What do you guys think? To me this is as promising as it gets that Mazda is in fact releasing a new rotary sports car. |
Verrrrrrrrrrry Interesting News .Something is going on at Mazda

This is cool. I wonder how they will get around the side seals failing as is common with an turbocharged RX-8 engine.
Maybe because the side intake and side exhaust ports are on opposed sides of the engine which allows them to run a different seal configuration on each side of the rotor? Or maybe they will recirculate a lot of EGR during boost which lowers exhaust temperature. Anyway, very curious to see if this tech will actually make it into a product someday, and what the application will be. This seems too complicated for an engine that will just function as a range extender. |
Weren't they working on a hybrid that uses a tiny rotary as the gas engine? Could have sworn I read that somewhere...here!
Maybe these patents mean they're moving forward. https://www.drive.com.au/news/mazda-...iveline-120928 |
Mazda has confirmed they will release the all Mazda EV with the single rotor range extender as a 2020 model and then follow up with further hybrid models based off their collaboration with Toyota.
It has been variously reported to be a crossover and based on Mazda3, though the prototypes were based on the Mazda2. My bet is it will be an optional model of the freshly debuted CX30 platform. |

this all seems interesting, but i made the decision a while back not to believe anything rotary until i can go see it on a dealer floor.
that said, i wonder what chamber size/dimensions they went with for this one. |
So the most exciting thing about this patent is this diagram - as it clearly shows an FR layout car (as opposed to a range extender):

turbo looks like it is bolted to the engine similar to many these days...
|
definitely interesting.... i'm still not convinced on a rotary sports car just yet but promising.
