Don't get too excited unless you're interested in a hybrid. At least, Mazda is reviving the technology. I wonder if it will be a one or two rotor engine?

Oh, but think of the new Power Wheels builds we're gonna start seeing!

It's a small one rotor. I think it's even smaller displacement than a current rotor.
It will only fire up when you are running out of battery and you need these extra kms.
It will be almost silent and give out very low emitions. It won't even have a power train. It will just produce electricity to charge the battery and then the electric motor

Look at this way. Mazda isn't abandoning the rotary and may continue to at least somewhat support Rx-7 parts for a while longer.

Makes you wonder , why generator manufactures never used a rotary for power source....

IDK, but you raise a good point.

I do know that there is a UK company (https://www.aieuk.com) that makes small diesel rotaries for unmanned aircraft system (UAS) sometimes called a drone.

1. Smart business choice - Why invest in the necessary non-recurring engineering expenses & new production cost unknowns associated with adopting rotary power when proven piston engine tech (gas or diesel) will do the job for the customer? Size/weight/power advantages of the rotary (if any) are minimal for most portable generator applications.

2. Not sure if this holds true anymore, but there may still be licensing fees to paid for adopting the rotary. Back in the day, Mazda, GM, and anyone else attempting to get in on the rotary game had to pay NSU for the intellectual property rights to us Wankel's invention.
