Mazda delays US launch of Skyactiv-D engine

Japanese automakers haven't lead the charge towards diesel power in the same way as, say, the Germans have. But Mazda is out to change that. It has been following Audi's lead on the racetrack with oil-burning racecars right here in America, and will soon translate that excitement to the road by introducing its Skyactiv-D engine in North America. It just won't happen as soon as we expected.
Mazda announced today that, while its diesel engine meets current emissions requirements, the company has decided once again to push back an introduction originally slated to kick off in the Spring. According to the brief statement below, Mazda wants to take more time to find "the right balance between fuel economy and Mazda-appropriate driving performance."
In other words, the Zoom-Zoom brand apparently thinks its diesel engine doesn't deliver the zoom-zoom American drivers would expect, so we'll have to wait just a little bit longer. Details to follow closer to launch, whenever that will ultimately take place.

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.

Next Mazdaspeed3 could look this good

Mazda showed off its brand-new 2014 Mazda3 at an event in New York City earlier this week, and we have to say, at first blush, we're pretty impressed. It looks fantastic - like a smaller, hatch'd version of the already sleek Mazda6 sedan that went on sale earlier this year. And with a 200-pound weight reduction, efficient Skyactiv gasoline engines underhood and Mazda's usual focus on driving dynamics above all, we're willing to bet that the new Three will be a pretty decent steer.
Of course, being enthusiasts, we're already setting our sights on the next-generation Mazdaspeed3, rendered here by artist Theo Chin. To our eyes, it's not a very imaginative transformation, but is likely a spot-on rendering for what the next car will look like. And it's really, really hot.
While Mazda hasn't exactly confirmed that the new Speed3 will be coming, sources within the automaker have indicated that a third-generation version of the MS3 is under development. Thing is, the Japanese automaker wants to give the standard Mazda3 some time to grow in the market, so we might not see the new Speed3 until something like 2016, with a possible diesel version to arrive before then.
