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.

Living Life Large: Driving $2 million worth of cars in one week

Monterey Car Week has quickly become one of my favorite events of the year. There's something for everyone – classic car shows, modern concepts and new vehicle debuts, auctions, racing, and so much more. From a media perspective, there's also a chance to drive a ton of cars. Many automakers bring their latest wares out to Monterey for us to test during our limited free time, and it's a great opportunity to experience fantastic metal against a gorgeous backdrop. That's exactly what I did this year. Instead of flying into Monterey and being driven around, my journey started in Los Angeles and ended in Napa, and I managed to get behind the wheel of some $2 million worth of new cars. Some were old favorites, and many were new experiences. But looking back, this was one of the best weeks of driving I've had in years. Rather than try to come up with some common arc to tie these cars together, here are my notes on all the cars I tested in California earlier this month, presented in the order in which they were driven. 2016 Mazda CX-3 The CX-3 pictured here isn't the exact one I drove in California, but it's close. The only difference was color – my delivered-to-LAX tester wore Mazda's awesome new Ceramic hue (pictured below on the MX-5 Miata). I used the CX-3 to slum through crummy Los Angeles traffic for two hours on the way out to Santa Barbara, with a quick stop at In-N-Out Burger on the way for good measure. A lot nicer inside than I remember. Everyone praises Mazda for its excellence in engineering and design, but there's a lot to be said for the improvements in overall interior refinement. Quiet, comfortable, and well-equipped; the CX-3 made sitting on the 405 freeway a lot more pleasant. Not all that functional. I had a hard time fitting a week's worth of luggage for two people inside. The cargo area and rear passenger compartment were filled, with only enough room on top to see out the back window. A Honda HR-V would've swallowed all that luggage with plenty of room for more. So good to drive. Not surprising, since this wasn't my first time in the CX-3. I knew this CUV would be good on twisty roads, but on the highway it's really exceptional. Road and wind noise are minimal and the overall ride quality is a comfortable sort of sporty. This is definitely something I could drive every day – it's enjoyable during commuting and entertaining on more interesting roads.

Japan may aid carmakers facing U.S. tariff threat

TOKYO — Japan is considering giving carmakers fiscal support including tax breaks to offset the impact from trade frictions with the United States and a sales-tax hike planned for next year, government sources told Reuters on Wednesday. Going into a second round of trade talks with the United States on Sept. 21, Japan is hoping to avert steep tariffs on its car exports and fend off U.S. demands for a bilateral free trade agreement that could put it under pressure to open politically sensitive markets, like agriculture. "If the trade talks pile pressure on Japan's car exports, we would need to consider measures to support the auto industry," a ruling party official said on condition of anonymity because of sensitivity of the matter. The auto industry accounts for about 20 percent of Japan's overall output and around 60-70 percent of the country's trade surplus with the United States, making it vulnerable to U.S. action against Japanese exports. Japan's biggest automakers and components suppliers fear they could take a significant hit if Washington follows through on proposals to hike tariffs on autos and auto parts to 25 percent. Policymakers also worry that an increase in the sales tax from 8 percent to 10 percent planned for October 2019, could cause a slump in sales of big-ticket items such as cars and home. Prime Minister Shinzo Abe has twice postponed the tax hike after the last increase from 5 percent in 2014 dealt a blow to private consumption, which accounts for about 60 percent of the economy. To prevent a pullback in demand after the tax hike, the government may consider large fiscal spending later when it draws up its budget for next year, government sources said. "One option may be to greatly reduce or abolish the automobile purchase tax," one of the government sources said. The government is also considering cuts in the automobile tax and automobile weight tax to help car buyers, the source added.
