Honda RA273
The Honda RA273 was a Formula One racing car used by the Honda team in the 1966 and 1967 Formula One seasons. The engine was re-designed from the RA272's 1,500cc V12 to a brand new 3,000cc V12 due to the change of regulations before the 1966 season. The new engine was designed by Shoichiro Irimajiri.
