Mazda reveals 25th anniversary edition MX-5 Miata alongside next-gen chassis

Ford may be celebrating the 50th anniversary of the Mustang this week, but it's not the only automaker with a sports car icon to fete at this year's New York Auto Show. Mazda is also celebrating the 25th anniversary of the MX-5 Miata with an array of 15 classic models. It's also showing off the chassis for the next MX-5, and unveiling a special 25th Anniversary Edition.
The special edition is based on the retractable hardtop model with either manual or automatic transmission, Bilstein shocks, a metallic red paint job with contrasting black roof and an off-white leather interior. Naturally, special badging can be found inside and out to set it apart from the record 940,000 other MX-5s sold to date, and just 100 examples will find their way to US buyers.
Along with the two-tone special, Mazda is also showing off the new Skyactiv chassis and engine that'll underpin and power the upcoming next-generation MX-5 (as well as an as-yet-to-be-determined Fiat Group roadster if the two parties can work out their differences). With a lower center of gravity that's also closer to the middle of the car, the new chassis promises even better balance and a good couple hundred pounds of weight savings over the outgoing model. Check it all out in the press releases below.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

Mazda3 with Skyactiv-X engine technology caught testing in the wild

Sometimes, automakers are fine with their mules coming under the watchful lenses of spy shooters. Proof of this can be seen plastered across the bodysides of the Mazda3 mule you see above. Clearly, Mazda wants the world to know that engineers are working hard on the company's so-called Skyactiv-X engine technology so badly that it's created a custom matte black vinyl wrap for its test mules. Clever. Expect to see this sweet new engine tech in the 2019 Mazda3. This SCCI, or Spark Controlled Compression Ignition system holds tremendous potential to boost the efficiency of gasoline-powered engines by 20-30 percent, thereby matching the fuel economy of a comparatively sized diesel engine. As an added bonus, torque figures are expected to jump a similar amount. Besides the placard-sized stickers, there isn't much to see here. The car is clearly a Mazda3 hatchback, though the fenders are punched out a bit and the fuel door is modified from stock. We'd wager that future prototypes will wear a lot more camouflage to cover up next-gen bodywork. In other words, stay tuned.
