Since the RX-8 was discontinued in 2012, there have been rumors that Mazda will revive the rotor engine. Indeed, in the upcoming plug-in hybrid version of the MX-30, we were pleasantly surprised to find that it is equipped with a rotor engine as a range extender for the battery. However, it is clear that Mazda is not willing to let the once unique learning act as a miscellaneous auxiliary, in the recent European Patent Office website, someone found that Mazda has filed a patent application for a three-rotor hybrid system!
Judging from the exposed patent diagram, the new powertrain will adopt a front-facing rear-drive layout, which is also in line with the settings of the new rear-drive platform previously announced by Mazda. Specifically, the numbers 11, 12 and 13 in the figure are three-rotor engines, and 14 are 48V motors, and the number 10 of these four parts constitutes the 48V light mixing system of the whole vehicle. Its overall structure is similar to the three-rotor engine in eunos Cosmo, which was introduced in the Japanese market in the early 1990s.
In addition, due to the particularity of the rotor engine, the whole power system is very small, almost flush with the horizontal height of the wheel center from the position layout, and the lower center of gravity can bring better vehicle handling, and can also bring more exaggerated body shape design, so many netizens speculate that this is also a patent diagram of the Mazda RX-Vision coupe.
