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.

2016 Mazda CX-5 [w/video]

It's difficult for me to get excited about crossovers. I try hard not to be the stereotypical car guy: ignoring the fact that the rest of the world loves these tall hatchbacks, while yelling, "station wagons make more sense!" until I've voided my lungs of air. Deep down I am that guy, but I work around it. Historically the Mazda CX-5 is one crossover that has been quasi-immune to my knee-jerking. It doesn't weigh two tons, offers a manual transmission (in poverty spec, but still...), and looks faster than its competitors. Most importantly, the CX-5 can round a corner without wobbling like a Slinky at the top of the stairs. No item on that list of plaudits would likely crack the top ten "desirables" for average small CUV shoppers. So, for the 2016 update, Mazda instead upgraded the in-cabin experience along with the requisite nips and tucks to the exterior. I borrowed a 2016 model CX-5 to see whether or not those concessions to comfort affected the car-nerd stuff. And to see if the Mazda could still be my go-to CUV recommendation. Driving Notes The engine options are unchanged for 2016. You can still have the fine, 2.5-liter four-cylinder engine, with its 184 horsepower and 185 pound-feet of torque, or its wimpier 2.0-liter lil' brother. My fully spec'd Grand Touring came with the bigger engine, which feels adequately powerful for the class, but not quick. In an era where turbocharged engines are everywhere, revving the Skyactiv 2.5-liter up to its torque peak at 3,250 rpm takes some commitment. I'm annoyed that there's no manual offered with the 2.5L (a combo I can have in both the Mazda3 and Mazda6), but I don't hate the automatic transmission. The six-speed unit is unobtrusive 99 percent of the time; something I regretfully can't tell you about certain nine-speed autos. There are no paddles to play with, but you can tap the shift lever up and down if you're struck by a need for total control. With a new center console and dash, and the addition of the Mazda Connect infotainment system, the '16 CX-5 feels like a new vehicle from behind the wheel. An attractive, pliant, leatherish material swaths the neat console and surrounding real estate. And the perforated leather seats feel damn near upscale. I think that Mazda Connect's version of the central control knob (with handy adjacent volume knob) is almost luddite-proof in its simplicity. There's no latency between twisting and reaction on the screen.

Which car companies are creating new jobs in America?

Since January, automakers have announced investments totaling $9.5 billion in U.S. plants, creating or retaining more than 12,000 jobs. Some of those companies have yet to announce just how many jobs will be created given their investments, with the location of many of those jobs still to be determined. Specifically, the 4,000-job Toyota-Mazda joint venture plant still hasn't announced its location, with numerous states jockeying for it. Hyundai has plans to invest $1 billion but has not announced a jobs number yet. And likewise Ford is investing $1.2 billion in Michigan without specifying a number of jobs. Volvo this week announced plans to add a second line to its factory under construction in South Carolina, spending another $500 million and adding 2,500 jobs to the 2,000 it was already trying to fill. Then Thursday, Daimler announced a $1 billion expansion to its facility in Tuscaloosa, Ala., to produce EV batteries and electric SUVs, a move that will add 600 jobs to its hiring this year. Above, we've created a handy pie chart showing you which companies have announced new jobs and how many there will be.
