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.

Toyota turning landfill gas into hybrid vehicles, indirectly

Chamillionaire certainly wasn't referring to the Toyota Avalon or Camry when he rapped about "ridin' dirty" but maybe he'll change his tune soon. That's because some of the future energy sources for the Kentucky factory that makes those two models will come from gas created from the breakdown of solid waste. So the power behind some of the production at Toyota's largest North American factory will indeed be funky. Toyota is working with Waste Services of the Bluegrass to build a network of wells at a nearby landfill in order to collect the gases. Construction of the system starts next month and will be finished by early next year. The upshot is that the system will produce one megawatt of electricity per hour, which is the equivalent to the power used by 800 houses. Last spring, Toyota said it would start producing the Lexus ES at the Kentucky plant after getting almost a $150 million offer from the state. That's because that model is expected to add 50,000 vehicles to the existing production numbers at the plant. And those production numbers are already large, as Toyota makes both the standard and hybrid versions of both the Camry and Avalon there. Mind you, Toyota's not the first to go this route for factory-energy production. In 2011, General Motors' Orion Assembly Plant started getting about 40 percent of its energy for production of models such as the Chevy Sonic and Buick Verano from methane captured from a landfill nearby. The General estimated at the time that the process would cut the company's energy costs by about $1.1 million a year. Check out Toyota's press release about the Kentucky plant and its future landfill gas below. Landfill Gas to Build Cars and a Greener Community Partnership between Toyota and local landfill turns garbage into good March 24, 2014 GEORGETOWN, Ky. (MARCH, 24 2014) – Can a car company be a vehicle for change? Toyota thinks so. The Kentucky plant that manufactures some of the greenest cars on the road, including two hybrid models, will soon be powered in part by green electricity. Toyota Motor Manufacturing, Kentucky, Inc. has teamed up with Waste Services of the Bluegrass to generate power from local landfill waste, marking the region's first business to business landfill gas to energy initiative. Toyota estimates the locally-generated landfill gas will supply enough power each year for the production of 10,000 vehicles. How it Works As solid waste naturally breaks down in a landfill, it creates gas.

Cheap, honest transportation | 2017 Toyota Yaris iA

In The Love Bug, the main character (aside from Herbie) is a down-on-his-luck racing driver named Jim Douglas. Early on, he steps into an exotic car show room, and when the dealer asks him kind of car he's looking for, Douglas replies, "What do you have in the way of cheap, honest transportation?" The dealer quickly snatches his fancy liquor back from Douglas and soon after Herbie shows up from the back of the showroom. But if this happened today, you could easily replace the classic Beetle with a 2017 Toyota Yaris iA. The poor thing isn't nearly as endearing to look at as a classic Bug, as a result of the rather unattractive nose, and it's now using a second pseudonym (first Scion iA, then Toyota Yaris iA) to hide its Mazda heritage. However, everything else about it nails the description of cheap, honest transportation. And for that reason, it's a lovely little car. Let's start with honesty, and it begins from the minute you start equipping the car – the iA is a "what you see is what you get" proposition. You see, the iA moniker isn't the only holdover from the Scion era. The Toyota Yaris iA retains its "monospec" configuration, which means it comes with only one option: the transmission. Customers can choose from either a 6-speed manual like our test car, or a 6-speed automatic which costs $1,100. Everything else is standard, and "everything" includes some choice features. You get alloy wheels, air conditioning, cruise control, USB and Bluetooth integration, a rear-view camera, tilt and telescoping steering wheel with audio controls, and keyless entry with push-button start. Technically there are a number of dealer-installed accessories too, including your typical fare of mudguards, rear spoiler, cargo organizers, and such. However, none of them are really necessary, with one exception. For some odd reason, the Yaris iA does not come with a center armrest. It's a $195 accessory, and frankly it should be a standard feature because it's so useful. If you hadn't guessed, ours wasn't equipped with it. Everywhere else the iA is a thoroughly pleasant car, if not as sporty as the old Mazda2. The little 1.5-liter four-cylinder under the hood isn't particularly potent with 106 horsepower and 103 lb-ft of torque. But with a Miata-like 2,385-pound curb weight and our car's manual transmission, it manages to feel fairly sprightly, and never has any trouble dicing it up with traffic. That transmission is pretty decent, too.
