http://www.motoring.com.au/news/mazd...o-rotary-44652
Been a while since we had rumors of the next spinning triangle power plant but motoring.com.au is reporting possible twin scroll turbo rotary putting out 335kw (455hp) : "Rotary diehards would, of course, remember that Mazda's first-ever rotary-powered production car, the Cosmo Sport, was launched in 1967, making 2017 the 50th anniversary of that event. Earlier this year, the prototype for this new RX-7 was said to employ a naturally-aspirated rotary engine based on the 16X configuration. Using "laser ignition" that test mule was said to produce around 225kW. In less than six months, Mazda has decided to add a twin-scroll turbo setup, expanding power to some 335kW. We'd also heard that, in the absence of a suitable rear-wheel drive platform, Mazda was using a reinforced version of the next MX-5's platform which could accommodate the suggested 225kW. But now, with over 335kW on the table, Mazda has ditched the MX-5 underpinnings and reverted to a significantly rebuilt RX-8 platform for its test mule. Given that Mazda plans to celebrate the rotary-powered Cosmo Sport's birthday of May 1967 with the launch of a new RX-7, it stands to reason that we will see the all-new model in May 2017. "

A shortened, more powerful RX8 sounds amazing. It also sounds like the new MX-5 platform won't be as rigid as it should be if they dropped it...

Modern diesel isn't clean burning, they just have complex emissions control systems. One of the past problems with rotaries is that it is difficult to combust all of the fuel in the chamber meaning unburnt fuel in the exhaust (which is why you can find videos of rotaries shooting flames out the exhaust without even trying) which would put a huge tax on any emissions control system, let alone unburnt diesel fuel. This is all contingent on you getting enough compression out of a rotary to make diesel cycle work which has been tough from my limited amount of reading. |

I'm excited to see what Mazda do. It sounds like the are ready to make up for all the downfalls of the RX-8.

I think there is room for new engine designs, but the Wankel rotary is near its limit. It simply has too poor of a surface area to volume ratio. |

Mazda says "No" to future RX.
Rumors had been swirling about an RX car to be shown in 2017 and put into production by 2020. Straight from the mouth of Mazda's CEO:
http://www.msn.com/en-us/autos/autos...els/ar-AA7uOdn The Skyactiv MX-5 will remain the company's only sports car.

F@ck you MAZDA!!!! I wanted to give you my money but I hate you so much right now.
You better at least give me a MX-5 coupe with the mazdaspeed3 engine to fill that niche. And NO, an AWD Mazda 6 coupe is not a suitable alternative....
