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.

Dodge Durango SRT, Ford F-150 Lightning and why we like physical controls | Autoblog Podcast #678

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by News Editor Joel Stocksdale. They start things off by discussing cars they've been driving, including the 2021 Dodge Durango SRT and the 2021 Toyota Camry Hybrid XSE. Next they discuss the announcement of the Ford F-150 Lightning electric truck, Genesis G70 Shooting Brake and the use of physical controls in cars instead of touchscreens. Finally, they help a reader spend some money.

Recharge Wrap-up: Nissan "religious" about zero-emissions, Tesla crashes at dealership, Formula E on-board video

Nissan is pretty darn serious about being king of the EV industry. Just see what Chief Planning Officer Andy Palmer has to say at the launch of the e-NV200: "When it comes to zero emissions, we're absolutely religious. We'll be the absolute, No. 1 leader in zero emissions. No doubt. That's our positioning." Bold words, to be sure. Toyota, on the other hand, ended its collaboration with Tesla (whom Nissan mustn't forget about in its quest to reign supreme in the EV world) to build the RAV4 EV, and will focus instead on hybrids and testing the waters with hydrogen cars. Says Jim Lentz, CEO of Toyota North America, "I would rather invest my dollars in fuel cell development than in another 2,500 EVs." Read more at Automotive News or Autoweek. To celebrate 25 years of TDI technology, Audi is releasing the A7 Sportback 3.0 TDI Competition special edition in Europe. The Competition uses Audi's biturbocharged, 3.0-liter diesel engine boosted to 326 horsepower, giving the car a 0-62 time of 5.1 seconds. It comes with the S line sport package and is offered in four exterior colors: Daytona Gray, Misano Red, Nardo Gray and Sepang Blue. The interior is black leather, with the option of Misano Red or Agate Gray contrast stitching. The Competition edition will go on sale in August starting at ˆ72,000 (about $97,700). Audi's first Turbocharged Direct Injection engine debuted at the 1989 Frankfurt Motor Show in the Audi 100 2.5 TDI. See the press release down below for more details. There was another Tesla Model S crash recently, this one at the Tesla Store. The driver apparently crashed the freshly purchased car into the Tesla sign before even making it off the lot. According to Reddit user s1lentway, who was at the Tesla Store in Fremont, California when it happened, "We believe this is someone who just got their car. They must have been driving it for less than a minute and lost control, crashing right into the sign missing the showroom glass windows only by a few inches." Wrecked Exotics suggests the driver hit the accelerator instead of the brake pedal. Probably the best comment in the Reddit post: "Edison strikes again."
