Toyota and Mazda in talks to build joint US auto plant

UPDATE: The Toyota-Mazda deal has been announced. A newer version of this story appears here. Toyota Motor Corp and rival Mazda Motor Corp are expected to announce plans on Friday to launch a joint venture and build a new U.S. assembly plant, a person briefed on the matter said. A new auto plant would be a major boost to U.S. President Donald Trump, who campaigned on promises to boost manufacturing and expand employment for American autoworkers. Japan's Nikkei reported on Thursday that Toyota would take a roughly five-percent stake in Mazda Motor Corp to develop key electric vehicle technologies and jointly build a factory in the United States. The deal could be announced as soon as Friday, the newspaper said. The person briefed on the matter, who was not authorized to speak to the media and requested anonymity, confirmed the Japanese carmakers were planning to build a large plant in a yet to be determined U.S. location and planned future joint efforts on electric vehicles. The same source declined to offer further details, however. Toyota, in a statement, said the two companies have been exploring various areas of collaboration under a May 2015 agreement. "We intend to submit a proposal to our board of directors today regarding the partnership with Mazda, however, we would like to refrain from providing further comment at this time," Toyota said in a statement issued by its U.S. operations. Mazda said in statement that "nothing has been decided yet" and added the company "will have a board meeting on this matter today. We cannot comment any further." Toyota, the world's second-largest automaker by vehicle sales in 2016 and Japan's dominant car company, has been forging alliances with smaller Japanese rivals for several years, effectively consolidating the Japanese auto sector. A new U.S. assembly plant would likely become the prize in a fierce competition among Midwestern and Southern states eager to expand manufacturing jobs. Trump in January criticized Toyota for importing cars to the United States from Mexico. The Republican president also threatened to impose a hefty fee on Toyota if it were to build its Corolla cars for the U.S. market at a plant in Mexico. "Toyota Motor said will build a new plant in Baja, Mexico, to build Corolla cars for U.S. NO WAY! Build plant in U.S. or pay big border tax," Trump said in a post on Twitter. But since January, Trump has praised Toyota for its U.S. investments.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

2016 Mazda MX-5 Miata in motion for the first time

By now, you've already poured over the details (however few there may be) and images of the 2016 Mazda MX-5 Miata. For us enthusiasts, it's arguably the most important new car debut of the year, and for Mazda, it marks the 25th anniversary of its iconic roadster - something that's being celebrated all weekend long out in Monterey, CA.
Our resident Miata owner, Chris Paukert, is out in sunny California and just passed along this video, showing all four generations of the MX-5 in motion (slowly), on the road at Mazda Raceway Laguna Seca. This is the first time the 2016 MX-5 has been shown driving under its own power, and it will join a wealth of other roadsters as Mazda attempts to break the world record for most Miatas in one place at one time.
Have a look at the emailed-from-an-iPhone-quality video above, and then take a moment to read Paukert's own notes from the ND Miata's live showing earlier this week, here.
