Mazda rotary engine development to continue

 Mazda rotary engine development to continue
Mazda RX-8 Spirit R special edition JDM 07.10.2011

New model could be out within five years

Mazda confirms they haven't dropped plans of developing a new generation of their rotary engine.

The Japanese firm stopped making its Renesis rotary engine in June 2012, but the good news is development will continue. One of the company's engineers told Autocar he hopes rotary engine production will restart within the next five years, but for the moment nothing is certain.

If green-lighted, the new generation of Mazda's rotary engine will be available at first in a naturally-aspirated variant which will be followed by its turbocharged counterpart if testing goes according to plan.

When the Renesis rotary engine was discontinued last year, the firm's PR department said they are "zealously working on new models to house the next-generation rotary engine". Hopefully, they'll live up to their promise.

Never understand the aim of this engine but i like to hear that the legacy of the legendary RX7 is to live.

The rotary engine is a big shrug. If you want to make a sports car with an exotic engine what about 2-stroke: very similar concept as you get a great sound, high revs, and low engine weight. A lot of the infamous characteristics have already been ironed out in the outboard/powersports world.

Rotary range extenders? It makes sense to have a small powerful engine as the range-extender and it wouldn't stress the engine as much- Rotaries aren't the most durable are they?

What a wonderful car the RX-8 is/was...STILL one of the best balanced RWD 'only' Sports Cars EVER made....it sticks to the road like glue, the simplest, but best multi-link rear suspension ever made...Everything about the last series 2 RX-8's was well sorted and perfect...a joy to drive. I hope Mazda makes another RX-, but ONLY as a primary power, anything else will never be a real RX-.

I am surprised germans aren't putting their hands on it. Rotary engines are way more efficient since there is no death points to overcome but valves and other parts are more complicated to run. Fuel efficiency needs to improve.

Too difficult to meet emissions regulations because of (among other things), the oil being consumed during combustion. Not to mention the inherent lack of tq in the design. Most cars are simply too heavy nowadays.

exactly... the real problem is the oil consumption during the combustion - which cannot be good no matter what ... This simple fact leads to high polution figures ... On the other hand - who knows, maybe these japanese guys figured out one functional solution ... who knows ...

The "Oil Consumption" in Rotaries is NOT a Fault, but NORMAL Engine Operation ...The Series 2 RENESIS used from 2009-2012 actually uses less normal engine oil use than any other Rotary before it, in other words the Electronic MOP's (two) are far more precise and accurate, measuring and using only what is needed to lucubrate compression seals (Apex and Side Seal). There is NO other way, other than using some type of Oil... Emissions is actually not an issue with Mazda's new patent nano particle CATS anymore...THE issue is MPG (gas/petrol) consumption.

Hope they add direct injection & multispark coils for the rotary engine!
