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

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.
