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...

What about a diesel rotory? Good emissions, and now they have to fix the apexi problem

One of the things holding the rotary back is the weight of the rotors, diesel would mean higher compression which means higher stress which means a beefed up engine which means heavier rotors and rotating mass, which means it would not rev as high as past gasoline examples. It may get enough torque to compensate for the lower redline but it's still a sacrifice worth noting.

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.

Yeah...I mean who the F would want to put a hybrid system on a sports car! That's for hippies!

Ok...Maybe he was just referring to all electric cars. Those are probably super lame to drive and not very fun.

Ok, off my soap box.

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.

It doesn't. You can get 10:1 practically, a bit over 11 with a completely flat rotor, which would cause all the charge to be concentrated around the apex seals which would be bad.

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.

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:

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....

Sad, sad day...

emissions= no rotary engine

Why is the NSX a cock tease? Isn't that still being released next year?

Yeah I'm pretty sure people have been saying that 'it's coming out next year!' since before it was discontinued, and just like people around here there were 'rumors' of a second generation with 'moh powah' since before there was a forum dedicated to the NSX.
