The Cosmo project was started by Mazda in December 1962 . Mazda completed the first two-disc engine prototype in July 1963. The first mobile prototype of the Cosmo Sport was completed in August 1963. This was presented in October 1963 at the Tokyo Motor Show under the title "Project L402A".

The prototype engine L8A had a chamber volume of 2 × 398 cm³. Combined side and circumferential inlets were still used in the L8A. The L8A was developed into the L10A and the chamber volume increased to 2 × 491 cm³. The peripheral inlets were eliminated and replaced with two additional side inlets in the front and end sections of the engine. This improved the torque and drivability at low speeds. The L10A had an engine output of 110 hp (81 kW). The further development, the L10B, had the same chamber volume as the L10A, and the engine output had been increased to 128 HP (94 kW) by changing the timing. The Cosmo Sport accelerated to 100 km / h in 8.8 s and reached 200 km / h.

In April 1966 Mazda manufactured 80 pre-series Cosmo Sport, 60 of which were delivered to dealers in Japan for field testing. Of the first series version with the L10A engine (May 30, 1967 to July 1968), 343 pieces were produced. The second production version with the L10B (July 13, 1968 to September 1972) was built 833 times. Thus a total of 1176 series vehicles (including approx. 1256 with pre-series vehicles) of the Cosmo Sport type were produced. The Cosmo Sport was sold exclusively in Japan . About 36 vehicles were officially exported under the designation "110 S", 11 of them to Europe.
