Mazda's rotary engine may live on as a range extender (UPDATE)

Update: We received a response from Mazda that confirmed plans for a 2019 electric car available in battery-only and range-extended models, but there was no comment on any other details. The text has been updated to reflect this. It may be time for rotary fans to start getting their hopes up a little for a return of the spinning triangle engine. Automotive News spoke with Mitsuo Hitomi, the man in charge of Mazda powertrains, who said there's a very good chance the next implementation of the rotary engine will be as an electric car range extender. The news source also suggests that such a vehicle could be just around the corner, since Akira Kyomen, Mazda's vehicle development program manager, confirmed to Automotive News that the company will have an EV out in 2019 in both pure electric and range-extended versions. We reached out to Mazda for more information, and a representative confirmed both the pure electric and range-extended models for 2019, but couldn't comment on anything else regarding those vehicles. Looking back, we have reason to believe that this really might happen. As far back as 2013, Mazda was working on a rotary-engine range-extended electric car in the form of the Mazda2 RE Range Extender. It had a total range of 250 miles, half of which came from its battery, the other half from a 330 cc rotary engine generator fueled by a 2.6-gallon gas tank. More recently, Mazda has also teased rotary power with the RX-Vision concept at the 2015 Tokyo Motor Show and another rumored rotary concept at this year's show, which could be the design concept teased recently. But most convincing is the patent we found from Mazda that described a range-extended electric car that would specifically use a rotary engine. The powertrain layout looks just like the one used in that Mazda2 concept. There's also the fact that, as we've previously pointed out, and as Hitomi mentioned to Automotive News, the rotary could be a good range-extender due to its compact size and smoothness. Of course it also isn't known for being the most efficient engine, but if it isn't required to provide all the forward propulsion, it could be made small enough that it's frugal, and the added space and weight savings would be important for making the vehicle more practical, adding more batteries, or simply keeping the car lighter. This news might not excite rotary die-hards who have been waiting for an RX-7 and RX-8 successor, but they shouldn't quite abandon hope yet.

2016 Mazda CX-9 First Drive

Automotive enthusiasts tend to obsess over spec sheets. How else could we know which cars and trucks are the quickest in a straight line, hold the road with the greatest tenacity, or tow the biggest trailers? More succinctly, what ammunition would we have in the seemingly endless back-and-forth of Internet forums if it weren't for specifications? Mazda's engineers think they've found a better way. The 2016 CX-9 has less horsepower than its primary competitors. The only engine available is a turbocharged four-cylinder, hooked to a six-speed automatic. Drivers won't miss the 23 horsepower (or more, as we'll soon explain) lost in the changeover from 2015 to 2016, because Mazda applied its holistic Skyactiv approach to the largest vehicle it offers. That means less weight and, ultimately, more fun. Or so they say. Are they right? Yes. And no. Most of the time, in normal on-road driving conditions, the 2016 CX-9 is the most fun you can have with three rows. But the real-world tradeoff didn't go off completely without a hitch. Reasoning that real-world performance is more important than ultimate horsepower, Mazda specified a four-cylinder for its big, three-row SUV instead of a more traditional V6. Let's get those all-important specifications out of the way: All 2016 Mazda CX-9s are fitted with a 2.5-liter turbocharged four-cylinder with 250 horsepower and, impressively, 310 pound-feet of torque at just 2,000 rpm. Unless you decide to use 87 octane, in which case you'll be limited to 227 horsepower. Mazda doesn't think owners will actually notice the difference in power levels, so there's no Premium Fuel Recommended sticker on the back of the fuel door. Mazda utilized some clever turbo trickery to deliver a diesel-like torque curve from its gasoline-fueled engine, which makes the small-displacement powerplant feel lively at low engine speeds. The flipside is that the CX-9 runs out of breath as the needle swings across the upper reaches of the tach. While that simply wouldn't do for a sportscar like the MX-5, in the CX-9 it's not necessarily a deal breaker. One benefit to the downsized engine is that it doesn't guzzle fuel. The EPA rates the CX-9 at 22 miles per gallon in the city and 28 on the highway. Drop one mpg all around for the all-wheel-drive model. Those figures beat out all the CX-9's most natural competitors, including the Honda Pilot and Toyota Highlander. The turbo-four Ford Explorer matches the 28-mpg highway figure, but loses by three in the city.

Mazda CX-5 Luggage Test | How much cargo space?

We're already seen how Mazda's largest crossover, the CX-9, does at stuffing luggage inside its cargo hold. Now it's time for the next rung down the Mazda ladder. The Mazda CX-5 has 30.9 cubic-feet of space behind its raised back seat, which on paper, is considerably less than its top competition. The Hyundai Tucson leads the way with 38.7 cubic-feet, the Honda CR-V (39.2) and Toyota RAV4 (37.5) are basically the same, and the Subaru Forester has between 33 and 35 depending on options. However, the CX-5 does have more than the Chevrolet Equinox (29.9), Jeep Compass (27.2) and Ford Escape when its sliding back seat is in its aft-most position (33.5 when all the way forward).  Basically, this compact Mazda's cargo area is midpack, which makes it a good choice for my first luggage test of the segment. Let's see how much of the luggage in my garage fits inside. As a refresher, I use two mid-size roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D).  I started by keeping the cargo cover in place to see how much fits underneath it. The answer is the four largest bags. The two smaller ones did not. OK, now let's remove the cargo cover, which is an unusual design. Rather than a roller-type cartridge that you manually pull into place or a rigid hatchback-like unit that rises up when the liftgate goes up, the CX-5 basically combines the two. The forward bit is attached to the liftgate and unspools when opened.  To detach it, you need to unfasten these plastic clamps and then remove the cartridge reel much as you would a normal cargo cover. OK, and now here's how much the CX-5 can fit with the cargo cover removed.  All of it! That above configuration is just the first thing I came up with, but there's likely additional Tetris formations to be found. Note that the tailgate does close here but the middle cases' wheels are awfully close to the window.  I'm not going to stop there, though. I went ahead and rummaged through my garage to see what it would take to fill'er up. There you go: one duffle bag and one gym bag stuffed into the spaces. You could probably fit a grocery bag right in front there, too.
