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.

2019 Mazda CX-5 Review and Buying Guide | The driver's choice

The 2019 Mazda CX-5 stands out in an ever-expanding field of similarly sized compact crossovers. There are several good options for shoppers looking to replace the traditional family sedan with something that sits up a little higher and offers some added utility via a reasonably sized open cargo area instead of a closed-off trunk. But if you really enjoy spending time behind the wheel, there isn’t a small crossover that can match the Mazda CX-5Â’s blend of excellent driving dynamics, practicality and affordability. For that reason, weÂ’d suggest that everyone shopping in this segment should take the CX-5 for a test drive. WhatÂ’s new for 2019? The CX-5 gets its first significant update since being completely redesigned for 2017. There are two new engine choices. A 2.5-liter turbocharged four-cylinder is the more powerful option the CX-5 has always needed, while the new 2.2-liter diesel engine is the answer for those who want better fuel economy. Every CX-5 benefits from a retuned suspension setup and MazdaÂ’s G-vectoring Control Plus system, which are intended to improve the 2019 CX-5Â’s handling. A revised infotainment system loses its touchscreen capability but now offers Apple CarPlay and Android Auto capability (it is not, however, the all-new and greatly improved system found in the Mazda3). Also new for 2019 is a top-spec Signature trim level that adds a layer of wood and chrome trim to the interior to go along with attractive brown leather upholstery and a 360-degree camera monitor. A set of 19-inch Dark Silver aluminum wheels and unique badging round out the noteworthy Signature upgrades. WhatÂ’s the CX-5's interior and technology like? The CX-5 boasts a handsome, upscale design with materials to match. The cabin conveys the more premium vibe that Mazda is increasingly shooting for – it also makes a more emotional connection than the typical cardboard box on wheels. Its top two trim levels, Grand Touring Reserve and Signature, boast seats that are heated all around and ventilated up front, covered in high-quality leather with contrast French stitching. There's stitching on the dash too, though it goes through rubbery stuff. The padded and stitched pleather on the doors and center console are a nicer touch, as is the subtle dark wood and alloy trim – especially the air vents that seem to jut out from within the dash.

Mazda Hazumi concept presages next Mazda2

Looks like Mazda's big Geneva Motor Show debut is actually something quite small. Teased here, the Hazumi concept "points the way to the future" for the brand's subcompact offering, the Mazda2. Details are slim as of this writing, but from what we can see in the image above, the Hazumi will use the same Kodo design language found on the Mazda3, Mazda6 and CX-5. We're big fans of this styling direction, so we fully expect the concept to be quite an attractive little number.
Hazumi means "bound" or "spring up" in Japanese, with Mazda saying this nomenclature is "particularly well-suited to a small car that appears to be bursting with energy." In other words, say goodbye to the friendly faced Mazda2 we've enjoyed since it launched in the United States in 2010. Instead, prepare for something decidedly more assertive, hopefully improving upon the already-great driving dynamics of the current subcompact. If we're honest, we can't wait.
Mazda will also use the Geneva show to debut its new small-displacement, 1.5-liter Skyactiv-D diesel engine. The automaker hasn't confirmed that this new fuel-efficient powerplant will be part of the Hazumi concept package, but considering the two are debuting alongside each other, it would seem to make sense. As for whether or not this engine could come stateside when the next Mazda2 launches, we're not holding our breath for that, especially considering the company's current woes with US-spec diesel engines.
