In 1989, after an extended development process involving 60 designers, 24 engineering teams, 1,400 engineers, 2,300 technicians, 220 support workers, around 450 prototypes, and over $1-billion in costs, the F1 project was completed. The resulting flagship, the Lexus LS 400, had a unique design that shared no major elements with previous Toyota vehicles, with a new 4.0 L V8 gasoline engine and rear-wheel drive. (*)
