Robert Dunham’s Test Run: Mazda Cosmo Sport

“I drove the much-anticipated rotary engine car, the Mazda Cosmo.” I’m still surprised 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 featured 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 Incredibly Flexible Engine

Testing a revolutionary mechanism like the rotary piston engine for the first time can be a very enjoyable and sometimes unsettling experience. However, after test-driving the Mazda Cosmo Sport for about 600km, we found that it had the expected inherent high-speed capability, but also amazingly tenacious power even at low engine speeds, and was flexible enough to withstand use in crowded cities.

Robert Dunham, an American driver living in Japan, test-drove the revolutionary rotary engine Mazda Cosmo Sport. Female race announcer and car enthusiast Noriko Uchida joined him as copilot. Both of them said they were “completely enthralled” by the car, so let’s take a look at their impressions.
