Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Mazda to use rotary engine as a range-extender with its first electric vehicle

There's more news from Mazda at the Tokyo Motor Show, where the brand made a big splash, including new developments in its never-ending rotary engine saga. First, Mazda execs confirmed that the Japanese automaker will bring back the rotary engine as a range-extender and battery juicer for its first electric vehicle in 2019. But secondly, the company won't have a rotary-powered successor to its RX-7 and RX-8 sportscars in time for the company's centennial anniversary in 2020. Autoblog previously confirmed that Mazda is planning to have an EV in 2019 that will be available in both pure electric and range-extending versions. Now, the Australian website Motoring reports that the global EV will feature a powertrain similar to the experimental Japan-only Mazda2 (Demio) EV, which used a single-rotor engine as a generator to power the battery pack and increase its driving range. The publication says Mazda plans to release a series of plug-in hybrids based on existing models around 2020, then a pure electric car co-developed with Toyota and Denso in 2021 as part of the EV Common Architecture Spirit Company joint venture. A Mazda spokesman tells Autoblog the company couldn't confirm any details about future products. Meanwhile, enthusiasts shouldn't wait for a rotary-based production version of Mazda's RX-Vision concept from 2015. Motoring cites two executives who explain that the company simply lacks the capital necessary to invest in developing the new model in time for its 2020 centennial. Mazda debuted its rotary engine 50 years ago in the Cosmo Sport in part as a way to stand out from its larger Japanese competitors. The engine, which uses a spinning three-tipped rotor in place of pistons, is smaller and lighter than conventional piston engines, with a greater power-to-weight ratio and quieter, smoother operation. But it delivers less fuel economy and higher emissions — two weaknesses that could be improved via a stop-start system Mazda has developed, based on a pair of U.S. patents. The company has also been hard at work developing its next-generation Skyactiv-X engine, which uses highly precise combustion ignition technology to deliver significant gains in fuel economy and power.Related Video:

Lexus tops Consumer Reports reliability rankings, unseating Mazda

Lexus is back on top of Consumer Reports' annual reliability rankings. Toyota Motor Corp's luxury division dethrones last year's winner, upstart Mazda, to second place, while the Toyota brand itself rounds out the podium in third place. In general, while Asian brands topped the list, Europeans ranked second, and domestics brought up the rear.  Lexus' high marks stem from the Land Cruiser Prado-based GX SUV, which got a perfect score of 100. Mazda's second place finish was the result of strong showings by the Miata, CX-9, CX-5, and CX-30, but dragged down by the Mazda 3's mid-pack score. Likewise, nearly all of Toyota's lineup, from Prius to Avalon, all had very high marks, but the RAV4 and Corolla Hatchback brought down the class average. Like last year, the only American brand to break into the top ten was Buick, which ranked 5th thanks to good scores for the Envision and Encore (though the Enclave ranked sub-par). Eight of the top 10 brands were Japanese, with Infiniti in 4th, and Honda, Subaru, Acura and Nissan following Buick in that order. Mini, in 10th place, was the only European brand in the top 10. The bottom spots went to Jeep, Tesla, and once again Lincoln in dead last. While all Lincolns received poor scores, the Aviator was notable for getting only 3 points out of 100. Similarly, last year's lowest-scoring vehicle was the Ford Explorer, with which the Aviator shares a platform. It wasn't all gloom from the domestics, however. The Chevrolet Trailblazer tied the Lexus GX with a perfect score, but overall Chevy brand ranked 14th, pulled down by the Corvette, Silverado 1500 and Tahoe. The Tahoe tied with the GMC Yukon with the lowest scores this year, just 2 points each. Both the Silverado 2500HD and the nearly identical GMC Sierra 2500HD were among to top scoring American vehicles, along with the Ford Bronco Sport, Mustang Mach E, Ranger and Chrysler 300. Consumer Reports also points out that the oft-said line that electric vehicles are less prone to problems due to fewer moving parts isn't necessarily true. The Audi E-Tron and Tesla Model X each got a score of 5, the lowest of their respective brands, due to more and more technology being crammed into these higher-priced EVs.
