Mazda's Funds Difficult to Stop Developing Rotor Engines

Previously, according to Mr. Fujiwara, head of product marketing and power R&D for Mazda, he said that due to financial difficulties, they will stop the development of Mazda's rotor engines and will concentrate on the research and development of SKYACTIV technology.

Fujiwara said that due to pressure from the international economic situation, Mazda had to reassess some of the current R&D plans in the group. After the assessment, Mazda made a decision to stop the development of a rotary engine and will concentrate on the research and development of SKYACTIV technology.

Fujiwara also stated that the rotary engine as the core technology of Mazda's automotive products will not be permanently abandoned. After the SKYACTIV technology is in the R&D stage and it is on track, Mazda will have sufficient funds to continue to develop rotary engines.

Knowledge supplement:

Rotary engine: Compared with reciprocating engine, the rotary engine cancels the linear motion. The same power of the rotary engine is smaller in size, lighter in weight, and lower in vibration and noise, and has greater advantages. The disadvantage is that the rotor technology is complex, the manufacturing cost is extremely high, and the durability is also lower than the conventional engine.
