Well, there is no pushing the envelope on engineering going on with a non running concept car. So what envelope is Mazda pushing exactly with the RX Vision?
I also would not call a 3 rotor (Renesis hybrid?) race/show car that actually ran laps, typical either. But yeah, opinions vary I guess.

Lastly, I'm not saying the Vision is special either as it's just design language.

You keep thinking there was something special about the engine. That engine didn't have Renesis side plates. It had the thick 20b center housing. I don't think Mazda would re cast the center plate to add the side exhaust ports for a one off concept engine when we all know the new design going forward is the 16x design. That engine was built with basic 13b based parts (which is what a 20b is) and I believe Renesis rotors. So we basically have a PP 3rotor in a fancy looking skin that can't pass an emissions test. So yea, just because it runs doesn't make it special.

See but that's the issue, you don't know jack **** about what that engine was or wasn't, you are just assuming. But like I said, if you don't think the Furai was special then maybe a Prius would be a better fit for you. Or maybe a Chevy Volt or a Nissan Leaf, you would probably love those too.

oh FFS again. the answer to what the engine in the Furai was was discussed here on this forum and the answers are still here.
it was a 13g https://en.wikipedia.org/wiki/Mazda_...gine#13G.2F20B with Renesis rotors tuned to run on E100 from BP. The tuning was done by Jim Mederer at Racing Beat on their in house bench with a guy from Motec because they were supplying the engine management. Hell somewhere here is a pic of Jim and the Motec guy sitting at the bench with the Furai motor on the other side of the glass. I just saw it a couple days ago when i was looking for something after Jim died

The famed Renesis 20B in what was the most driven and probably the fastest concept car ever. But yeah there is nothing interesting about it,

Yeah, I think we have established that it is a R20B (Renesis 20B). Mazda made it so they can call it whatever they want. Either way it was bad *** and died doing what it should have been doing.

Hell that engine was actually less special than your typical 20b pp because ANY builder would tell you that running higher compression Renesis rotors in a PP makes less power than the 2nd gen 9.7 rotors. Fact!

Interesting about the Mustang . . . But I have thought for a long time the next Rotary could/should be a hybrid, mainly for the low end torque assist and to improve gas mileage.

I wouldn't necessarily mind a hybrid rotary, but my question then becomes...how much weight will those components add? Everyone already knows the mustang is an overweight pig so it won't matter with that car. But with any rotary car, Mazda has always put together a light weight, low center of gravity, great handling package. How much would that be compromised after adding the hybrid components?

Well your entitled to believe the non sense Mazda tried to shove down the media's throat calling that engine an R20b. Those journalist are clueless about the specifics of this engine design. To even be considered a Renesis (by Mazda standards) would mean the engine would have to have the "Multi-Side-Ports". The Renesis name itself means "Rotary Engine Genesis". This engine had only the lighter Renesis rotors in your typical PP configuration. The fact that Racing Beat built the engine and not Mazda of Japan should tell you something. So I guess Racing Beat can call it whatever they want right?

It's just naming, the name Renesis doesn't mean jack **** from a technical aspect. And from the article I read, Racing Beat only tuned the engine in the Furai.
But either way it doesn't matter, the Furai was bad *** and a one of a kind. The Vision is a one of kind piece of art that doesn't run and will never do hot laps going brappity brap like the Furai did.

A bit difficult to parse the google translate, but this is an interview with Fujiwara (product development):
Fujiwara: "More on the rotor engine technology, please wait, when we will be more detailed information available to everyone."
It's pretty clear they are still developing the engine for use in a sports car. He specifically states they will be two development directions: Range extender for an electric car and the RX-vision.
Thanks to Blue on the rx7 forum, doing good work finding this stuff! The RX-7 confirmed to be in the pipeline for 2017---RX-Vision Unveil!! - Page 140 - RX7Club.com

Idk why I even bother to read these posts anymore.
I wish there would be a real hard news only thread that would not allow speculation.
It's the same stuff over and over ad nauseum.

oh no, you are joking...whats wrong with these car companies, they obviously want to sell less cars at higher prices, a hybrid Mustang, they cant be serious!
Yeah, lets add more cost, more crap, more technical babel, for what, the EPA, for the loony left who has delivered me the most expensive ******* power in the world (in my state) because of GREEN ******* energy, we have in Australia 700 years of coal left, THE cheapest form of combustibles to generate power. But no we have to pay through the nose for ******* useless government subsidised green energy, roof top solar, wind farms shut down when it is too windy! which does not work in a storm, anyone read where South Australia (my state) was totally blacked out for over 24 hours, because of a storm and because we had no base-load, thanks to greenies, 2 million people all without power.
Hybrid, electric, I don't want any of this crap, IT IS NOT NECESSARY!
BTW: Here electric cars sales have tanked, they cant give them away....almost.

ASH you make valid points. but I am afraid it is too late. VW, Ford, Audi, Mercedes etc are spending billions to feed us these electric and hybrid cars, as their market research says governments, and buyers want this crap, and will pay for it to meet the future environmental restrictions . There is no turning back. Just hope that a few car makers will have the guts to give us a few real cars for the enthusiasts. Not holding out much hope.
