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.

Stellantis and Toyota expand partnership with large commercial van

Stellantis said on Monday it would expand its partnership with Toyota Motor Europe (TME) with a new large commercial van, including an electric version. Stellantis will supply TME, a unit of Japan's Toyota Motor Corp, with the new vehicle for sale in Europe under the Toyota brand, it said. The van will be produced at Stellantis plants in Gliwice, Poland, and Atessa, Italy. "Planned for mid-2024, the new large-size commercial van marks TME's first entry into the large-size commercial vehicle segment," Stellantis added in a statement. The deal widens the partnership between the two companies and allows a better optimization of Stellantis' Atessa plant, which currently makes large vans sold under the Peugeot, Citroen and Fiat marques. "It represents an important addition and completes our light commercial line-up for Toyota's European customers," Stellantis said. Paris-listed shares in Stellantis were up 1.6% by 0941 GMT. Carmakers have increasingly been agreeing cross-manufacturing deals to reduce costs in vans, which due to a boom in parcel delivery are seeing large demand — and where electric vehicle versions are also seeing rising sales to carry out "last-mile" deliveries in city centers.

2014 Toyota Tundra to debut at Chicago Auto Show

The fullsize pickup market is dominated by trucks from Ford, General Motors and Ram, but this segment could get some hefty competition in coming years. We've already reported that Nissan is planning a redesign of its Titan truck for 2015, and now Toyota has announced that it will be revealing the 2014 Tundra next month at the Chicago Auto Show.
In the brief press release posted below, Toyota says that the 2014 Tundra will be "redesigned," but it's unclear as to whether this means we'll be seeing an all-new truck or just an extensive refresh. The current Tundra design has been around since 2007 and sales are hardly worrisome to the Big Three, so a new design would be a logical guess.
In any case, we only have to wait a couple more weeks for the new Tundra to debut on February 7, and we'll be on hand to bring you plenty of live coverage from the show.
