Chassis #: RA272F-103
After making its historic debut in Formula 1 in 1964, Honda developed the RA272 for the 1965 season, reflecting feedback from the first season with the RA271. Weight was reduced by more than 5-percent, while the ease of maintenance and setting change were improved, which is a major factor for the F1 circus that goes around the world from circuit to circuit. The body design was also refined to improve engine cooling efficiency.
Further, from the Italian Grand Prix in the middle of the season, a major update was made by lowering the 1.5-liter liquid-cooled 4-st. 60-degree V-12 DOHC 4-valve gear-train engine by 10 cm (3.9 inch) which resulted in a significant improvement in the cornering ability of the machine. At the last race of the 1965 season held in Mexico, the Honda team thoroughly tuned the high-revving V12 engine to comply with the thinner atmosphere at high altitude. On October 24, 1965, American driver Richie Ginther overtook the 2 cars in front during the 1st lap and led the race to the finish to earn the first F1 victory for both Honda and Ginther.
