Mazda Promises RX-7 Successor... Again.

[@Nafeels]

You didn’t mention one of the best part of the patent release: Rotary with a VTEC! That’s right! Mazda figured out a way to completely control the intake and exhaust “lift” and timing with…. Get this… a HUGE ASS electric motor. Since the rotors and e-shaft assembly are light enough to be hooked directly to an electric motor, Mazda engineers can change its rotation speed directly. Add that to extra auxiliary electric motors and the patented rotary engine will have a greatly peaky torque curve and an incredible throttle response thanks to NA engine. Same reason why Bugatti said “fuck y’all” and made an NA V16 for their upcoming hypercar. With direct injection and EGR, complexity finally arrived at Mazda’s thoughts. Rotary is back on the menu, boys!

[@rahulmenon6073]

Sorry friend, you're not making sense. Could you please elaborate how an engine with no valves (but ports) can mimic a Vtec, with electric motors ? I'm puzzled....

[@Appletank8]

​@@rahulmenon6073 I believe Engineering Explained did a video, but the tldr is instead of variable valve timing, they're doing variable stroke timing. Instead of extending the time a valve is open, they instead extend the time the rotor is doing a stroke by slowing it down at that moment, then speeding it up afterwards.

[@XxXnonameAsDXxX]

I dont see how they could solve the emissions issues with these. Im all for the rotary coming back better than ever but all of these point to a super optimized generator for hybrids. I would love to buy a performance hybrid with this setup tho.

[@Appletank8]

@@XxXnonameAsDXxX Even according to Mazda's own released numbers, it gets around 31 mpg, which is barely any better than a non-hybrid from several years ago. Against its contemporaries like the Rav4 hybrid, which gets low 40s, it really sucks. I remember a paper from around a decade ago, and even assuming a spherical rotary with perfect reliability, its best thermal efficiency is still about 20% worse than a piston's.

[@Nafeels]

⁠​⁠​⁠@@rahulmenon6073Variable stroke as Appletank said. A large electric motor not only adjusts the timing between the different strokes, but also putting extra torque at the output shaft. The combustion event in a rotary engine also briefly halts and reverses the direction of the rotors before turning in one direction. Considering an infinitely variable rotational speed, the electric motor can either eliminate this “hiccup” completely at high RPM for more power, or prolong this “hiccup” and increasing MPG/reducing emissions. However, I’m definitely talking out of my ass here. Until Mazda releases their test bench research, we won’t see these types of technology carried over until a few years later, if any.

NGL, this new guy giving off 'car daddy' vibes that makes me want to listen to him all day. LOVE IT!!!

[@nkermit1]

Talk cars at me, Zaddy T!

[@alexmason7103]

This guy has completely ignored the shocking fuel efficiency of rotary engines, I don’t have any numbers to hand but per unit volume of fuel, what’s the difference between piston and rotary engines in terms of energy per unit volume? Engine size is of no concern in modern day cars - surely it’s all about how much electrical energy you can generate per unit volume of fuel?

[@Appletank8]

Yes that's the real limiting flaw of the rotary. Even assuming perfect reliability, the geometry alone causes it to be 10-20% worse in combustion efficiency than a piston engine. Stretched combustion chamber wastes energy into heating the housing, a moving combustion chamber forces the flame front to chase the rotor, and the holes required for spark plugs is an inherent leakage source. You might be able extract an extra % or so from slowing the power stroke, but it's a difficult problem.

[@Budgy.Derpy12]

I'd settle for a body kit/conversion for a MX5. Just for a great handling car, and something that resembles the RX-VISION concept many, myself included, fell in love with.

[@dolan-duk]

RIP OVERDRIVE. It's now another of those talking head channels and no longer filled with fun videos.

[@AbandonedRaven]

I truly don’t care if it’s rotary or has some sort of hybrid, as long as it looks somewhat close to how the concept car looks, I’m happy. Especially if it’s around the 30-45k price range. I love my Mazda now, so I’m really hyped for whatever the new RX will be like.

[@Dyltheboy]

So you expect it to be the price of a current Miata? Delusion bro

[@AbandonedRaven]

@@Dyltheboy Regardless, I want one. My main concern isn’t so much the price, nor did I intend for that to be the point of my comment. More so the looks and how it drives/sounds. I’m not a big Supra guy but I loved how the FT1 concept looked, and the actual car (before heavy body modifications) looks kinda eh to me. The only thing that might kill this particular car for me is if it was front wheel drive, but based on the patents mentioned in this video it’ll be RWD hopefully.

[@Dyltheboy]

@@AbandonedRaven Mazda knows what they’re doing. They would NOT make the mistake of making it FWD. Maybe AWD with rear bias but I don’t see Mazda making that mistake

[@Litevaar]

For me, if there isn't a rotary engine powering the wheels, it's hard to get excited about it at all.

[@AbandonedRaven]

@@Litevaar if they suddenly cancelled this whole rotary thing and just threw in a modified version of V6 twin turbo from their other vehicles I’d still like it. I just want a good looking new sports car that sounds good. Something about the front and overall styling of this really works for me (along with their recents designs in general). But this particular car I think it’s because it reminds me of the Ford GT90 concept car from the 90s. And other recent “cheaper” sports cars just don’t look that good to me. But I care a lot about design sometimes more than performance due to my particular interests, and I know that doesn’t apply to everyone; especially with a lot of car guys. Edit: I remember a video where someone had an FC RX7 and he swapped out the rotary for a 1JZ; and it still sounded and look like a clean street car. Just so you get an idea.

[@Kacpa2]

Stop with the damn hybrids and the damn rotary. We need NEITHER. Just stretch MX-5 a little and make MX-8 ie. RX-8 but with convetional engine. A fun and practical 2+2 coupe(and ideally also with a 2nd shooting brake/2door coupe-wagon so its properly practical cargo wise too) to rival GR86. Sadly mazda stupidly refuses to do just that... Honda shouldve done similarily basing of S2000 a decade ago... We need such cars. And 2 japanese brands making the best engines for such refuse too

[@johngalt97]

Using a generator/traction motor is also a continuous transmission. Mazda figured out how to use the generator part to enhance efficiency, too. I’d like to see a passive sonic supercharging exhaust, eventually.

[@noncog1]

The rotary should only operate at one speed, it's most efficient, so there isn't need for variance on the load side. As far as the other bit, doesn't apply to rotaries since they're 4 stroke

[@Litevaar]

RX8 doesn't have as much HP as the RX7 but it revs to 9500RPM and has a higher compression ratio, it's the most powerful NA rotary engine ever made for production cars. 240HP from a 1.3L engine is impressive without a turbo. It's Ford that forced them to take away the turbo and also insisted that the car be a "four door sedan" lol.

[@converge8008]

Yeah everyone forgets that renesis is NA, like yeah it's only 240 at the crack, but it revs to the moon has a perfectly linear power band and makes such a nice sound with an exhaust. BRRRRRRRRRRRRRRRAAAAAAAAAAAAAA

IMO Mazda made a mistake in not trying to capitalize on a rotary generator's greatest strength, its small size, by not at least having extra EV range compared to its rivals. Because the fuel efficiency still sucks as a generator, around 31 mpg according to their own numbers, you really want to avoid using it when possible.

Using the rotary engines as a range extender în an electric car , or making a hybride with a rotary îs just an overcomplicated and again an inconvenient solution. Comon guys, We just want a classic, affordable(Max. $60K) , RX 7 with a V6 turbocharged 3,0 liter în the 400 hp range to compete with Supra and Nissan Z.

Dude, you talk about a hybrid car, which means people are looking for efficiency, but then never talk about how inefficient rotary engines are. You compare it to a GM engine and say... hey look how little power this engine makes. So dumb. It makes that much power because that's how much they wanted it to make. Why don't you look at the 1.5L turbo GM made that was rated at 284HP? Because it doesn't fit your narrative.

[@davehoffman515]

Porsche makes dual drive hybrids with 400+hp with an estimated 80 mpge thanks to the electric doing a lot of the heavy lifting in day to day driving so, if a dual rotor hybrid can get near that for under 50k it's going to do quite well. The Renesis peaked at 232hp naturally aspirated at 1.3L. Not many engines out there pack that much horsepower into that small of a package. What does that 1.5L GM do without turbo? I'm not sure what your point is. Throw a turbo on a Renesis and people are making 400+. 3 rotors clear 1000hp. The new rotary design has an advanced VVT like design to burn more of the fuel than previous rotaries to increase fuel efficiency. I doubt it will be sipping fuel like a Prius but, should be better than the 16-ish combined mpg I get in my RX8 and get more hp per rotor due to a change in the rotor shape.

[@Appletank8]

According to Mazda's release data, it has 400 mile total on average. its EV range is 50, its tank is 11 gallons. 350mi/11gal is roughly 31 mpg. This sucks. In comparison, the Rav4 Prime gets 40 at minimum, and an equivalent electric range.
