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.

Mazda CX-5 getting mild refresh

Mazda has found both critical and commercial success with its CX-5 small crossover, and seems to be endeavoring to keep the momentum up with an upcoming refresh. As you can extrapolate from the obvious lack of the usual camouflage, the company isn't reinventing anything in the very near future of the CX-5, but it does seem as thought some tweaks are in the works.
Lighting elements fore and aft appear to have gone under the knife, with the front grille and rear fascia also seemingly to be slightly revised. The side mirrors now look slicker and slightly more upscale with their integrated turn signals, as well.
In all, expect a look that's a touch fresher, without being a radical departure from the existing visage.

2018 Mazda CX-5 Buying Guide | Specs, safety, expert reviews, and more

Crossovers are all the rage these days, and spunky Mazda devotes half of its six-vehicle portfolio to the segment. The compact CX-5 slots right in the middle of its crossover lineup, size-wise, and outsells all other Mazda vehicles by a country mile, with sales continuing to climb so far in 2018. The CX-5 was the first car to feature Mazda's KODO design language, which has given its vehicles a more premium appearance and made the CX-5 longer-looking and more taut. Now in its second generation, Mazda offers the CX-5 in Sport, Touring and Grand Touring trims, with the option of front- or all-wheel drive configurations. This Autoblog buyer's guide is aimed at helping you to make an educated decision about whether to buy the 2018 Mazda CX-5. We'll summarize safety and reliability ratings, engine specs and horsepower, fuel economy ratings and pricing. We'll also touch on what Autoblog's professional reviewer thinks of the crossover. Is the 2018 Mazda CX-5 safe? Based on its crash tests, the National Highway Traffic Safety Administration gives the 2018 CX-5 a four-star overall rating. It awards five stars for frontal- and side-crash protection, and four of five stars for rollover crashes. The Insurance Institute for Highway Safety further vouches for the 2018 Mazda CX-5, giving the crossover its coveted Top Safety Pick + award — at the time of this writing, the only compact crossover to get this rating, thanks to available adaptive headlights. It also has good ratings for all of its crash-test metrics and headlights, a superior rating for front-crash avoidance, with optional equipment, and an acceptable rating for the ease of use of the child-seat LATCH anchors. We encourage you to visit the NHTSA and IIHS websites to review ratings on the specific vehicle you're researching. Is the 2018 Mazda CX-5 reliable? J.D. Power gives the 2018 Mazda CX-5 an overall score of 75 out of 100, considered average. On its 10-point scale, it rates the vehicle an 8 on overall quality, which is in the average range, and 9 — considered among the best — for overall performance. It rates an 8 for overall depreciation. As is customary, we note that Autoblog has raised concerns about the way J.D. Power weights serious and less-serious reliability issues. You can read more about that here. According to NHTSA, there has been one recall involving 682 models of the 2018 CX-5 because the side curtain airbags may not properly deploy following a side-impact or rollover crash.
