    Default Report: Mazda rotary reportedly at least a year behind schedule, but work continues

    Filed under: Technology, Mazda

    Renesis rotary engine in 2009 Mazda RX-8 - Click above for high-res image gallery

    "We will never give up," says Mitsuo Hitomi, general manager of Mazda's powertrain division, referring to the automaker's long-running investment into the rotary engine. This vote of confidence in Felix Wankel's replacement for displacement will surely come as welcome news to rotor-heads the world over, but that doesn't mean there aren't problems in World of Wankel.

    Apparently, the so-called 16X engine, which is the latest take on the pony-keg-sized engine that spins into the stratosphere, is failing to meet emissions requirements set by the engineering team at Mazda, despite the fact that it is 30 percent more fuel efficient than the previous Renesis rotary. Impressively, Hitomi stated that the 1.6-liter 16X is slightly more fuel efficient than the automaker's standard 2.0-liter gas engine.

    It would seem that the rotary's well-known thirst for fuel has at least partly been quenched, but until the 16X is tuned to hit its emissions targets we can expect it to stay in the engineering department and off the showroom floor. So, when might we see a new rotary-powered machine from Mazda? "Maybe within two years we can tell you when we will introduce it to the market," responds Hitomi.

    Now, let the debate continue as to what kind of body and platform that engine will be featured in...

    if that happens, we'll never hear the end of it from those dorito boys...

    pretty sure a 1.6 SHOULD use less fuel than a 2.0

    I just hope they can engineer these engines fast enough to at least catchup and keep pace with the every tightening euro emissions standards...

    It better have a turbo or something because those gutless lawnmover motors they are putting in RX8's now are useless...

    Greddy is your friend

    As long as Rotary's still exist. Turbo's will be made for them.

    Not sure why you think 170kw from a N/A engine is gutless/useless??

    What would the MPS3 be without the aid a turbo? The normal Mazda3 2.3L in N/A form were/are 115kw so I would've thought 170kw in a N/A form was amazing.

    the Rx8 is about a one of a kind driving experience more so than it is outright power and speed. As much as I would like to see more powerful variants of the Mx5 and Rx8, I respect Mazda for keeping them as they are because its been highly successful for them.

    The efficiency figures Mazda are aiming for seem almost impossible for my mind. Even still, 30% improvement over their old rotary is quite a miraculous achievement.
