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.

Junkyard Gem: 1988 Mazda 323 GTX

Back in early 2007, when the late Davey G. Johnson got me my first job writing for an automotive publication (well, unless you count writing for the Year One catalogs back in the mid-1990s) and I took on this goofy pen name for real, I didn't quite grasp that any readers might be interested in the stuff I saw during my frequent junkyard trips. So, when I took my crappy Nikon Coolpix 2500 to the now-defunct Pick Your Part in Hayward, California, and saw a super-rare Mazda 323 GTX among all the Tercels and Rabbits in the IMPORTS section, I just took a few shots of this interesting car for my own enjoyment. These days, I'll take more than 100 photographs of a junkyard car of such great historical significance, editing them down to the best couple of dozen, but in March of 2007 I got just three of the 323 GTX. Robert Capa had his Magnificent Eleven at D-Day, and I've got the Magnificent Three of the GTX. Here they are. Any Mazda 323 of the immediate post-GLC era is a real junkyard rarity today, but Mazda sold very few of the all-wheel-drive, turbocharged homologation-special 323s over here during the 1988 and 1989 model years. A mere 1,243 of these cars made it to North American streets. Back in 2007, they weren't worth much (in fact, they still aren't incredibly valuable, if we go by Bring a Trailer real-world sale prices), and so this one showed up in El Pulpo's yard. These cars wouldn't be considered particularly fast by 21st-century standards, now that we've had decades of street-legal Mitsubishi Lancer Evos and Subaru WRXs flinging snow and mud around, and they tended to grind their powertrain components into a costly oil-and-metal-shaving slurry. But they were maniacally cool in the late 1980s, and that's enough. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Mazda teases a new compact SUV for Geneva

Mazda waited until the lights were out to tease the tidy rear end of a brand new crossover. The Japanese automaker didn't say much about the model that will debut at the Geneva Motor Show next month, only calling it "a brand-new addition to the Mazda lineup," and "the second model in new-generation lineup." We're going to put our chips down on this being the next CX-3 crossover, which has been predicted to arrive by 2020. If that's so, we can expect a larger model than the one currently on sale. The present, first-gen CX-3 rides on the Mazda2 platform. The coming CX-3 will use the Skyactiv Vehicle Architecture supporting the new Mazda3, growing out of the subcompact class into the compact segment. According to one report last year, the extra girth is a play for better sales in the U.S. market. In 2017, Mazda sold more CX-3s in Australia than in the U.S. The stronger, stiffer platform will introduce Mazda3's delights such as the human-centric interior ergonomics, and hopefully the same driving dynamics that we called "the life of the compact sedan party" in our Mazda3 First Drive. Yes, that's all but certain to mean a torsion beam rear suspension, which was said to have been done for NVH reasons after Mazda said it "got a lot of complaints from the media" over the multi-link rear. The engine lineup should mirror the Mazda3 in the U.S., being the naturally aspirated 2.5-liter four-cylinder at launch, followed by the Skyactiv-X. We can probably expect more teasers before Geneva press days kick off on March 5. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
