The Honda RA271 was Honda's second Formula One Racing car, and its first to actually enter a race.

The car was developed from the company's 1963 prototype, retrospectively designated Honda RA270. The RA271 made its race debut during the 1964 Formula One season, just one year after Honda started producing road cars, and was the first Japan-built car ever to enter a round of the Fédération Internationale de l'Automobile Formula One World Championship.

Although RA271s only contested three 1964 Grands Prix, driven on each occasion by United States Sports car racing-specialist Ronnie Bucknum, its innovative, Transverse engine, 1.5 L (≈92 cu in) V12 engine – sometimes cited as "the strongest engine of F1's 1.5-litre era"[2] – formed the basis of Honda's race-winning RA272 of 1965 Formula One season at the Mexican GP, driven by Richie Ginther (USA).

Engine dimensions of the 1965 48-valve V12 were 58.1 x 47.0 mm 1,495.28 cc. Convert/bhp @ 13,000 rpm was quoted. This was the most powerful F1 engine of 1965. The engine was safe to 14,000 rpm. Since the 1967 4-cylinder 498.57 cc engine (57.5 x 48.0mm) eventually gave almost Convert/bhp @ 12,600 rpm, the V12 had the potential of Convert/bhp with further development.
