Prototype for Roadster RF (NDERC-300001 ~), which was solicited for development vehicles online at the end of last yearSports flywheelI did a mounting test.

Since the production model after June 2018 has newly adopted a dual mass type flywheel along with the increase in engine output, our product also needed new development.

Dual mass is a structure in which two flywheels are stacked and an arc-shaped spring is inserted between them.It is a specification that is excellent in comfort and ease of handling by attenuating rotation fluctuations and noise by expanding and contracting the spring.
On the other hand, it is heavier than the general single mass type (single-sheet structure) and is not suitable for sports cars that emphasize accelerator response, but it is a really skillful design that suppresses the moment of inertia to the same level as the previous model. is.
However, as we give top priority to the sense of sport, we want to pursue a more direct feeling and high response.Therefore, we used a single-mass type with a reduced margin for comfort and ease of use, and reduced the moment of inertia by about 30%.We have confirmed the effect even in the test run.

A rare 30th anniversary car for this development!We would like to thank HN "Mr. Beard of the World" for providing us and the cooperation of everyone who applied.

It seems that it can be commercialized around April.Please look forward to it!
