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 Skyactiv-Hybrid and CNG Concept shown in Japan

Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
The end result of the Skyactiv-Hybrid is fuel consumption estimated at something like 74 miles per gallon.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand, and the company believes this new powertrain will add valuable breadth to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle, capable of running on either natural gas or gasoline. In fact, we're told that the high compression ratio (14:1) inherent in Skyactiv-technology gasoline engines makes conversion to CNG particularly simple.

2016 Mazda MX-5 Miata to make video-game debut next week in Forza Horizon 2 [w/video]

We've driven the all-new, fourth-generation Mazda MX5 Miata. Have you? Well, probably not. With the new roadster not set to hit dealerships until later this year (at the earliest), you might be stuck waiting a bit to climb behind the wheel of the highly regarded two-seater. Of course, if you happen to own Forza Horizon 2, your wait will be significantly shorter. And it'll be absolutely free to boot. The new convertible will make its video-game debut as part of a four-vehicle car pack for the open-world racing title. Downloads will start on March 17. Alongside the new MX-5, the Mazda car pack will also add representatives from each of the roadster's first three generations. Repping the NA will be the 1990 MX-5. The second-generation NB will be represented by the turbocharged 2005 Mazdaspeed MX-5, while the NC will arrive in the form of the Super 20 Concept, shown back at the 2010 SEMA Show. On top of the new vehicles, gamers will also have a chance to win a 2016 MX-5 as part of the new Mazda MX-5 Challenge. Running from March 17 to April 30, those interested in a free Mazda will need to lap its virtual counterpart around the Sisteron Perimeter Sprint Circuit, with the two fastest drivers slated to take part in a head-to-head race in June. The winner will walk away with their very own 2016 MX-5. Oh, and as a final juicy tidbit, the press release clearly states that the Miata weighs in at just 2,332 pounds – just a smidge more than the original NA. (That's with the manual transmission, of course – automatic cars are said to weigh 2,381 pounds.) You can get more specific details on the contest, as well as read more about the car pack, in the attached press release. Check out the release, as well as a preview vid of the MX-5 Car Pack.
