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.

Car and Driver lists 10Best for 2013, same as it ever was

Forgive us for having the distinct feeling of déjà vu, but it certainly feels like we've been here before. By that we are referring Car and Driver and the announcement of its annual 10Best vehicles for 2013. To be sure, it's an impressive selection of cars that combine heart-pounding performance and frugal sensibilities, but it also represents something of a broken record on the part of C/D. We're not so sure that's a flaw, though, as the resulting list is tough to argue with.
Vehicles like the Ford Mustang, Porsche Boxster, and BMW 3 Series have maintained their high-horsepower spots on this list for several years now. Even on the more practical and nimble end, the Honda Accord, Honda Fit and Mazda Miata have not budged. These continued spots are even in light of redesigns for some vehicles such as the Accord, Boxster and 3 Series.
In fact, the only newcomer to the 10Best list this year are the Scion FR-S/Subaru BRZ twins, which knocked out the Cadillac CTS-V. We think it would have been a huge misstep to have excluded the FR-S/BRZ, even in light of the supercharged Caddy's lamentable departure from 10Best.

Mazda-Toyota partnership has us dreaming of a rotary hybrid

As you may have seen, Mazda and Toyota are going to be working a little more closely with each other. In their announcement, the two companies said they'd be building an American assembly plant together, and working on electric vehicle technology. But one of the companies' goals got our mental gears turning: It's listed as "Expand complementary products," and it's left very open-ended. The companies say they "will further explore the possibilities of other complementary products on a global level." These are in addition to Mazda providing the Mazda2 to Toyota as the Yaris iA, and Toyota providing Mazda a commercial van to sell in Japan. So what could these future complementary products be? We have a couple of ideas, one that's ludicrous but awesome (and, sadly, probably won't ever happen), and the other grounded in reality. Let's start with the fun one. What's the one thing Mazda fan has been wanting for years? A rotary sports car, of course! And while Mazda has repeatedly said that it has a small band of engineers plugging away at the spinning triangle problem, the odds of Mazda putting it into production have been slim. The inherent thirst of the rotary would make it tough to introduce when fuel economy regulations have been tightening. Plus, Mazda is a small company that needs to stretch every dollar, and having a one-off engine not based on anything else would be expensive. How could Mazda get around these obstacles? This is where the partnership with Toyota comes in, in our long-shot fantasy. Aside from having deep pockets, Toyota has a wealth of knowledge in the realm of hybrids. Thus, why not a rotary hybrid? Electrifying their oddball motor would fix two issues. One is obviously the fuel economy, since the gas engine wouldn't have to run all the time. The other is in providing torque. Rotaries infamously have little torque, especially down low, so adding an electric motor would allow this hypothetical rotary sports car to have a grunty low end, while still providing the Everest-high redline rotary fans like. The idea would be sweetened with the solid-state batteries that Toyota is developing, which could provide lots of electricity without weighing a ton. The rotary-electric mashup notion isn't totally alien to Mazda, either, since the company created an electric Mazda2 with a rotary engine for a range extender — albeit for different reasons. The company even filed a patent for the rotary range extender recently.
