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.

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.

Best compact SUVs of 2023 and 2024

Compact SUVs are now the go-to choice for family transportation. Actually, considering how popular they are, they have clearly moved beyond only family duty. With such popularity, though, comes an awful lot of competitors, and it can be difficult to figure out which one might be the best compact SUV for you.  It's important to note that by "compact SUV" we're talking about a specific segment. As we describe in our more comprehensive "Best small SUVs" list, there are also subcompact SUVs that vary widely in size amongst themselves, but are clearly smaller than the SUVs below. Frankly, today's segment of compact SUVs isn't exactly compact — some have more cargo space than vehicles that are considered midsize based on their exterior dimensions. They've all grown considerably over the years. While many lists out there just rattle off every vehicle available in a segment, we thought we'd be a bit more helpful and curate your shopping a bit with the top-recommended choices reviewed by Autoblog. We've included both mainstream and compact luxury SUV choices. Best compact SUVs of 2023 and 2024 2024 Honda CR-V Why it stands out: Best-in-class space; excellent hybrid powertrain; sharp interior style; Honda dependabilityCould be better: No lower-price base trim levels; no sporty or off-road niche models; no plug-in hybrid Read our full 2024 Honda CR-V Review Consider the CR-V the baseline for any compact SUV search, and look extra closely at the superb CR-V Hybrid option. Objectively speaking, it's tough to beat due to its massive cargo capacity, voluminous back seat, strong-yet-efficient engines, well-balanced driving dynamics, competitive pricing and features,  and well-regarded reliability. It's easy to see why it continues to be such a best-seller: for the vast majority of compact SUV buyers, and especially families, it checks every box. That's been the case for many years now, however. The all-new 2023 Honda CR-V changes things up by adding a bit more style and character, particularly in terms of its interior design and how surprisingly enjoyable the Sport and Sport Touring hybrid trim levels are to drive.
