Robert Dunham’s Test Run: Mazda Cosmo Sport

“I drove the much-anticipated rotary engine car, the Mazda Cosmo.” I’m still surprised to be able to say these words. This is a test-drive report of the Mazda Cosmo, published for the first time.

Recently, I was invited by Toyo Kogyo’s president, Tsuneji Matsuda, to visit the company’s factory and test track in Hiroshima, as reported in the Asahi Evening News. There, believe it or not, I had the opportunity to test drive the Mazda Cosmo, Japan’s first rotary engine car. It was a truly enjoyable and valuable experience for me.

An Astonishingly Flexible Engine

There is something both exciting and faintly unsettling about testing a revolutionary mechanism for the first time. This was certainly the case with the rotary-piston engine. However, after approximately 600km behind the wheel of the Mazda Cosmo, it became clear that this remarkable powerplant combines outstanding high-speed performance with astonishing flexibility at low engine speeds. Even in crowded city traffic, it proves entirely practical and capable of everyday use.
