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.

2014 Toyota Corolla to bow before LA

We've sort of been wondering when Toyota would finally debut the next-generation Corolla sedan, especially since the current car is getting very, very long in the tooth. We got a glimpse of the new compact's design at this year's Detroit Auto Show in the form of the Furia concept seen above, but we figured we'd see the production car by now.
According to Edmunds, Toyota will be unveiling the new Corolla sometime soon, and it won't wait until the Los Angeles Auto Show in November. Officials from the Japanese automaker did not state a specific location or date for the new car's unveiling, but said that the 2014 Corolla is expected to be on sale before the LA expo later this year and that it will be revealed "somewhere in the US."
Toyota did not divulge any details about the new Corolla, and we're willing to bet that the aggressive lines of the Furia concept will be dulled down quite a bit for the production model. Still, news that the new car is coming sooner rather than later is indeed a good thing.

YouTube's Super Bowl commercial buzz list dominated by automakers [w/videos]

After Sunday's big game, YouTube will be the place to watch every commercial that you missed when you left your seat for an emergency guac refill or, as we say in Cleveland, took the Browns to the Super Bowl. That makes YouTube the nation's water cooler on Monday, and it's got some preliminary stats to share in the lead up to kickoff.
As you know, Super Bowl advertisers, particularly automakers, like to endlessly tease their big budget commercials in the weeks before the game, many times revealing them outright days in advance. Because of this, YouTube can tell us which commercials have been viewed the most so far, and their top five list is all automakers.
Kaley Cuoco appears to have been a good investment for Toyota, as her ad for the RAV4 has garnered the most YouTube views - six million and counting - among Super Bowl commercials so far. Second place goes to Mercedes-Benz, though not its actual Super Bowl commercial, but rather the teaser for it. You know, the one with Kate Upton and the car washing, which is up to 5.6 million views. Third place is Audi's Prom commercial (3.3M views), fourth goes to Volkswagen's slightly controversial Get In, Get Happy ad (3.3M views), and the fifth and final spot is bookended by the teaser video for Kaley Cuoco's commercial (3.2M views). You can watch all five in order below.
