Mazda Kabura Concept – Click above for high-res image gallery

According to a report from Autocar, Mazda is currently working on a successor to the old RX-7 and the current RX-8. (We've heard this before. Many times.) Believed to carry the RX-9 nameplate, the next-gen sports car is tipped to ditch the innovative but clumsy quasi-four-door layout of the current RX-8, and that the platform is to be spun off from the MX-5 roadster. But what you really want to know about is the engine.

Dubbed the 16X project, the new Renesis rotary engine is expected to grow in size considerably over the RX-8's and pack around 300 horsepower – quite a bit more than the 232 hp we enjoy in the current car. Mazda is also said to be hard at work keeping the engine as clean and efficient as possible, as the current RX-8's high fuel and oil consumption have driven it out of certain markets already. The Japanese automaker could alternatively turn the RX-9 project strictly into a hydrogen halo vehicle, which might be nice if you happen to live near a hydrogen pipeline, less so for the rest of us.

      I would not have bought my RX-8 if not for the rear doors and real-person-sized rear seat accomodations. Yes, I hated having to stop and check the oil half way through a road trip, and not being able to just back it out of the garage (without following the very specific instructions to not shut it off if the engine was not warmed up).

      Why does Mazda insist on that front end for the RX's? Just make a freakin' new version of the last RX7. Same thing with Honda and Toyota. Why's that so hard to grasp?

      They need to make it more fuel efficient, more reliable, and more torque. Then it would be something to compare to.

      Monte is the same ignorant people we deal with on a daily. Like piston engines don't have there faults. Show me a perfect piston engine Monte? ..... Thats right because there are no perfect piston engines. You know nothing about rotaries, you never dealt with rotaries, yet you spit the most obnoxious garbage out your mouth about them.

      The Rx-8 is my first rotary, I had V8's,V6's, I6's,V4's and I will say that the rotary is in no way shape or form inferior than its piston counterpart. 146k miles on my car, no blown Apex seals, rev the motor to the high heavens on the daily, put 1 quart of oil every 2500 miles(5000k is the oil change), track my car 4 times a year. Absolutely love it!
      Most of the problems come from people who know nothing about rotaries,operation or how to drive a rotary properly. People like yourself do the car no justice at all.

      Enthusiast get the RX-8 , all others don't.

      It warms my heart to see Mazda still playing with rotary engines. Can't wait for the results of their tinkering.

      until real photos of test cars emerges, we're basically reading the same info over and over again.

      stop teasing us with these 'news leaks' mazda and give us something concrete! like an actual production 16X engine that's ready to be put into real cars!

      If Mazda really wants to get people excited, they should take the RX-7, update the interior and body style a little bit, and then re-release it. I still LOVE those cars. I couldn't afford to buy an RX-7 back in the day, but have the means now. I would never even consider buying an RX-8 or the thing pictured above.

      ohh boy... all aboard the wankel train, horray for driving up maintenance costs for inferior technology. Just give us a nice looking standard ICE engine for the MX-5 and save the technology show for later
        • 4 Years Ago
        Put cast iron pistons in your car then tell me how inferior a rotary design is when it competes with ICEs with aluminum pistons.

      the platform is to be spun off from the MX-5 roadster.

      Which is spun off the RX-8....

        Post of a lifetime for the Simpsons reference that worked so beautifully.

        Mazda must move forward, not backward, upward not forward, and always twirling, twirling, twirling towards the future.

      *sigh* I just want a proper successor of the FD3S. Please Mazda, you do a great job with the Miata. It doesn't even have to be a Mustang/Genesis/Z killer; just something that can put out 300hp, stay light on its toes, and look amazing.

      Still the same old Mazda faux-design tricks, but maybe toned back slightly... ie, take a fairly standard profile, and add curly-cues, never use a straight line when you can insert a curl or a scallop, exaggerate, exaggerate, exaggerate. Good designers have original ideas, and know when to stop. Mazda goes for effect with no substance.
