Mazda CX-3 to be diesel-only in Japanese home market

Diesel power. It's not just for Europeans anymore. In fact, when Mazda introduces its new CX-3 compact crossover to its home market of Japan, the model will be exclusively diesel-powered, Reuters says, citing remarks made by Mazda CEO Masamichi Kogai. Consistent with its recent push for better fuel economy, Mazda is embracing diesel power as a way to boost fuel-economy for cars that may be larger than the compact variety. Mazda, which plans to make about 150,000 gas- and diesel-powered CX-3s for global consumption per year, is pricing the diesel CX-3 at about $20,000 in Japan. Diesel sales accounted for less than three percent of new-vehicle sales in Japan last year, so there's a risk to Mazda's strategy. But the automaker, which is the fifth-largest in Japan, says performance and noise (and smoke) issues largely associated with diesel powertrains in the past have largely been eliminated. In all, Mazda expects worldwide sales for the year ending March 31 to rise almost five percent from a year earlier to about 1.4 million units. Mazda showed off an early version of the CX-3 at the Los Angeles Auto Show last November, though North American versions of the model will indeed be gas-powered.

Japanese automakers welcome North American trade deal, fear what's next

TOKYO — Toyota, Nissan and Mazda welcomed on Tuesday the revised North America trade deal that left Japanese automakers unscathed, but they may face a bumpy ride when Washington and Tokyo hold new talks on over $40 billion of annual U.S. auto imports from Japan. The United States and Canada reached an agreement on Sunday to update the 1994 North American Free Trade Agreement after Washington had forged a separate trade deal with Mexico in August. The updated deal effectively maintains the auto industry's current footprint in North America, and spares Canada and Mexico from the prospect of U.S. national security tariffs on their vehicles. Mazda, which ships cars to the United States from Mexico and Japan, called the deal a "big step forward". Nissan, which makes the cars it sells in the United States locally as well as in Mexico, Japan and other countries, said it was "encouraged" by the agreement. Toyota, Japan's biggest automaker, said it was "pleased" that a basic deal was reached. Other automakers were not immediately available for comment. While the deal has removed the risk that the disintegration of the pact would have posed to automakers, bigger risks loom large for Japanese firms as a chunk of the roughly 7 million cars they sold in the U.S. last year were shipped from Japan, and a trade deal between Washington and Tokyo has yet to be agreed. The United States and Japan last week agreed to begin fresh trade talks, with U.S. President Donald Trump seeking to address Japan's $69 billion trade surplus, of which nearly two-thirds comes from auto exports. Washington is also investigating the possibility of slapping 25 percent tariffs on auto imports on national security grounds, although it has agreed with Japan to put any new tariffs on hold during the talks. Analysts say the United States may take a tougher stance on auto imports from Japan than from its neighbors. "If Japan requests an exemption from the 25 percent tariffs under consideration, Washington could propose a more strict cap on imports than it agreed to with Mexico and Canada," said Koji Endo, senior analyst at SBI Securities. "That would be a risk." This could be a big blow to Japan, as the United States is a key source of revenue for Japanese automakers including Toyota, Nissan and Honda. The U.S. market accounts for a quarter or more of their annual global vehicle sales, and of their total U.S.

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.
