Intriguingly, the 2-stroke 16X rotary prototype does not seem to mind what fuel it sips,
I found that to be pretty funny. :chuckles:

Diesel here is 50 cts cheaper than gas, I can see rotary owners here liking the idea.

There is no way it can run on Diesel and gasoline. Mercedes had a design and patent for a Rotary Diesel, they utilized a 2 rotor configuration but it was very different to a conventional Wankel. They used the front rotor to pre-compress the fuel/air mixture and then sent it to the 2nd chamber where it would be ignited. Diesels need such high compression and fuel pressure to operate, it would be nearly impossible to convert it to gasoline on the fly.

There actually is, the words are Curtiss-Wright. They developped the technology for the military in the 70's and it was an engine that ran on diesel with spark. That would cover Marc's comment at the same time. ;)

Ok and how would they solve the pre-compression rotor -> combustion rotor housing. There is no way for a rotary to build the compression in a single housing.

todays humves, probably a product of the 70s, can run on diesel, gas, just about anything

now saying that they will run like sh!t on gas but they will run and get you where you need to go

Correct, but then their engine wasn't a true diesel that used compression ignition. It ran relatively low compression and made use of spark ignition to ignite the diesel fuel by stratifying it through direct injection. It wasn't a true diesel in that sense, but it ran on diesel fuel nonetheless and from what I understood ran quite well. There are some SAE papers around that cover it.

The reverse compatibility of those components are the main issue.

Regardless, we can all agree that the latest news is a BS report.

Next-generation Mazda RX Car To Be a Rotary Hybrid
The surprise here is that the new rotary will have company in the engine bay via forced induction or some other kind of assist. There are murmurs that the company is working on a hybrid version using the rotary engine. Details are still sketchy at best, but the good news is that we’re relatively sure that the rotary engine and the RX name is here to stay.

Mazda plans new turbo RX-7
Mazda is planning a turbocharged successor to the much-missed RX-7 that could arrive as soon as 2013.

The new RX-7 — which could be called RX-9, according to insiders — will retain the rotary Renesis technology employed by its predecessors and the RX-8.

This is despite the RX-8 — production of which will end next month — suffering from a shortage of torque and poor fuel economy.

But Mazda is considering a wide range of radical options to help the powerplant deliver better economy and the torque required to keep pace with rivals like the VW Scirocco.

One source told us: “We’re testing the rotary in conjunction with technologies including an electric turbocharger.”

The new model is seen as ideal candidate for the Nagare design language, which is inspired by nature — in particular, wind and flowing water — and produced five highly rated concepts in 2006 and 2007.

Nagare will not feature on any future Mazda concept cars (the firm will reveal a new design direction in the autumn) but it will still make it on to the firm’s upcoming production cars, including the newly launched 5.

Employing Nagare’s side panel creases should prove a more straightforward process on the RX-9 sports car.

now I know that report is bunk because Mazda officially denounced Nagare design language on their new models.

So this "source" is talking out their ass.

Hell, I'd like to see a twincharged (turbocharged / supercharged) gas-electric hybrid rotary

That'd be sweet.

I thought this too, but then again it could be kept slightly the same since it is a car with a legacy to uphold.

RX-7 to RX-9? Mazda Still Toying with Name Change, Rotary
Mazda still is teasing us with rumors of the return of the RX-7; rumors that continue to heat up as production of the RX-8 - the Japanese automaker's only Renesis rotary-powered vehicle in its fleet - winds down this year.

We hear that the engine still being considered for the new RX-7 is a version of the 16X direct-injection rotary powerplant first unveiled at the 2007 Tokyo motor show. But according to a source close to Mazda, the engine still does not meet the company's goal of lower emissions, better fuel economy, and beefier mid-range torque, issues that plagued the RX-8.

One insider tells us that to remedy this situation, engineers are thinking outside the box and "testing the rotary in conjunction with technologies including an electric turbo." We were also told not to expect a hybrid or hydrogen interference, as those have been tested and apparently don't solve the underlying issues Mazda is trying to address.

In addition, we hear that if the car gets the green light, Mazda is seriously considering changing the name from RX-7 to RX-9, a moniker that has been tossed around before. If the RX-7 actually does reach production, don't expect it before calendar year 2013 at the earliest, possibly wearing some of the same design cues featured on the latest Mazda5 as rendered in the illustration at top. Mazda has indicated that its design direction will be moving away from the 'Nagare' flowing theme seen in the illustration, but it will likely take a generation or two for the new direction to supplant the present aesthetic.
