Trump declaration they're a security threat stuns Japanese automakers

TOKYO — Japan's automakers' lobby said on Tuesday it was dismayed by President Donald Trump's declaration that some imported vehicles and parts posed a threat to U.S. national security, as the industry braces for a possible rise in U.S. tariffs. Trump made the unprecedented designation of foreign vehicles on Friday but delayed for up to six months a decision on whether to impose tariffs to allow for more time for trade talks with Japan and the European Union. "We are dismayed to hear a message suggesting that our long-time contributions of investment and employment in the United States are not welcomed," said Akio Toyoda, chairman of the Japan Automobile Manufacturers Association. "As chairman, I am deeply saddened by this decision," Toyoda, president of Toyota, said in a statement. Trump has threatened to impose tariffs of up to 25% on imported cars made by foreign automakers, a move which automakers have argued would ramp up car prices, curb the global competitiveness of U.S.-made vehicles and limit investment in the country, the world's No. 2 auto market. The United States is a vital market for Toyota, Nissan, Honda and other Japanese car makers. Autos and components are among the Asian country's biggest export products. Most of Japan's major automakers operate plants in the United States. The Japan Automobile Manufacturers Association notes that its automakers build about 4 million vehicles a year in North America, or 75 percent of what it sells here. Many are built for export, helping lessen the U.S. trade deficit Trump is concerned about. Major automakers have announced a slew of investments in the United States since Trump took office in January 2017 and put pressure on the industry to create more U.S. jobs. For its part, Toyota has pledged to invest almost $13 billion in the United States between 2017 and 2021 to boost manufacturing capacity and jobs. This includes $1.6 billion for a vehicle assembly plant in Alabama jointly run with Mazda. Government/Legal Honda Mazda Mitsubishi Nissan Toyota Trump

Mazdaspeed3 concept tipped for Frankfurt debut

The last quarter of 2015 could be a big one for Mazda as a report has emerged from Australia claiming that the company will come to the Frankfurt Motor Show in September with a near-production concept of the third-generation Mazdaspeed3, while a second-generation CX-9 will be shown a few months later in Los Angeles. Motoring.com.au ran the initial report, and although the news seems plausible, the outlet doesn't provide sources for either piece of news. Likewise, our friends at Mazda USA refused to comment on "speculation." Speculation it may be, but it's surely tantalizing considering the recent popularity of both the hot hatch and three-row crossover segments. According to the Aussies, the concept Speed3 will quickly evolve into a production model, which will launch alongside a mid-cycle refresh for the current 3. A turbocharged 2.5-liter will spit out 295 horsepower, and could have all-wheel drive. Even if only the front axle is doing the work, the MS3 will easily be able to stand toe-to-toe with hotter half of the segment based on output alone. As for the more mundane offerings, Motoring reports the long-in-the-tooth CX-9 will get a replacement in LA, although it doesn't offer much in the way of details beyond that. It should be interesting to see how the company's Skyactiv philosophy will be implemented on such a large vehicle. Perhaps the biggest surprise from the Australian report, though, are the outlet's reports on the CX-7, which will return sporting a third row of seats after its larger sibling debuts. That'd give Mazda a versatile lineup of four crossovers, with the sub-compact CX-3, the compact CX-5, the midsize, seven-passenger CX-7 and the fullsize CX-9. As we weren't able to confirm any of this with Mazda, we'd still warn that this news should be ingested with grains of salt. Still, it looks like the company could be set to make some waves in the first two shows of the upcoming auto show season.

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.
