In 1960, Toyo Kogyo (Current Mazda) launched its first mass-produced passenger car "R360". The 1960s was an era in which the Japanese automobile industry was developing greatly, and competition intensified, forcing Mazda to seek new ways to survive. Therefore, Matsuda Tsuneji, the president at the time, attempted to put a Wankel rotary engine, which was called "dream engine" into practical use.
The development was started in 1961 with the cooperation of West Germany's NSU, but faced many challenges, including the "chatter marks" problem. The rotary engine was light in weight and small in size, yet high in output and low in noise. It was truly "dream engine", but even the NSU had difficulty developing it. But Mazda engineers never gave up. After much trial and error, Mazda succeeded in developing a rotary engine that could be mass-produced (To be precise, development of composite apex seal) and Cosmo Sport was selected as the memorable No.1 vehicle equipped with a rotary engine.
In the fall of 1963, a prototype model appeared, attracting the attention of car lovers. The Mazda brand and rotary engines have become very famous. Cosmo Sport's styling, which takes advantage of the small size of the rotary engine, has been praised by many as a completely new form of sports car.
The commercial model was announced in 1964, but it took another 3 years to launch. This rotary engine was developed with great care at the risk of the company's future, so failure is unacceptable. If you get into the market in a hurry and become infamous for unforeseen practical problems, may undermine the honor of the rotary engine. Therefore, Mazda repeated the durability test and practical test of Cosmo Sport.
In May 1967, the mass sales model finally went off line. The 982cc 10A (0810) rotary engine delivers 110ps. A total of 343 units of the early model L10A produced until July 1968 were produced and passed on to the later model L10B.
The later model received a lot of feedback from the actual owner and further matured. The wheel base and tread have been enlarged for faster stability. The number of manual gear stages has been increased from 4th to 5th. A large radiator grill has been added under the bumper of the front mask, and air vents have been opened on both sides. The engine has also been improved to 10A(0813) with 128ps performance. A cooler has been set as an option, and safety measures have been added, such as adopting a three-point seat belt and a seat with a head restraint.

It has been famous among the owners of Cosmo Sport for a long time, and is the very early model car number 17 of the late 1968 model. If you say that you still keep your Yokohama single number, some people might know it. The car is actually famous for being the favorite of Ishihara Shintaro (Japanese politician). The license number is the same as before. It is also a legend that Mr. Ishihara, who won the upper house election in July 1968 and made his way into politics, appeared in the Diet with a white Cosmo Sport and was told by Mr. Matsuda, "You don't have to go that far".
This is the best condition for Cosmo Sport that can be obtained now. Restoration is given, but it is highly original and the interior and exterior finish is outstanding. The Apex seal has already been replaced, so you can ride without any problem.
