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.

Recharge Wrap-up: Minnesota first to require biodiesel, maglev in Israel, Toyota FCV in Aspen

A new Minnesota law that requires biodiesel blends goes into effect in just a few days, says KELO. Diesel drivers in Minnesota will be pumping soybeans into their tank beginning July 1. Every year, diesel will be sold as a B10 blend (ten percent biofuel) from April through August, and will scale back to a cold-hardy B5 blend from September through March. The biofuel largely comes from soybean crops grown within Minnesota, and the biodiesel industry pumps more than $900 million into the state economy every year. According to the National Biodiesel Board, using the B10 and B5 blends will reduce greenhouse gas emissions by 1,342,000,000 pounds every year. Minnesota is the first state to require diesel to be sold as a biofuel blend. In Japan, Isuzu Motors and Japanese biotech venture Euglena are teaming up to create biodiesel using algae, according to Bloomberg Businessweek. The goal is to create a new type of fuel that doesn't need to be mixed with light oil to be used in engines. "As long as we use light oil for diesel engines, emissions of carbon dioxide are inevitable," says Isuzu president Susumu Hosoi. Euglena has also been using algae to develop jet fuel with airline operator ANA Holdings. Isuzu and Euglena hope to have the new biodiesel developed by 2018. Aerial maglev transportation is coming to the campus of a defense contractor in Tel Aviv, Israel, Wired reports. The SkyTran personal rapid transit system uses small pods on an elevated magnetic track to move people from place to place. The pilot program will see SkyTran come to the corporate campus of Israel Aerospace Industries as soon as next year. The pods are hailed by phone, and carry passengers along the magnetic rail system at speeds of up to 44 miles per hour. The passive magnetic system levitates the pod attachment a centimeter above the rails, while a burst of electricity propels the pod forward. If the test at the campus goes well, SkyTran could spread to Tel Aviv at large, moving up to 12,000 people per track per hour with top speeds of 150 mph. The pre-production prototype of the Toyota FCV will make its North American debut at the 2014 Aspen Ideas Festival on Friday, June 27. The hydrogen car's finished exterior was revealed in Japan on Wednesday along with its nearly $70,000 price tag. It will go on sale in Japan by April of next year, and will come to Europe and California in the summer of 2015.

2020 Ford Escape plug-in vs. Toyota RAV4 Prime, Mitsubishi Outlander PHEV: How they compare on paper

This year is when the entry-level plug-in crossover market really starts to heat up. Both Ford and Toyota have new models in the 2020 Ford Escape and the 2021 Toyota RAV4 Prime. They join the segment veteran Mitsubishi Outlander PHEV, which has been available in the U.S. since the 2018 model year. And of course that means it's time to look at how the numbers add up while we wait for our chance to drive the new competitors. You can find a chart with all the details immediately below, followed by more detailed analysis. Powertrain One of the key factors for any hybrid, particularly plug-in models, is how little fuel they use. Overall, the Ford Escape is the winner with 100 mpg-e, the fuel economy equivalency for the vehicle when assessing it with a full battery. The Toyota is close behind with 94 mpg-e. We're expecting the Escape to also be a bit more efficient when running only on gas, as it reportedly gets 41 mpg. The RAV4 will likely get 40 mpg, or possibly slightly less, since the non-plug-in RAV4 Hybrid achieves 40 mpg combined. Running solely on electric power, though, the RAV4 edges out the Escape with 42 miles of range versus 37. Behind both of them is the Mitsubishi with just 22 miles of range, 25 mpg on gasoline only, and 74 mpg-e with a full battery. One unique feature the Mitsubishi claims is DC fast charging capability, meaning 80% of its electric range can be restored in just 25 minutes, possibly allowing for more electric use depending on where you're driving it. While fuel economy is a priority for hybrids, customers won't want to compromise on other features. The Toyota is easily the least compromising, as it returns impressive range and efficiency while also providing a whopping 302 horsepower and all-wheel drive. The Mitsubishi also has all-wheel drive, but a comparatively paltry 190 horsepower. The Ford produces slightly more power at 200, but is front-wheel-drive only. While low in comparison to the RAV4 Prime, the Mitsubishi and Ford have very competitive output to many comparably-sized conventional crossovers with base engines, such as the Honda CR-V, Chevy Equinox and others. Size and space Naturally one of the reasons for buying a crossover is for its practical shape for comfortable hauling of people and stuff. In this regard, all three crossovers are very close. The Escape wins out with legroom, the Toyota with shoulder room. Headroom is split between the Toyota and Mitsubishi.
