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.

Vice chronicles Okinawa's illegal street racing scene

We all know that street racing is dangerous, and that motorsports are best left on the track or drag strip. However, that doesn't mean that there still isn't some outlaw allure among enthusiasts of racing on public roads. In this video, Vice Japan profiles Eikichi Nagayoshi of Japan's island of Okinawa. He is a used car dealer by day and an illegal racer by night.
Nagayoshi has a deep love for his highly customized Toyota Aristo (better known to us as a first-generation Lexus GS) that he claims produces over 1,000 horsepower and has hit 205 miles per hour. He races his car both on drag strips and in drifting competitions, but says that he often has to ship the car to mainland Japan to compete. In the absence of those opportunities, he sometimes gathers friends and takes the racing to the public roads. While we're not down with street racing, this Vice video is an intriguing personality piece, as well as a look into Japan's fabled underground racing scene.

2014 Toyota 4Runner priced at $32,820*

Toyota has announced pricing on its facelifted 2014 4Runner. The rough-and-tumble SUV will be available in three grades: base SR5, upmarket Limited and off-road-ready Trail. Depending on the trim level, buyers will have the choice of rear-drive or one of two different four-wheel drive systems. The sole engine is Toyota's 4.0-liter, 270-horsepower V6.
Entry-level buyers can get an SR5 for $32,820. That includes 17-inch wheels, fabric seats and Toyota's Entune infotainment system. Adding four-wheel drive bumps the price by $2,920, while the Premium Package (SofTex faux leather seats, navigation, sunroof, auto-dimming mirrors and power passenger seat) adds $1,875. All model prices listed do not include $860 for destination and tax.
The Trail starts at $35,725, while the Trail Premium bumps the price to $38,645, adding the same suite of equipment found on the SR5. While it boasts the same standard equipment as the SR5, the Trail is better suited for going off road. A multi-terrain response system comes standard, as does hill-start assist and Toyota's Crawl Control. For an extra sum, buyers can opt for the Kinetic Dynamic Suspension System, which automatically disconnects the sway bars for better articulation and trail holding.
