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 expanding Aichi's test EV infrastructure in Japan

OK, now we're really confused. In the US, Toyota has been telling anyone who cares to listen that the future of advanced-powertrain technology is hydrogen fuel-cell vehicles, not electric ones. In China, a Toyota joint venture is looking at EVs. Over in Japan? They've just decided to pony up a little more for testing electric-vehicle technology. Maybe something's lost in translation. Toyota has been running an electric-vehicle charging station trial project in Japan's Aichi Prefecture during the past couple of years and is now ready to expand that program, adding 43 new charging stations to the 104 already present. Many of the EVSEs are in municipal-owned properties or in mountainous areas (where EV batteries drain the fastest). Toyota's expanded program started running in Kariya City, Toyota City, Toyohashi City and Nagakute City this month, and testing will extend until the end of next March. There's more in Toyota's press release below. Toyota's electric-vehicle presence is limited here in the US, as the low-production RAV4 crossover is the only model sold here. Toyota executive Craig Scott was recently quoted as saying that the company questions whether there is sufficient demand in the US for pure electric vehicles. With that in mind, Toyota will debut its hydrogen fuel cell model in the US in 2015. Toyota to Test Expansion of EV and PHV Charging Infrastructure in Japan Toyota City, Japan, October 31, 2014-Toyota Motor Corporation announces that it will be testing electric vehicle charging infrastructure in Aichi Prefecture from November 1 until March 15, 2015. The tests will involve standard chargers for use with vehicles such as plug-in hybrid vehicles (PHVs) and electric vehicles (EVs). The tests will be conducted jointly with four municipalities (Kariya City, Toyota City, Toyohashi City, and Nagakute City) and two companies (Toyota Industries Corporation and UNY Co., Ltd.), all of which are located in Aichi Prefecture. Toyota conducted similar tests in FY2012 and FY20131. In addition to targeting commercial, tourist, and accommodation facilities as in past tests, this year's tests will also involve cultural and social service facilities (including some in hilly and mountainous areas). Multiple chargers will be installed at certain commercial facilities where charger use was heavy in last year's tests. The aim will be to ascertain the optimal number and location of charging stations and their ease of use.

Mazda2 refreshed for 2020 with new style and tech

The North American market Toyota Yaris is a badge engineered version of the Mazda 2. Now, the Mazda underneath the Toyota badging has received some updates in its home market of Japan, and it will be interesting to see if or when the U.S. counterpart will be refreshed with any of these updates. The 2020 Mazda 2, now indeed called "Mazda 2" instead of the older Demio name on the Japanese market, has received new front end styling to bring it in line with bigger Mazda models. The grille and bumper are new, as are the headlights with adaptive LED technology and LED daytime running lights. Apparently the headlights are constructed out of 20 individually controlled LED blocks to optimize light output and direction, which sounds awfully interesting for this class of vehicle. The front end design, just like the new 16-inch alloy wheels, is Mazda-specific and the Yarisized version is unlikely to benefit from them, especially since the headlights are also different on the Toyota. Cabin materials have also been updated, and the driver’s seat is available with six-way power adjustability for 2020. The MZD Connect infotainment has Apple Carplay and Android Auto support, like the Yaris setup. In addition, cabin comfort is said to have been improved with better soundproofing, which is sometimes sorely needed in this class of cars. Safety and convenience features include adaptive cruise control, which is impressive on a city car, and the Mazda 2 also has the G-Vectoring Control Plus system for high-speed stability. Both the diesel and gasoline versions will get Mazda's i-Eloop brake energy regeneration system. The Japanese market also gets an all-wheel-drive version, which is surely a hoot despite only being available with the automatic transmission. CarAdvice says the Australian market will receive the redesigned Mazda 2 early next year, which is probably in line with the rest of the global market that gets it as a Mazda instead of a Toyota; Mazda says Japan market pre-orders have started today and official sales will begin on September 12th. It pays to remember that the base car dates back to 2014, and that the 2020 refresh is a facelift instead of a ground-up redesign. Assuming the usually expected shelf-life for the facelifted edition, the 2 will have racked up respectable mileage from the “DJ” generation bodyshell.
