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.

2016 Mazda MX-5 Miata Club long-term wrap-up | Farewell, fun friend

About one year ago, we took delivery of a 2016 Mazda MX-5 Miata. We made sure we got the sportiest version we could, the Club model (which includes Bilstein shocks, a limited-slip differential and a front shock tower brace) with optional BBS wheels and Brembo brakes. We also sprung for the appearance package to give our cute little roadster a modicum of aggression. It was a tad pricey at $32,835, but we enjoyed every minute of it. Well, almost every minute of it. It's not a perfect car, as it's loud and stiff on the highway, and we ran into an issue in which the top had to be replaced (under warranty). But minor grievances aside, just about everyone who drove the little roadster came back with a smile, especially when we took it to a racetrack. Below are final thoughts on the car from our editors. Senior Green Editor John Beltz Snyder: This car is about as car as any car gets. It's so car! That is to say, it's pure in its mission and in its effective execution as a driver's plaything. Its crisp steering, snickety six-speed manual gearbox, and rev-happy engine create the wonderful sensation that you're driving faster than the speedometer reads. Normal speeds never felt so heroic. The view out the front is fantastic, too, and the curves of the hood are nothing short of inspiring as they frame the road ahead. I don't care that it's noisy, jarring, and ergonomically weird. Old and British in spirit, it offers a level of engagement that's hard to find in a new car, especially for under $30,000. Anyone who has a Miata in their stable isn't lucky. They're smart. Senior Editor Alex Kierstein: I'm a bit embarrassed to think back to my first impressions about driving the MX-5 now that I've had so much seat time in this one. While I loved the idea of it as a throwback to the original NA Miata from the moment it was revealed, I was a bit turned off by how civilized it was. And how quick it was. No longer a momentum car, the new MX-5 seemed more forgiving of bad gear selection or a bad corner entry. I felt like something had been removed, a ragged edge, some everyday engagement. Well, a year on, and my feelings have changed. If you stop comparing it directly to the (slow, weedy, rattly, uncomfortable) first- and second-generation cars, it's a brilliant little roadster. I miss the raw edge less and enjoy the livability more — the raw edge was really just a lack of civility. A flaw that forced you to engage with the thing every moment.

2014 Mazda6 earns Popular Mechanics' 'Car of the Year'

Ring one up for Mazda. The Japanese brand's midsize offering, the Mazda6, has been named Popular Mechanics' Car of the Year. The 6 received a comprehensive reworking for the 2014 model year that saw it adopt sleek, sexy sheet metal; a clean, logical interior; and powertrain technologies that allow it to net some of the best fuel economy available in a gas-powered, non-hybrid sedan.
Popular Mechanics praised the 6's Skyactiv 2.5-liter, 184-horsepower engine, as well as its agility and responsiveness during testing. It also remarked on the functional, but well designed cabin, and the degree of available technology.
"The Mazda6 really impressed us with how well it delivers so many things modern car owners want: great mileage, fun road-handling, upscale features and looks - and remarkable value," said Jim Meigs, Editor-in-Chief of Popular Mechanics.
