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.

2018 Nissan Kicks vs other tiny crossovers: How they compare on paper

Update: As we now have now driven the 2018 Nissan Kicks and have all the specs and figures available, we thought it was time to update this comparison post. The data chart has been updated with final Kicks information as well as changes to competitors made for 2019. Anyone else have "Pumped Up Kicks" by Foster the People stuck in their heads? Well, you do now. I couldn't be the only one. Anyway, the 2018 Nissan Kicks is a thing. It replaces the Nissan Juke, which Mr. Stocksdale thought was a bad idea and Mr. Myself thought was a smart idea. Nevertheless, neither of us were especially pumped up by the Kicks. However, the majority of car buyers are all about SUVs, and this littlest segment of them has been multiplying like Tribbles in the past few years. The Juke was one of the first of these subcompact crossovers, but it was probably too oddball for a mainstream audience (not to mention inefficient) and never really caught on. Newer competitors certainly didn't help. Well, to see how the Kicks compares to those very competitors, lets fire up the Autoblog Comparo Generator 3000 (TM). Specifically, we'll be looking at those subcompact crossovers with similarly small dimensions, especially low prices and/or a disinclination to offering all-wheel drive. We're talking about the Nissan Kicks vs the Toyota C-HR, Hyundai Kona, Kia Soul, Honda HR-V and Jeep Renegade. Now, if you're interested in literally the exact opposite SUV segment, check out our recent Mercedes G-Class comparo. Otherwise, on to the spreadsheet: Dimensions and passenger space In terms of exterior dimensions, the new Kicks is right smack in the middle of the segment. It's virtually the same as the Honda HR-V, yet manages to eek out a few extra cubic feet of cargo space behind its raised back seat. The Honda and its "Magic Seat" still beats it in terms of maximum capacity, but it sure is close. The Kia Soul has the biggest maximum number, but that's largely the result of being a box. Its small behind-the-back-seat cargo number is likely a better indicator of how much you'll be dealing with on a day-to-day basis. And in that day-to-day way, the Kicks is excellent. Backseat legroom seems to be a Kicks downside, as all but the C-HR surpass it. (Seriously, it's almost impressive how large the C-HR is on the outside but cramped inside.) However, the Kicks' tall greenhouse not only allows for ample headroom, but seats that are mounted high off the ground.

Tech of the Year special, plus we drive the hydrogen Mirai and more | Autoblog Podcast #809

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick and Road Test Editor Zac Palmer. They kick the discussion off by talking about what they've been driving as of late, including the Toyota Mirai, Dodge Hornet, Alfa Romeo Tonale and a trio of subcompact SUVs. After that, they dive into a discussion about the 2023 Autoblog Technology of the Year award winner, which is Mercedes-Benz's Dolby Atmos Spatial Audio. Once they wrap up that segment, we get to hear the crew's latest Cybertruck takes from before the big reveal. Finally, the show wraps up with a fun Spend My Money segment.
