Mazda R100


Classics Monthly - - History -

The Wankel pow­ered R100 first broke cover in 1967 at the Tokyo Mo­tor Show as the RX-88 – the RX pre­fix sig­ni­fy­ing Ro­tary Ex­per­i­men­tal. Based on the Mazda 1200, this ro­tary pow­ered medium sized fam­ily sa­loon went on sale in Ja­pan the fol­low­ing year as the Fa­milia Ro­tary and for ex­port mar­kets the car was re­badged as the Mazda R100.

Power came from the same 10A-series twin ro­tor Wankel en­gine used in the 0813-pow­ered Cosmo. The R100’s 0813 en­gine had two in­let ports per ro­tor, with the quad bar­relled car­bu­ret­tor only fu­elling one port per ro­tor under light throt­tle load­ings. In 1973 Mazda re­placed the ro­tary pow­ered R100 with a re­vised model pow­ered by a con­ven­tional 1.2-litre pis­ton en­gine.
