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.

2023 Japan Mobility Show Mega Photo Gallery: All the highlights and reveals from Tokyo

The 2023 Japan Mobility Show managed to serve up a surprise heap of exciting and futuristic designs and production reveals. Our staff was on the ground in Tokyo for this year's show, where we captured not just all of the latest automotive trends, but some genuinely weird and fascinating stuff.  Browse: Some Delightful Oddities of the 2023 Japan Mobility Show But on to the cars. This year's show featured introductions from Daihatsu, Honda, Lexus, Mazda, Mitsubishi, Nissan, Subaru, Suzuki and Toyota. Some are weird; some are wild; most are probably destined to change significantly before production or merely fade into the void with the rest of the industry's vaporware, but if even a few of these make it to showrooms, we'll consider it a win. Scroll on down for our live galleries of each of the show's major debuts (and cars we're only now seeing in person for the first time).

Full 2016 Mazda MX-5 Miata pricing released

Take heart, roadster fans. The first 2016 Mazda MX-5 Miatas due for the US are now in production. To go along with that milestone, the Japanese automaker has finally released full pricing for the fourth-generation Miata. As previously revealed, the 2016 Miata in the base Sport trim starts at $24,915 (plus $820 destination), and for that outlay buyers get a 2.0-liter four-cylinder making 155 horsepower and 148 pound-feet of torque that's matched to a six-speed manual. The convertible comes standard with features like LED lighting and a Bluetooth-equipped audio system. For $1,075 more on all models, customers can spec a six-speed automatic gearbox, and keyless entry is another $130 but standard with the auto 'box. One rung up is the Club trim for $28,600, and it improves things with 17-inch wheels, a more aggressive body kit and a seven-inch touchscreen infotainment system. Order the manual trans, and the roadster gets a limited-slip differential, Bilstein dampers and a shock-tower brace. There's also a $3,400 package to make this version of the convertible even sportier with 17-inch BBS wheels, Brembo front brakes, side sill extensions and a rear bumper skirt. Among the regular trims, the top rung is the Grand Touring for $30,065 that adds luxuries like heated, leather seats, automatic climate control, rain-sensing wipers, and adaptive headlights. Mazda's i-Activesense is also standard and includes blind spot monitoring, rear cross-traffic alert and lane-departure warning. Finally, there's the Launch Edition, which is limited to 1,000 units, and it sells for $30,495 (or $31,570 for an automatic). All of them come in an exclusive combo of Soul Red with Sport Tan leather, and buyers get all of the Grand Touring's kit, plus standard keyless entry. The order site for these special roadsters opens on May 5, but hopefuls can pre-register now for a reminder. The first 2016 Miatas should hit dealers in late summer. That should provide some time for top down driving fun before it gets too cold.
