Mazda did say one time that they would never give up on the Rotary as long as the company existed even if there was no publicly available version of it, that they would always keep working on it internally. I'd love to see them go for a public version again.

The car industry has had so many shocks that it's now on life support😂

I love how Scotty included Liquid Piston in this without actually saying anything about them. Their Peanut in a Triangle design solves a lot of the problems that the Wankles have. I am the former owner of a beautiful Gen 2.

I currently own a 93 twin turbo RX7 and a 88 turbo RX7 BOTH RUN ha!. IMO i feel Mazda REALLY puts in the time and R&D into making great cars I'm looking forward to seeing what they will do. The Rotary community is HUGE and with the growth of technology these engines just keep getting better and better!

Driving a manual RX7 is like driving a fast airplane. I love their power and high RPM.

I had and RX-3 and an RX-4 and loved driving these rotary engine cars. There’s no doubt the rotary has issues that need fixing, but the power, smoothness, quietness and lightness are great to live with.

Great vid! I've always thought the idea of a rotary engine was super cool. Ever since being a teenager I have been fascinated by this motor that is piston-less and non-traditional. I hope Mazda can make it happen. While the rotary engine may be "dirty" it has so much potential to create HP in such a small package. Thanks for the info!

I owned 2 RX-7s. I'll never again own a rotary engine. I had 4 episodes when I couldn't get the thing started and had to have it towed to the dealer to start it. Once it misses that initial start attempt, they are done. The 1 time I did get it to start was when I put it on a battery charger and got it to start after cranking it for 10 minutes on and off. That warmed up the engine.

Im grateful my uncle taught me how to work on these motors growing up. Family has had Rx7's left and right. It was fun working on these. You can take everything apart and rebuild in a day of you know what your doing.

Just for reference the 12 rotor was unveiled by Tyson in 2015 and given to Rob Dahm in 2023 the motor has been reconstructed with some much needed machining and is getting upgrades that may actually achieve the 5000 HP goal

I loved the Mazda rotary engine, I bought a new RX7 and it was a fun car to drive. I always noticed at higher speeds 80+ the engine sound was like a sewing machine it was so quiet. And no vibration at all. I really hope they bring back the rotary in a twin or triple rotor, that would be AWESOME !!

Loved my 1st and 2nd gen RX7s, never had an issue with oil burning. I drove mine in the city and had one that I sold with over 200k miles and still ran great.

In years past Mazda has said that one of the biggest problems was to get the apex seals to work over a wide rpm range. Making the engine into a range extender makes perfect sense as you can optimize the seals to work at the recharge speed. The rotary engine has always been simpler and smaller than the Otto cycle.

Quick point of correction as per knowledge gleaned from Rob Dahm's video "Fixing the BIGGEST Problems of the Rotary Engine" : one of the issues of rotary engines is that to boost adoption, they routed the oil pan's oil to a port to lubricate the apex seals, except synthetic oil doesn't burn cleanly. To remedy this, the port can be plugged at the expense of making a premix of gas and 2-stroke oil that's meant to burn much more cleanly. The oil pan's oil stays in the oil pan and is used to lubricate the rest of the engine with whatever oil you want.

I am interested in seeing rotary engine innovation especially with hybrid vehicles. Seems like a perfect matchup. Unlike the high power applications which do not highlight the rotary benefits. Absolutely love your presentation of this complex material! Thank You Scotty!

I've always loved my rotaries. And most people that have used them will tell you the same. There's just something about them. Thanks for this great video!

Would love to see the rotary make a comeback. Love the RX7.

The rotary engine is legendary.

Drove an RX4 for 150k miles, the last 75 k with a Racing beat intake with 550 cfm Holley. Wonderful ! Later, put a 13B in an Alfa Gulietta. Sold it for a big profit. I'm a believer, enthusiast, and promoter of rotarys.
