Happy 40th anniversary !

[NOPSTNS]

as of the may 2007, mazda has been producing rotary engines for 40 years!\

in 1967 the cosmo 110s was released in japan. it was a 1.0 liter rotary with 110hp. thats 110hp per liter in the 60s! in 40 years the engine has only grown 20 cubic inches and horsepower has doubled since then!!!!!!

1970 was the release of the r100 for the US, this yr marked the entry for wankels in america. then the rx2, onto higher numbered rxs, my personal fav the FD rx7. production rotaries hit a pinnacle in 2002 when mazda released the limited edition Spirit R. available in type A,B, and C this limited run model was to give the final production year of the rx7 to be a memorable one. the spirit R type is rated at 276hp but it was clear it was much higher than that.

rotary engines may have been cancelled for the US shores after 95, but mazda has continued on with production until 2002 and then in 2003 they released the RX8, there was no cease in production of rotary engines (contrary to popular belief).

extreme changes in rotary technology were realised with the release of the Rotary Engine Genesis (RENESIS) engine, a topic for another time!

mazda remains the ONLY japanese company to ever win at the LeMans 24 hr race. in 1991 they ran a 2.6l 4 rotor twin turbo producing about 700hp at 9,000 rpm. that all 3 entrants placed in the top ten and first place was us!

the 787b was the name of the car. and rotary engines were given a 15 yr ban in lemans until piston engines caught up in technology. in 2006 we returned with a 3 rotor N/A engine and were hit with more restrictions than ever (worst of all for the dear wankel was the throttle body inlet restriction) and after a lukewarm season mazda replaced the 3 rotor with the new 4 cylinder direct injected turbo they run in the speed6, speed3, and cx7. displacement is turned down to 2.0l by stroke reducing measures....

in 2010 mazda will be releasing a new rotary engine, porducing more power, consuyming less gas, and having better emissions all at the same time. there is much speculation as to what they have changed, my personal opinion points in the direction of....DIRECT INJECTION! also a topic for another time......2010 is going to be 40 years of rotaries in america so this will be a well planned event. no one knows what car will bear this new rotary, most believe it to be the second gen rx8 (i am one of them) some think a return of the rx7 is on its way, some think it will go into some other concept, who knows....only time will tell........



heres to another 40 of equal accomplishments.


(pics and a video demo of the rotary to be added shortly)

I don't think the new Rotary car will be called an RX7, but I think it will be something like a 2nd generetion 2 door RX8 or even and RX9 that is a 2 door. I believe the 787B was a non turbo. I wish they would release a turbo model.




From what I understand the RX in RX7 and RX8 means Rotary Experiment 7 or 8. So I don't think they would go back in numbers.

[FlashFive]

I think it will be either the next gen rx-8 or the kabura. The Kabura would be sick car to stick the rotary in to.

[NOPSTNS]

the 787b wasnt twin turbo'd? oopsy

RX stands for Rotary Sports

and i dont think theyll go backa number, itll def be the next gen rx8 gettin the new renesis.

kabura + slightly detuned renesis = RX-3? anyone?

heres some shots of the inside of rotaries, and a shot of the 12 sparkplug equipped 787b! note the intake runners....they are a variable length velocity stacks that change length depending on rpm!

[NOPSTNS]

here are some other shots.
pic three is the shot of the only moving parts in a rotary engine. just three moving parts......!


ten points to who spots the hydrogen renensis, and which one is the rx7 engine

[redline]

I always thought the RX stood for Rotary Experimental, cool info none the less! it amazes me how these engine function.

[Silverfc88]

I don't no man, I've never heard of it being called Rotary Sports. I've read Rotary Experiment, Rotary Expermimental and Rotary Export.



This makes sense though.

etc. etc.

X is just a popular moniker in sporty cars. Period. Mazda eXported the REPU, Cosmo, etc. without putting the X in the name. Mazda sold the RX-7 as an RX-7 domestically. X does not stand for eXport (nevermind that export starts with an 'E'). By the time the RX-7 came about the Wankel had been around for over a half century, Mazda had used rotaries in several models of cars, and there was hardly anything experimental about a tiny two seater, since the English and Italians had made millions of 'em prior to the RX-7s inception. RX-7 does not stand for Rotary eXperiment. It wasn't experimental, it was proven to work. No ammount of "I heard from my doctor's trainee nurse's former roomate's best friend that it really, really does stand for..." will change that.

The Japanese just like the look and sound of an X in the name of cool cars, just like they (and other car makers) make up words as brands and names. 'Acura' sounds like 'Accurate', so hey there's a good name. Allanté sounds kinda italian, so GM used that for a snooty overpriced drop-top. Same with Fiero for the working-class pseudo-Italian flavour to a 2 seater. The words didn't exist, didn't stand for anything, but just sounded neat.

Do Nissan owners debate if their 300 is a Zoological eXperiment? nope. Is an NSX officially 'known' as the Nice & Sexy eXport? Uh uh. If Mazda was that sticky on 'descriptive' names for their products they wouldn't even be labelled as Mazda products but Toyo Kogyo, and we'd be driving TKR-7s.

It does sound like something they would do. So in reality it means nothing. LoL..



I could've sworn the 787b was non turbo. Oh well.

[antman0408]

The 787b was a 4 rotor NA.
I tried to find out what RX stands for, most say rotary experimental, but I think no one really knows what it stands for.

[Cardriverx]

someone likes rotarys.. hey, have a spare 13b layin around that I can put in my miata? =). congrats mazda!

[NOPSTNS]

i HAD a 13b N/T from an FC but it was stolen from me at work...

2010 will be 40 yrs of rotaries in america and mazda is promising a new rotary engine for 2010 so thatd be good timing eh?


cross ur fingers all aluminum direct injection! 13B DISI anyone?
