The first Mazda to bear the Cosmo name (called the 110S) was the first 2-rotor rotary engine powered car. A prototype was introduced at the 1964 Tokyo Motor Show, and 60 pre-production Cosmos were produced for dealership testing in 1965. Full production began in May of 1967 and lasted through 1972, though Cosmos were built by hand at a rate of only about one per day. The Series I/L10A Cosmo was powered by a 0810 two-rotor engine with 982 cc of displacement and produced about 110 hp (thus the 110 name). It used a Hitachi 4-barrel carburetor and an odd ignition design - two spark plugs per chamber with dual distributors. A 4-speed manual transmission and 14 in wheels were standard. The front independent suspension was A-arm/coil spring design with an anti-roll bar. The rear used a live axle with a de Dion tube, trailing arms, and semi-elliptic leaf springs. Power-unassisted 10 in (254 mm) disk brakes were found in front with 7.9 in (201 mm) drum brakes in the rear. Performance in the quarter-mile (400 m) was 16.4 s, with a 115 mph (185 km/h) top speed. The price was lower than the Toyota 2000GT at 1.48 million yen (US$4,100).
