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.

Lexus gets new boss, and he's a designer

A reshuffle in the uppermost ranks of Lexus could see the Japanese luxury brand further energize its recent focus on design. Tokuo Fukuichi, Toyota's global design boss, is the new head of Lexus International.
Fukuichi will retain his role as the overall head of design for Toyota, Lexus and Scion, and will assume his new position at the head of Lexus and on its board on April 1 (no fooling). This is going to be an interesting move for fans of design to watch, as Fukuichi has repeatedly been mentioned as a designer that enjoys pushing the edge of the envelope and experimenting. He is, after all, the man responsible for designing the most awesomely odd minivan of the 1990s, the mid-engined, rear-drive Toyota Previa, and more recently, he signed off on the controversial Lexus LF-NX concept, which is said to presage a new production small crossover.
"Regarding changes in design, no one has 100 percent confidence," Fukuichi told Forbes back in January 2013. "No one can really say with pure certainty that, 'In two years, this will sell well.'" As Akio Toyoda continues to demand more assertive, edgier designs, it's that point of view that should make Fukuichi a valuable addition to Lexus, as it continues to challenge the competition from Germany.

2019 Subaru Forester Sport vs 2019 Toyota RAV4 Adventure: How they compare

The 2019 Toyota RAV4 is not only completely redesigned, but reimagined as well. As we detailed in our first drive review, the new RAV4 ditches the more car-like and uber-utilitarian nature of its predecessor for something that's more SUV-like and characterful. It's a new direction exemplified in the RAV4 Adventure trim, which specifically targets those folks who plan to actually take their compact crossover to the great outdoors. People who will get it dirty, use the extra ground clearance and store things on the roof. You know, the sort of people who would consider the 2019 Subaru Forester. It too is redesigned for 2019, but its transformation is almost unnoticeable compared to the RAV4's. Forester customers were obviously quite happy with the way things were. We got a chance to drive both the 2019 RAV4 and 2019 Forester back-to-back last week both on-road and off-road, so let's take a look at how they compare, including a look at their on-paper specs. 2019 Toyota RAV4 Adventure View 31 Photos Performance and fuel economy The Forester got a new, more powerful 2.5-liter flat-four engine for 2019, and it now comes standard with a continuously variable transmission. It produces 182 horsepower and 176 pound-feet of torque, which is pretty much mid-pack among compact crossovers. Crucially, though, throttle response is so sharp that it makes the Forester actually feel quicker than it is when accelerating from a stop — a sensation enhanced even further by selecting the Sport Sharp mode button on the steering wheel. However, in either mode, the engine's remarkable power reveals itself as the tachometer and speedometer wind toward higher digits. One must also deal with the Forester's CVT. Perhaps some may appreciate the smooth, uninterrupted acceleration that results from a lack of gear changes (nor even simulated ones as in some other company's CVTs), but others may find it unusual and irritating. Subaru's CVT is certainly not our favorite example. By contrast, the 2019 RAV4 is conventional with its 2.5-liter inline-four engine and eight-speed automatic transmission, which behaves just as normally and effectively as one expects. The RAV4 is also considerably more powerful at 203 hp and 184 lb-ft — both compared to the Forester and to the entire segment as well. As a result, its acceleration is stronger (likely a difference of a half-second in 0-60-mph time) even if it may not initially feel like it.
