The Mazda Roadpacer AP (Anti-Pollution) is a full-size sedan that was sold by Mazda in Japan between 1975 and 1977, although the last car was not sold until 1979. It was based on the Australian Holden HJ and HX series Premier. Premiers were shipped to Japan without engines or transmissions, and Mazda fitted a 1.3-liter 13B Wankel engine into the bay. The Roadpacer AP has the distinction of being the only General Motors product ever to be fitted for production with a rotary engine. One can be found on display in the Transport World Motor Museum in Invercargill, New Zealand.
