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.

2021 Mazda3 to gain a turbocharged engine, finally, probably

Buckle up, Mazda fans. The Mazda3 turbo might really be happening, says a report from Jalopnik. Some details from Mazda’s dealership extranet system observed by Jalopnik suggest weÂ’ll see a 2021 Mazda3 turbo in both sedan and hatchback form. We donÂ’t have eyes on the documents ourselves, but the report says both the sedan and hatchback versions will be all-wheel-drive only with no option for front-wheel drive. In addition to that, it looks like the turbo models will be exclusively automatic, as theyÂ’re both only listed as “6A” in MazdaÂ’s system. Sorry to break the hearts of those who were hoping for a manual turbo. The hatchback manual with the naturally aspirated 2.5-liter from the modelÂ’s first two years appears to be sticking around for a third, in case you were worried. There is one minor mystery that's a possible glimmer of hope for someone wanting more performance, though. The report says that a “MAZDA3 HB PP TURBO” is listed in the docs. Our hearts are yearning for the PP to stand for Performance Package, but it probably stands for “Premium Package.” ThatÂ’s the name of MazdaÂ’s highest trim Mazda3 right now, and itÂ’d make sense to offer the turbo engine on the upmarket model. The last we heard on this front was from a report published over a year ago. It suggested MazdaÂ’s 2.5-liter turbocharged four-cylinder as a possible drop-in. That motor makes 250 horsepower and 310 pound-feet of torque on premium fuel and would be a big upgrade to the 186 horsepower and 186 pound-feet of torque made by the naturally aspirated 2.5-liter under the hood now. Without a manual, the obvious transmission would be MazdaÂ’s traditional six-speed automatic. ItÂ’s a solid transmission for cars like the Mazda6 and CX-5, but itÂ’s not meant for sports cars, as we recently found in the automatic Miata RF. So no, this Mazda3 turbo wonÂ’t be a Mazdaspeed. It would simply be a quicker Mazda3, and while we can still pine for a true Mazdaspeed, this will be a welcome addition to the lineup. ThereÂ’s even more ancillary news in the report, too. The docs that Jalopnik saw say weÂ’ll be getting a Mazda3 with a 2.0-liter four-cylinder in 2021. That one has to be the Skyactiv-X engine weÂ’ve been patiently waiting for. It has already launched in Europe, but was delayed in the U.S. Those 100th Anniversary Edition Mazdas get a callout, too. The Mazda3 version of that is reportedly set to be equipped with the turbo engine, making that particular model even more enticing.

2019 Mazda3 shows off factory bodykit, Miata gets a hardtop at Tokyo Auto Salon

The 2019 Mazda3 wasn't exactly lacking in the sporty style department when it was shown last month in L.A. But everyone, including Mazda, knows that doesn't mean it can't be even sportier. As such, the company is showing off a version of the new compact hatchback at Tokyo Auto Salon, a modified car and aftermarket parts show, with a body kit. It's a subtle one, consisting of a black front lip spoiler, black side skirts, and a longer, slightly upturned rear spoiler. Its low-key design fits in well with the Mazda3's taut, clean lines, and it makes the car look lower and more purposeful. The Mazda3 isn't the only car getting some love at the Tokyo Auto Salon. The company will display an MX-5 Miata with a removable hardtop made of carbon fiber. Now, you may remember that Mazda does offer a hardtop, but just for racing drivers. That top is a bit odd looking with a really high rear-end to clear motorsports-spec roll bars and cages. This top follows the lines of the roadster's soft top, looking much more sleek. Neither sets of parts here have been announced for production, but we wouldn't be surprised to see them show up as Mazda accessories. The Mazda3 body kit in particular seems a shoe-in, since the previous generation Mazda3 had a very similar appearance package available. The Miata top certainly seems as though it was designed with regular consumers in mind. Its future is less certain, though. For one thing, Mazda can point to the Miata RF if you want a solid roof. Then again, Mazda still offered a removable hardtop for conventional Miata roadsters even after the original power-retractable hardtop model was introduced. If it does come to market, though, expect it to be made from more affordable fiberglass and be painted in factory colors. Related Video: This content is hosted by a third party.
