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.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.

Mazda specs new MX-5 Miata with accessories

It's been 26 years since Mazda showcased the original Miata at the Chicago Auto Show, and now it's returned with a conceptual take on the new model, decked out with all the accessories and optional equipment your roadster-loving heart could desire. Or at least some of 'em, anyway. This show car is painted Ceramic Metallic (Zoom Zoom-speak for "white") and spec'd out with a full aero kit (including front air dam, side sills, rear skirt and lip spoiler) all done up in gloss black, 17-inch BBS wheels and Brembo brakes with red calipers. Mazda is also showcasing a carbon-fiber luggage rack for the new MX-5 that weighs less than two pounds and includes and integrated brake light. "The concept parts and accessories we have showcased at the Chicago Auto Show," said Mazda's North American chief Jim O'Sullivan, "were developed to give customers a look at what is possible for the new cars to make them truly one-of-a-kind, adding to that excitement." See them shown off in our high-res gallery of live photos, above.
