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.

Mazda Hazumi concept presages next Mazda2

Looks like Mazda's big Geneva Motor Show debut is actually something quite small. Teased here, the Hazumi concept "points the way to the future" for the brand's subcompact offering, the Mazda2. Details are slim as of this writing, but from what we can see in the image above, the Hazumi will use the same Kodo design language found on the Mazda3, Mazda6 and CX-5. We're big fans of this styling direction, so we fully expect the concept to be quite an attractive little number.
Hazumi means "bound" or "spring up" in Japanese, with Mazda saying this nomenclature is "particularly well-suited to a small car that appears to be bursting with energy." In other words, say goodbye to the friendly faced Mazda2 we've enjoyed since it launched in the United States in 2010. Instead, prepare for something decidedly more assertive, hopefully improving upon the already-great driving dynamics of the current subcompact. If we're honest, we can't wait.
Mazda will also use the Geneva show to debut its new small-displacement, 1.5-liter Skyactiv-D diesel engine. The automaker hasn't confirmed that this new fuel-efficient powerplant will be part of the Hazumi concept package, but considering the two are debuting alongside each other, it would seem to make sense. As for whether or not this engine could come stateside when the next Mazda2 launches, we're not holding our breath for that, especially considering the company's current woes with US-spec diesel engines.

Why the 38-mpg 2014 Mazda6 is on dealer lots, but you can't drive it

If you stop by your local Mazda dealer this month, with any luck, you'll see the much-anticipated 2014 Mazda6 parked in the showroom - there are already a few hundred of them out there. That's quite an accomplishment in light of the fact that it isn't even calendar year 2013. The move is part of a strategic decision by the Japanese automaker, which is hoping to capitalize on holiday showroom traffic. (The last five days of the year are typically among the busiest dealer days all year).
If you happen to spy the rakish sedan, you may notice something missing - a window sticker. That's because Mazda (like other automakers) can't legally display the Monroney on a 2014 model year vehicle until January 1, 2013. According to Autoblog sources, Mazda dealers are legally prohibited from letting you test drive until the start of 2013, so it's more of a sneak preview than anything else. Even so, we reckon shoppers will be impressed when they finally get a look at those window stickers - Mazda hasn't announced fuel economy figures yet, but Autoblog has learned that the 2014 model will carry a pair of impressive numbers: EPA estimates of 27 miles per gallon in the city and 38 mpg on the highway using regular gas.
