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.

400-hp Toyota Hybrid-R Concept gets second teaser

Toyota has released a second teaser of its Hybrid-R Concept, along with an estimation of the show car's power output. Using technology that's "similar to that used by Toyota Racing's TS030 Hybrid race car," the concept is expected to deliver over 400 horsepower.
The press release also mentions that the new concept is based on a current production model. While it's difficult to tell from the sole teaser image of the car's body, rumors are flying that it's related to the Yaris. If that's the case, though, it's difficult to know what to make of this concept. The teaser image is quite dark, but we played around with the exposure and came up with an image that reveals more details about the new concept. Take a look at the related gallery, below, to see the high-exposure image. We'll find out for certain what the Hybrid-R is in a few weeks at the Frankfurt Motor Show. Let us know what you think Toyota's newest concept is in the comments.

Recharge Wrap-up: Toyota i-Road and COMS in France, Tesla tours Northeast, EV attitudes in UK

Toyota's i-ROAD and COMS teeny, tiny, city EVs are joining the Citelib carsharing fleet in Grenoble, France. The ultra-compact EVs, which will become available in October, are meant to supplement the Grenoble metropolitan area's existing public transit infrastructure, which includes trams, buses and trains. Toyota's i-ROAD and COMS will be connected to the transit systems IT infrastructure, allowing users to visualize their route on their smartphone or computer, and reserve and pay for their car before they get dropped off near the charging station (or the other way around). Then, the user finishes (or begins) their trip with one of the EVs. Surveys show that use of public transport is increasing in Europe, but most users still have to walk 15 minutes or so to reach their destination. Adding the i-ROAD and COMS carsharing service to their commute makes the trip into the city center quicker and more flexible, while keeping the air clean. See more below. Toyota is providing 70 vehicles to the Citelib program as part of a three-year test, while French energy company EDF is contributing 30 charging stations to the project. The i-ROAD is a three-wheeled EV that seats two people, and it features Active Lean technology for stability and comfort in the corners. Its footprint is about one-fourth that of a regular car. The four-wheeled COMS EV seats one, but also features a small storage compartment in the rear. The Tesla Model S is going on tour throughout the Northeastern US to give test drives to the public. Beginning July 4 in Montauk, NY, and ending August 30 in Vergennes, VT, people will get the chance to take a 15-minute spin in what many consider to be the best electric car available as part of Tesla's Fully Charged tour. If you live in New York, New Jersey, Massachusetts, Maine, Connecticut, New Hampshire or Vermont, the Model S may be coming to a town near you (check the schedule here) and you'll get the chance to drive the car with a product specialist in the passenger seat to answer your questions. You can even bring up to three guests in the back seat. So if you live in one of the states where Tesla can't sell cars or doesn't have a store, this is your chance to get to know the vehicle and decide if you want to buy one. Or you can just see what it feels like to silently go from 0-60 in 4.2 seconds (hint: it's pretty cool). A UK Survey shows five percent of people there are considering buying an electric vehicle.
