Spiritual successor to the RX-7

New details are starting to emerge about the 2012 Mazda RX-9.

According to AutoCar, the RX-9 will be the spiritual successor to the RX-7 and feature a traditional two-door body. It is rumored to weigh approximately 1250kg (2755 lbs) and share chassis components with the next-generation MX-5.

Power will be provided by a new rotary engine, which is expected to use an electric supercharger, with upwards of 300 hp (224 kW / 304 PS). Despite the added performance, the RX-9 will be more efficient than the RX-8.

A launch is scheduled for next year.

Mazda are on a roll these days. This RX-7 Concept successor could be potentially big for Mazda! Watch this space.

Article and some comments fail, Nagare design is out, Kodo is in, any future rx-platform will have similar design structure of Shinari. Sky-G 1.6 liter Rotary engine still needs some improvement in co2 and emissions department before tinkering with power adders. Where this launch rumor came from i have no idea, Ikudo Maeda (rx7/rx9 designer)said it himself earlier this year Mazda Corp has no plans right now on producing a rx even if they have concepts already renderd.

2012 can't get here soon enough! rotary turbo engines rule.

With piston engines getting so much power and fuel economy from a small displacement these days it becomes harder and harder to justify gas and oil-thirsty Wankel engines I think.

Mazda is done with the Nagare design style. I'm tired of hearing about Mazda MIGHT do. Show me a RX-9 then I'll believe it! What will they do with the RX-8, does anyone have an idea?

bump. I know it's a bad economy but sooner or later Mazda needs to make up it's mind if they want people to take them seriously again. Just give us the furai and the next rx7 and all shall be forgiven!

2700lbs - Nice! Two-door - Nice! Rotary (which is efficient) - Nice! Supercharged - Nice! This thing is going to be somethin' to watch out for...

Not convinced about the electric supercharger, when batteries are empty (likely after few seconds) you end up with 200hp and very few torques... I'd support Dolomight's comment, adding serial sequential turbochargers as used in modern twin-turbo diesel cars (launched by the BMW 535d).

If the alternator is powerful enough, then you won't have to worry about batteries draining. I do remember a story about Mazda experimenting with "hybrid electric turbochargers"... that is to say that the turbine and compressor are not physically linked. Instead there is a generator on the turbine, and a high speed motor on the compressor. The advantage being that the ecu can spool up the compressor as soon as you hit the accelerator. Sounds interesting. Maybe that's what they're talking about here.

BMW's 35d concept won't work on rotaries. As a matter of fact turbo-charging won't work on rotary engines anymore period. Inherently, the exhaust gases of a turbo-charged rotary engine are cold (not hot as they should be) - this prevents the catalytic converter in the exhaust to do its job and reduce some of the harmful substances. It is for this reason that the rx-8 wasn't turbo charged either, the emissions would've been too high. Sure, the rx-7 enjoyed a turbo rotary engine but back then emission restrictions were virtually nonexistent. Personally, i'd prefer a larger displacement (say 2l instead of te rx-8's 1.3) naturally aspirated rotary with the ability to rev to 12000 - 13000 r/min. Now that would sound amazing.

^^^Silent bob^^^ Actually, you are quite wrong about that. Rotaries, turbo or not, have considerably hotter exhaust temperatures than your typical piston engine. It will easily make your headers glow red, and the typical steel tubing and even mufflers wont last long in the temperatures a rotary exhaust will push through it. As for the RX-8, that it not why it wasn't turbocharged. The RX-8 was never meant to be as hardcore, or outperform the RX-7. It was meant to be simpler and cheaper, not meant to beat the FD3S.

I don't like Mazda's Nagare design style, but new RX9 seems to be interesting

As long as they make it as nice looking as the FD3S and drop a 3-rotor in it, I'm onboard!
