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.

Editors' Picks March 2021 | Ford Mustang Mach-E, Polestar 2, Land Rover Defender and more

The month of March was unofficial minivan month here at Autoblog. We drove all of them but the Kia Carnival, but don’t worry, you wonÂ’t have to wait much longer to read that review. Among all the family-toting machines, we drove some more exciting vehicles including the Land Rover Defender and a pair of up-and-coming EVs. It was a month of excellent cars, meaning that this monthÂ’s litter of EditorsÂ’ Picks is stacked. In case you missed FebruaryÂ’s picks, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary or stand out in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in March that earned the honor of being an EditorsÂ’ Pick. 2021 Ford Bronco Sport 2021 Ford Bronco Sport First Edition View 32 Photos Quick take: Ford's baby Bronco is an authentic foil to the big Bronco 2-Door and 4-Door. It brings rugged styling, better-than-average off-road capability and thoughtful utility features to a generic segment of cars. Score: 8 What it competes with: Jeep Compass, Jeep Cherokee, Mazda CX-30, Subaru Crosstrek, Kia Seltos, Chevrolet Trailblazer Pros: Stellar design, excellent off-road, clever interior details throughout Cons: Pricier than most, average transmission, underwhelming interior quality and ambiance in lowest trims From the editors: Road Test Editor Zac Palmer — “I genuinely enjoy driving this cute crossover. It feels like a mini truck on the road, and Ford admirably translated the design from its big Bronco over to this Escape-based crossover. News Editor Joel Stocksdale — "The Bronco Sport isn't perfect, the transmission could use some work, and it's a little bumpy, but it's a characterful little thing with loads of style, great visibility and space, and impressive capabilities on and off road in the powerful Badlands form." In-depth analysis: 2021 Ford Bronco Sport Review | Bronco for the masses   2021 Land Rover Defender 2021 Land Rover Defender 110 View 64 Photos Quick take: The Land Rover Defender provides everything you'd hope for in a modern Land Rover: superlative off-road capability, surprisingly plush on-road demeanor, abundant interior space and abundant character. The base four-cylinder is likely all you'll need and lower trim levels provide more than enough equipment.
