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.

Buy a Fiat 124 Spider Abarth, get a free day of driving school

We know the Mazda MX-5 Miata and the Fiat 124 Spider are basically the same car underneath. As we pointed out in our first drive of the 124 Spider, the two cater to different drivers, so it can be tough to choose a favorite. FCA has made deciding between the two sports cars a little harder, as it will offer Abarth owners a free day of high-performance driving instruction with their cars. Anyone buying or leasing a new Fiat 124 Spider Abarth or a Fiat 500 Abarth will get a free, one-day class at the Bob Bondurant School of High Performance Driving in Phoenix. Bundling driving school with brand-new performance cars isn't unheard of – Dodge and Bondurant recently announced a similar program for the Viper – but it is quite rare for vehicles priced below $30,000. The free session will include instructor-led skid, autocross, slalom, and team rally cross activities, in addition to hot laps. While the one-day course is included for free, travel, food, and hotel expenses aren't covered. Fiat-less people can also join in on the fun buy purchasing the Abarth experience separately. Bondurant one-day classes cost at least a grand, which makes the Fiat price of $0 a good deal as long as you can get yourself there relatively cheaply. But is this enough for drivers to choose the 124 Spider Abarth over an MX-5 Club? This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Car Club USA: Miatas at Mazda Raceway Laguna Seca

The Mazda MX-5 Miata is a very popular car for weekend warriors looking for the thrill of automotive racing in an affordable package. These iconic, rear-wheel-drive roadsters are lauded by enthusiasts for their driving dynamics, reasonable price, and plethora of available parts. That's why the annual Miatas at Mazda Raceway Laguna Seca track event draws such a diverse cross section of drivers from allover the country. But, still, some types of drivers are more well-represented than others. "I usually am the only female signed up for the high-performance driving," said Carolyn Kulaja of Gila Monster Racing. "The car doesn't care the gender of the person driving." For Carolyn, racing Miatas is a passion that developed later in life, but she's not slowing down anytime soon. "My first racecar was car number 57, which was my age when I started racing," said Carolyn. "The 88 I decided was going to be my age when I quit racing." Young competitor Kyle Koh of Infotech Motorsports has his own reasons for racing. "Driving has changed my life in a major way," said Kyle. "It took me out of a depression." Kyle's first competitive fire was directed toward football, but after breaking his back during his sophomore year of high school, he had to find another outlet. "Kyle came to me one day and he decided that he wanted a project car," explained Kyle's father and racing partner Larry Koh. "Because the Miata community is so friendly to begin with, it becomes a big family." How will Carolyn and Kyle fare through Laguna Seca's infamous corkscrew? Find out on this episode of Car Club USA. Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.
