The idea of using the Wankel rotary engine as a range extender for future Mazdas has always been highly suggestive. An iconic engine coupled with the search for autonomy and connected to the environment through the model MX-30: it could not have been better in terms of image for the Japanese brand.
However, this dream is to be put aside indefinitely: according to the Mazda spokesperson Masahiro Sakata, the company is still evaluating the use of the engine as a range extender, but this will not happen in the first half of 2022 as originally planned.

As reported by Automotive News now the introduction time of the press as an extender is “uncertain”. Basically it is still in the studio, because Mazda does not want to abandon it; but the timing could be so vague as to have convinced the company to stop making an announcement until a more outlined plan. According to the Japanese press, the Wankel would be complicated to use due to the presence of a large battery that would be mandatory to use to make the system efficient. The downside would therefore become the cost of the vehicle.
Hybrid and plug-in hybrid engines with rotary should instead be unveiled between 2022 and 2025; as mentioned, the wankel would be a generator, in the same way the Nissan e-Power engine works. The latest Mazda model equipped with the Wankel rotary is well known: it is the famous RX8, which went out of production in 2012.
