Through the third Era of Honda Formula One challenge, it was the technical trend that the Formula One engines were considered to be one of the elements of entire race vehicle. The engines were carefully designed to have such characteristics as compact size, light weight, low center of gravity and enough stiffness. These characteristics of engines were very important to increase aerodynamic and vehicle dynamics performance in order to reduce lap times on the race tracks. Moreover, Honda engines were always expected to have the highest power output amongst the all Formula One engine constructors.This paper describes how the engines, including the lubricating and cooling systems, were designed from the early stage of development in order to satisfy all demands above.
