the LFA was to produce "ultimate driving pleasure".[3] At the culmination of the development process, Tanahashi remarked in an interview that he was most proud of the car's engine sound, its engine response, and handling.[3] Following the completion of the LFA design program, Tanahashi remained at his current position within the Lexus Development Center.[1]
