Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.

Fiat version of Mazda MX-5 Miata to be called 124 Spider

Fiat has a definite use for its recent US trademark on the 124 Spider name, and it's something that should make many performance fans quite happy. FCA CEO Sergio Marchionne confirmed to Auto Express that the Italian brand's future roadster would bear the classic name. Auto Express reportedly asked Marchionne directly about the convertible at the 2015 Geneva Motor Show. The CEO said: "Do we want to do it now?" After another executive verified the name, Marchionne responded: "There you go – a world class premiere right in this room!" Autoblog reached out to Fiat Brand communications boss in the US Ariel Gavilan for more information, and he verified the story. Gavilan said that brand head Olivier Francois confirmed the 124 Spider name to international media during a briefing in Geneva. FCA isn't going quite so far as officially confirming that the 124 Spider shares a platform with the latest Mazda MX-5 Miata, but that's almost a certainty. The two automakers jointly developed the chassis, and the original plan was for it to underpin an Alfa Romeo. However, Marchionne didn't want an Alfa assembled outside of Italy. Fiat even hinted at this possible change as far back as the corporation's five-year plan last summer. Insiders tell Auto Express that the 124 Spider reportedly carries retro-inspired style, and hopefully, that means the roadster evokes the look of the original 124 Sport Spider (pictured above) by Pininfarina. Fiat allegedly is also aiming for a weight less than 2,205 pounds, and the engine range is likely comprised of versions of the brand's 1.4-liter turbo. The mill already pumps out 160 horsepower and 183 pound-feet of torque in the Fiat 500 Abarth in the US. According to Auto Express, Fiat and Mazda have an agreement to launch the Miata in 2015 and the 124 Spider in 2016. A hotter Abarth version could come along eventually, too. Related Video:

J.D. Power dependability survey is out, but you shouldn't depend on it

J.D. Power has just released its latest automotive dependability survey, which of course has usual suspects Buick and Lexus ranking high. Those are safe and solid findings, surely. But when you look a little closer, there are curiosities. Our Consumer Editor, Jeremy Korzeniewski, offered an explanation a couple of years back for why this survey should be viewed with a degree of skepticism, and his take is worth a re-read. What jumped out at Jeremy were the relatively low spots assigned to Mazda, Subaru and Scion among the ranking of makes. Back in 2016 when he wrote his piece, they were ranked 21st, 23rd and 24th respectively. In this year's survey, Mazda ranks 15th and Subaru 26th, both below the industry average of 142 reported problems per 100 vehicles. (And Scion, of course, is in car-brand heaven.) Now, part of what is going on here is surely the fact that all automotive brands are producing dependable vehicles compared with years gone by, so the degree of variance between the best and worst on the list is not as great as it once was. "For the most part, automotive manufacturers continue to meet consumers' vehicle dependability expectations," Dave Sargent, a J.D. Power vice president, said in a statement. "A 9 percent improvement is extremely impressive, and vehicle dependability is, without question, at its best level ever." That said, when a brand like Subaru, regarded by many as mechanically bulletproof, ranks 26th, it leaves people who know cars scratching their heads. Something there does not compute. The problem, as Jeremy pointed out, is one of methodology: When he wrote his piece, there was no weighting assigned to the problems reported in the survey. And that still appears to be the case. Therefore, a problem with an infotainment system or a loose piece of trim is deemed as serious as a blown engine or leaky transmission. (And yes, infotainment is still the biggest problem across the board.) Jeremy's point: If the categories of problems were weighted, you'd see a different picture. When you look at the Consumer Reports brand rankings (subscription required), you get a very different picture. in CR's rankings, Subaru is No. 6 among brands, which, well, sounds a lot more like it. CR singles out the redesigned 2017 Impreza as a car with some new-model problems. (The BRZ had the fewest.) The two surveys jibe a little more closely when it comes to Mazda, which CR ranks 12th, a drop of six places from previous-year rankings.
