A tough choice: 2017 Honda CR-V vs. 2017 Mazda CX-5

One has to feel for the typical new-car buyer. The one not reading Autoblog and the one who recognizes a V8 as vegetable juice. For them, picking between compact crossovers must seem like choosing between various identically sized cardboard boxes. Which one do you want? "Ah, I'll take the one with the best deal." Except, with the 2017 Honda CR-V and now the 2017 Mazda CX-5, Joe P. Everyman has a chance to choose between two vehicles that are quite clearly different, yet also clearly leaders in what they do. Everything else seems like alternatives based on price or perhaps off-road readiness (Jeeps Compass and Cherokee, perhaps a Subaru Forester). As scheduling would have it, a 2017 CR-V Touring just happened to be sitting in my garage the week I was set to drive the new CX-5 Grand Touring in San Diego. This isn't a complete, scientifically enacted comparison test, but there was enough drive time in close succession on the same roads and with similar price tags to draw conclusions. At its simplest, the CX-5 is the best choice for the driver while the CR-V is the best choice for everyone else aboard. That's not to say they are myopic in those classifications – the CX-5 could still ably handle family duty, while the CR-V is impressively well-rounded to drive in a way that shouldn't turn off those seeking some driving involvement. However, each has a clear focus that sets it down a different path toward different target buyers. Let's start with the newer kid on the block from Mazda. It is best suited for the person whose life changes have dictated the switch from an agile car to some sort of family hauler. Its spot-on steering and throttle response evoke Porsche, while the six-speed automatic transmission favors performance over fuel economy (while still getting really good fuel economy). Those dynamic elements, plus a carefully crafted, ideal driving position should make the CX-5 feel "just right" for those used to more sporting, non-family-oriented transport. Inside, the latest CX-5 boasts a handsome, upscale design with materials to match. Aesthetically, to these eyes at least, it's the best of a crowded bunch. Quality-wise, only the also-impressive CR-V would seem to come close. Along with the slick new exterior, the cabin conveys the more premium vibe that Mazda was shooting for with the new CX-5 – it also makes a more emotional connection than the typical cardboard box on wheels.

2019 Mazda CX-5 Signature AWD diesel unveiled in New York

NEW YORK —It seems like we've been waiting forever, but the wait is finally over. Mazda has finally launched a diesel version of the CX-5 for the U.S. market, unveiled at the 2019 New York International Auto Show. Specifically, the 2.2-liter Skyactiv-D turbo-diesel engine will be offered in the higher-end CX-5 Signature AWD, part of what Mazda calls its "path to premium," as the company continues to set its sights on some of the more expensive competition. The Skyactiv-D 2.2 makes use of a sequential twin turbocharger that employs a smaller turbocharger first at low rpm for quick throttle response, after which a valve opens to spool up a larger turbocharger at higher rpm. Mazda says this provides "smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque." Mazda estimates the output of the engine to be 168 horsepower at 4,000 rpm and 290 pound-feet of torque from a low 2,000 rpm. The engine has a rev limit of 5,500 rpm. As of right now, it's only in the all-wheel-drive version and only in the Signature trim level. As such, it gets a ho-hum EPA fuel economy rating of 27 mpg city, 30 highway and 28 combined. We previously saw fuel economy figures for a potential front-drive diesel CX-5 getting just slightly better fuel economy, at 28 city, 31 highway and 29 combined, but no word yet on if and when that'll be made available. The mediocre diesel fuel economy, while expected given the midstream shift from one emissions strategy to another, is particularly disappointing in context. The non-turbo CX-5 AWD, which makes 187 hp and 186 lb-ft, gets 24 city and 30 highway for 26 combined mpg – just 3 mpg less in the city and 2 mpg less overall than the diesel. The much more powerful CX-5 Turbo, which makes 250 hp and 310 lb-ft, gets 22 city, 27 highway, and 24 combined. Mazda is taking pre-orders for the 2019 CX-5 Signature AWD with Skyactiv-D 2.2 starting now, at an MSRP of $42,045, including $1,045 in destination fees. We have to point out that this is a sizable jump in MSRP from a CX-5 Signature AWD with the more powerful turbo engine, which lists for $38,235 – a $3,810 difference in fact. Given the lackluster fuel economy and considerable decrease in power and torque, we're concerned that the diesel may be a tough sell at this sort of premium.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
