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.

Toyota CamRally is vanilla spiced

We weren't quite sure it was possible, but NASCAR driver Parker Kligerman and the other folks behind this Toyota Dream Build Challenge vehicle (check out the other cars in the challenge) have made the Camry, a versatile but vanilla family sedan, into a performance car to be reckoned with. And by stripping it (literally) of its versatility and injecting some spice into it, this rally-spec Camry does indeed appeal to the enthusiast crowd.
The appeal starts with the CamRally's vintage Toyota racing colors of red, orange and yellow painted on a widened body. Those wide fender flares and rocker panels, paired with the revised front and rear fascias (and massive rear spoiler), lend the car an aggressive look without being tacky, and enhance the aerodynamics. But peel back the skin and you'll find plenty of performance upgrades to back up the looks.
While Toyota doesn't say how much horsepower it makes, the CamRally's V6 is turbocharged, and we assume the car's brake upgrade is indicative of the engine's increased output. The stripped interior only contains what's needed for rally racing, including bucket seats, a motorsport steering wheel covered in Alcantara, a carbon-fiber dashboard and a roll cage.

2020 Hyundai Palisade vs. Ascent, Pilot, Highlander and CX-9: How they compare on paper

We've finally had our first drive of the 2020 Hyundai Palisade and found it to be well-equipped for sales success. It nails the formula that some of the most successful three-row crossovers have, the aforementioned seating capacity, high driving position, all-wheel-drive availability and a V6 engine. Of course, it also offers a unique and menacing-looking exterior that ought to stand out in the parking lot. To dig deeper into how it compares to other three-row family crossovers, we've fired up the old Autoblog Comparo Generator 3000 (™) and lined the all-new 2020 Palisade up against the 2019 Subaru Ascent, 2019 Honda Pilot, 2019 Toyota Highlander and 2019 Mazda CX-9. Besides being two of last year's best-selling three-row SUVs, the Pilot and Highlander are also the closest in general concept to the new Palisade, while the Ascent and CX-9 also offer a comparable turbocharged four-cylinder powertrain. The CX-9 is also one of our favorites in the segment, and the Ascent is one of the newest entrants on the scene. There are of course numerous other worthy contenders, including the Chevrolet Traverse, GMC Acadia, Volkswagen Atlas, Nissan Pathfinder, Hyundai Santa Fe and the best-selling Ford Explorer, so if you want to see their specs, check out the Autoblog compare tool. Performance and fuel economy The Subaru, as is so often the case, is the oddball. It has a 2.4-liter turbocharged horizontally opposed four-cylinder (aka a flat-four or a boxer-four) that produces a comparatively modest horsepower rating, but a greater amount of torque. That's typical for turbocharged engines such as Mazda CX-9's turbo inline-four that produces 250 horsepower on premium fuel (227 hp on 87 octane) and 310 lb-ft of torque (the VW Atlas also offers a base turbo-four). The Hyundai, Honda and Toyota, meanwhile, go about it the old-fashioned way, with naturally aspirated V6 engines displacing 3.8 liters in the Hyundai, and 3.5 liters with the two Japanese crossovers. The Toyota and Hyundai lead the pack in horsepower, with the Toyota taking top honors by just 4 horses. The Honda weighs less, though, so their acceleration should be comparable. The Subaru actually accelerates on par with its V6-powered competitors, probably due in part to its continuously variable transmission. The fuel economy trophy goes to the Ascent.
