Mazda Begins Production of 'RENESIS,' the New-Generation Rotary Engine
Submitted by SuperUser on Tuesday, January 28, 2003 - 7:36pm

Mazda Motor Corporation today commenced production of its newly developed RENESIS* rotary engine at its Ujina plant. The RENESIS is a new-generation rotary engine employing twin rotors, each with a displacement of 654cc. The engine was designed especially to power the all-new four-door, four-seater Mazda RX-8 sports car, due to hit showrooms this April (in Japan, May or later depending on distance from Japan).

A ceremony was held at the plant in Hiroshima from 8:00am this morning to mark the start of RENESIS production. Six company directors, including Executive Vice president Hisakazu Imaki and Executive Officer Masaharu Yamaki, along with MWU's representatives and approximately 150 employees attended the event.

Executive Vice President Imaki said, "This RENESIS is a rotary engine developed especially for the all-new RX-8 and is a symbol of Mazda's revival. Mazda is currently the only automaker in the world developing and producing rotary engines. I'm extremely proud that the dedication, skills and enthusiasm of our engineers have enabled Mazda to provide the world with new-generation rotary engine. We will continue to pursue process innovations and the development of new technologies in order to produce high quality vehicles that fulfil the expectations of our customers."

Through the introduction of innovative technologies for the rotary engine -- such as the use of side exhaust ports and the new Sequential Dynamic Air Intake System - the 'RENESIS delivers a high power output for a naturally aspirated engine. In addition, the engine demonstrates significantly improved fuel economy and reduced emissions when compared with previous rotaries. By capitalizing on the intrinsic benefits of the rotary engine - namely, compact size, light weight and high performance - Mazda has created a totally new sports car concept - the four-door, four seater RX-8.

High precision quality that helps maximize RENESIS performance has been engineered into the Ujina plant. This precision is achieved through a combination of Mazda's extensive rotary experience and capability, and innovative development methods that are made possible through advanced digital technologies such as virtual simulations based on the Mazda Digital Innovation (MDI) project.

That is the number one asked question, the answer is: No, not yet, since most of the engines will be used for the RX-8.

In a few years when production of the engine well exceeds demand for the production line, and WE HAVE A LETTER WRITE IN CAMPAIGN, they may do it.

Everyone keeps asking is Mazda is going to turbo charge this engine. Turbo's generaly give high rpm HP (thats not the problem with this engine). The question should be when will we see a supercharger. That's going to give the engine the low rpm grunt/torque it needs. Look at all that space in front of the engine.

Have they indicated what to expect for fuel efficiency (MPG?) Any idea if the stock version uses the same 2$/gal 92 octane fuel my 3rd gen requires?

Count on me for the letter to make renesis engine production enough for rotary fans to buy Renesis engines. If we want the rotary engine to grow as a alternative to piston engines with full force, Mazda must make the Renesis engines available, and not expensive. A lot fo people w/no experience w/ rotaries tell me straight forward when talking about rotaries that rotaries are not reliable. I inquire, Have you ever had a Rotary engine? the ussual answer is no!, or else, they had one, but Harry the town mechanic specialized in Ford Comets was the "family mechanic" who advised them to get rid of it. Ignorance, but , let us reverse that trend, only like that, Rotary engines will be appreciated and better, improved through more testing and competition.

Biggest difference besides the body kit for the Mazdaspeed RX-8 will be the SuperCharger. (that's the current plan, at least)

Now, about conversion, I doubt it, from the factory at least. Good news is aftermarket places like RacinBeat or RE Amemyia (or whatever) will be selling the stuff to make it even faster. But, if you want to do a stock MazdaSpeed conversion of an RX-8, I suppose that through Mazda parts or MazdaComp, it could be done.

I owned Mazda Wankel Rotary Engine automobiles iRX3 n 1974 and RX7 in 1980. I found rotary engines extremely quick and fun to drive but apex seals had metalurgical limiations which caused them to wear rather quickly and from the first mile I drove it was necessary to add a quart of oil every 750 miles. This was dissappointing. Does anyone know if that defficiency has been ironed out in new version rotary engines? What is estimated MPG for 6-speed vehicle? At 55MPH what is expected engine RPM? What differences in engine displacement were considered in development for this vehicle? What is overall vehicle weight? Is this a front wheel drive machine? Can one use E85 fuel with this vehicle?
