An optional Mazda Wankel engine was offered and known as the Capella Rotary in Japan or the Mazda RX-2 for export. In addition to the 1.6, a Capella 1500 was added in October 1970. The Capella received a fairly thorough facelift in February 1974. This facelift included a restyled front end (lengthened by 110 mm) and a redesigned dashboard. This model received an optional 1.8-liter (1769 cc) engine for some markets and in Japan it was sold with the "AP" suffix, for "Anti-Pollution". The 1500 was no longer available. The facelift rotary version received the CB12S chassis code rather than S122A.
