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.

Mazda posts second-quarter loss, but gets a rebound in North America sales

TOKYO — Mazda on Thursday posted a 7.59 billion yen ($73.4 million) operating loss in the three months ended Sept 30 as sales contracted amid the coronavirus pandemic. The loss, calculated by Reuters from the company's half-year result, compares with an 18.9 billion profit in the same quarter last year and a 45.3 billion yen loss in the first three months of the business year, which was its worst in quarter in 11 years. Mazda posted a smaller loss in the second quarter after it benefited from a rebound in sales in North America, its biggest market. Vehicle sales there rose 1% from a year earlier.  Sales in the United States have slipped approximately 1% so far in 2020 as compared to 2019, despite strong sales of the CX-9, CX-5 and new CX-30 crossovers.  Japan's No.5 automaker kept its full-year forecast for an operating loss of 40 billion yen. That is better than the average full-year estimate for a 53.3 billion yen operating loss from 17 analysts polled by Refinitiv. For the full business year the maker of the CX-5 SUV crossover and Mazda3 sedan kept its full-year prediction for global vehicle sales to fall 8.5% to 1.3 million units, the lowest in seven years.

2020 Mazda CX-3 adds active safety features plus Apple CarPlay, Android Auto

The CX-3, Mazda's smallest crossover offering, shrinks its showroom footprint for 2020, as the brand makes room for the newly introduced CX-30 just above it in the lineup. The 2020 CX-3 is cut back from three trim levels to just one, although that single offering is bolstered with additional standard equipment including Apple CarPlay and Android Auto, which come to the CX-3 for the first time. Even more significantly, Mazda is adding as standard a batch of active-safety features that includes forward collision warning with automatic emergency braking and pedestrian detection, lane departure warning, adaptive cruise control with stop-and-go, and automatic high beams—formerly an option package costing $1,100. Blind-spot monitoring and rear cross-traffic alert were already standard and continue. The 2020 CX-3 also gains automatic climate control, a head-up display, rain-sensing wipers and LED exterior lighting. For all that, the 2020 CX-3's prices rise just $250 over the 2019 CX-3 figures. The starting figure for the 2020 Mazda CX-3 Sport is $21,685 with front-wheel drive or $23,085 with all-wheel drive (including $1,045 destination). The other news for the 2020 CX-3 is that the Touring and Grand Touring trims have been dropped. Which means that the features exclusive to those trims, such as leather seating surfaces, a power sunroof, heated seats, a heated steering wheel, and a power driver's seat, are no longer offered. Buyers seeking those niceties perhaps are now expected to step up to the CX-30 — although it's not a big leap, with the CX-30 starting at $22,945.
