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 A newer version of this story appears here.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 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.

2016 Mazda MX-5 Miata Club long-term wrap-up | Farewell, fun friend

About one year ago, we took delivery of a 2016 Mazda MX-5 Miata. We made sure we got the sportiest version we could, the Club model (which includes Bilstein shocks, a limited-slip differential and a front shock tower brace) with optional BBS wheels and Brembo brakes. We also sprung for the appearance package to give our cute little roadster a modicum of aggression. It was a tad pricey at $32,835, but we enjoyed every minute of it. Well, almost every minute of it. It's not a perfect car, as it's loud and stiff on the highway, and we ran into an issue in which the top had to be replaced (under warranty). But minor grievances aside, just about everyone who drove the little roadster came back with a smile, especially when we took it to a racetrack. Below are final thoughts on the car from our editors. Senior Green Editor John Beltz Snyder: This car is about as car as any car gets. It's so car! That is to say, it's pure in its mission and in its effective execution as a driver's plaything. Its crisp steering, snickety six-speed manual gearbox, and rev-happy engine create the wonderful sensation that you're driving faster than the speedometer reads. Normal speeds never felt so heroic. The view out the front is fantastic, too, and the curves of the hood are nothing short of inspiring as they frame the road ahead. I don't care that it's noisy, jarring, and ergonomically weird. Old and British in spirit, it offers a level of engagement that's hard to find in a new car, especially for under $30,000. Anyone who has a Miata in their stable isn't lucky. They're smart. Senior Editor Alex Kierstein: I'm a bit embarrassed to think back to my first impressions about driving the MX-5 now that I've had so much seat time in this one. While I loved the idea of it as a throwback to the original NA Miata from the moment it was revealed, I was a bit turned off by how civilized it was. And how quick it was. No longer a momentum car, the new MX-5 seemed more forgiving of bad gear selection or a bad corner entry. I felt like something had been removed, a ragged edge, some everyday engagement. Well, a year on, and my feelings have changed. If you stop comparing it directly to the (slow, weedy, rattly, uncomfortable) first- and second-generation cars, it's a brilliant little roadster. I miss the raw edge less and enjoy the livability more — the raw edge was really just a lack of civility. A flaw that forced you to engage with the thing every moment.
