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.

Mazdaspeed2 supermini hot hatch under consideration

Though the Ford Fiesta ST and Fiat 500 Abarth (and arguably the Mini Cooper S) may stand pretty much alone in the North American market, in overseas markets, supermini hot hatches are a big deal. Unfortunately, challengers like the Volkswagen Polo GTI, Seat Ibiza Cupra and Renault Clio RS 200 Turbo never make it to our showrooms, but word has it that there's soon to be a new entry on the market.
That would be the Mazdaspeed2, which would be badged in certain markets as the Mazda2 MPS. Speaking with Australian site CarAdvice.com.au at the launch of the Mazda2 on which it would be based, the Japanese automaker's global sales chief and the hatchback's deputy product manager hinted that such a product is definitely being discussed, even if it hasn't yet been approved.
This wouldn't be the first time such a notion were entertained, as Mazda has shown numerous performance concepts based on the previous Mazda2/Demio over the years, but none have come to fruition.

2014 Mazda CX-5 with 2.5-liter Skyactiv engine

Back in October, we compared the relative merits of two new and very good small crossovers: the 2013 Ford Escape and 2013 Mazda CX-5. The CX-5 we tested then had Mazda's 2.0-liter Skyactiv-G engine under its hood, and it managed to just edge out the EcoBoosted Ford despite being down by some 23 horsepower and 34 pound-feet of torque. Had it been available, the 2.5-liter Skyactiv engine that we recently had the opportunity to try out in the 2014 Mazda CX-5, it may have made that comparison even easier to call in the Japanese CUV's favor.
Clearly, if you're in the market for a reasonably sized crossover, the CX-5 should, at the very least, be on your test-drive list. The new engine offering will let buyers opt for a stronger powerplant, with 184 hp and 185 lb-ft on tap. On our second day in Austin's Hill Country - the first was spent quick-spinning the 2014 Mazda6 i Sport, you'll recall - we covered a couple of hundred miles and put the new CX-5 through its paces; here's what we turned up.
