Mazda planning more powerful MX-5?

The new Mazda MX-5 will be available with a 1.5-liter four with 129 horsepower or 2.0-liter with 155. And while either engine may seem a tad on the small side for a sports car, they keep perfectly in line with what the Miata is all about. That doesn't mean, however, that more powerful options aren't under consideration. Speaking with Motoring.com.au at the launch of the new MX-5, Mazda's global PR chief Kudo Hidetoshi revealed that two options are under consideration. One would be a larger engine, and the other a turbocharged version of the existing 2.0. The former option would deliver the extra punch while keeping things naturally aspirated and free from turbo lag, but could throw off the weight balance Mazda has worked so hard to preserve. The more likely option, then, would be the turbocharged route that would allow the Zoom-Zoom brand to keep the roadster light and nimble, while still delivering an extra boost. Neither would be without its challenges, but if overcome, the resulting high-performance model could be sold as a Mazdaspeed model in some markets and as an MPS version in others. And, even if such a performance roadster were to get the go-ahead for production in some markets, there's no guarantee that it will be sold in the United States. Here's hoping. Related Video:

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

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.
