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.

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.

2019 Mazda CX-5 Turbo First Drive Review | Two-row crossover perfection

Listen: If you're shopping for a crossover, and by all accounts most Americans are, there is no better option on the market than the 2019 Mazda CX-5. When we test drove the all-new 2017 CX-5, we were astounded by its marked improvements over the already-great previous generation. We noted then its biggest drawback was its average 187 horsepower. The CX-5 didn't feel slow, and it certainly made up for it in other ways, like by delivering superior road-hugging abilities. But, it was probably enough to turn off buyers who do their shopping by analyzing spec sheets. For 2019, Mazda addressed that exact issue with a vengeance. With an all-new 2.5-liter SkyActiv Turbo good for 250 horsepower, the CX-5 not only leapfrogs bestselling rivals like the Honda CR-V and Toyota RAV4, but lands squarely in the realm of luxury stalwarts such as the Audi Q5 and BMW X3. When we drove the 2017 CX-5, we likened the handling to that of a Porsche Macan. Now it has the power to match. Among its direct competition, only the 2019 Toyota RAV4 breaks the 200-horsepower mark, ringing in at 203 (and the Hybrid makes an even more impressive 219 ponies), while the Honda CR-V, Subaru Forester and VW Tiguan all sit between 180 and 190. Now, to get the full herd you must fill the tank with 93 octane premium, but if you don't mind leaving a few ponies in the stable you can pump 87 octane for a slight dip to 227 horsepower. The engine adjusts with no ill effects. Even better, torque stays the same no matter what, and the stump-pulling 310 pound-feet of torque comes quick at just 2,000 rpm. The SkyActiv turbo is full of clever engineering tricks, too. There's an exhaust port restrictor, for instance, a narrower channel used only at low engine speeds. Mazda engineer Dave Coleman likened it to a thumb over a firehose, making more exhaust pressure at idle to spool up the turbo, and thus delivering more oomph when you take off from a standstill. Mazdafarians will recognize the mill as the same one that debuted on the 2018 Mazda6. It powers the CX-9 too, Mazda's highly acclaimed three-row crossover. The 3,825-pound CX-5 has 558 fewer pounds to shuffle around than its larger stablemate, making it downright snappy. However, that extra pep does come with a fuel economy penalty, 22 city and 27 highway mpg versus the naturally aspirated version's 24 city and 30 highway mpg.
