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.

Everything new at the 2019 New York International Auto Show

Transcript: Welcome to the 2019 New York Auto Show. It's the last auto show, and so far it's my favorite of the year. We have a new buggy, compact pickup and trail ready SUV from Volkswagen. Ford brought the new Escape and a new Mustang performance variant, and we have a brand new Toyota Highlander and Subaru Outback. Let's go take a look around. We're here at the New York Auto Show with the Subaru stand. Normally the Subaru stand is just some white carpet and some show lighting. This year it's like we're in a national park. It's ... Frankly, I'm from Oregon. You're from Colorado. Yeah. It's making us feel at home. And in that way what better place and what better people to introduce this Subaru Outback which is pretty much the official car of Colorado and Oregon. Yeah. You actually have to buy a Subaru before they let you move to Colorado. Now instead of climbing up there and taking a look because we've been told we can't do that we're gonna go over there and check out another one. So the exterior, not that different. No. Looks exactly like an Outback. There's actually oddly a little more black plastic trim on the outside. A little too much for me. Right. It's interesting because it kind of slowly went away from that from the beginning because in the beginning the black plastic trim kind of made it an Outback, and now they're kind of bringing it back. I guess they needed to make it more macho. Right. Right. Now we're inside. Inside it looks pretty different. Swank. It's kind of swank for an Outback which has been pretty plain. Now this is the newly available vertically gigantic touch screen here. 11.6 inches. That is massive. This is how big it is when it's turned on ... just for the viewers. Now this is the onyx trim. So with that you get the black mirrors, the black wheels. This upholstery is special to the onyx, so it's gray and black and you also have this green stitching. Yeah, I like this accent stitching. It's kind of neat. Oh there's also a little tray there. Well this is a deep bin here. You can probably fit a phone. There we go. Almost. Yeah there are two USB ports. There's an additional two in the backseat. So this thing here you pop in the cup holder and it gives you a little more space or less space. These are really big, so if you have one of those Nalgene bottles I'm guessing it's going to fit in there. One of my complaints about my Subaru that I own now which is a naturally aspirated Crosstrek is that up in the mountains. It's slow?

Successor to the Toyota 86 is on the way

Until now, Toyota and Subaru have been mum on the prospect of a follow up to the Toyota 86 and Subaru BRZ. Although both cars received mild refreshes and even milder power bumps, they're both essentially the same cars that hit the market nearly five years ago. It appears a successor is indeed on the way, as Autocar confirms that Toyota is developing a next-gen 86. Karl Schlicht, executive vice-president at Toyota Motor Europe, said that the 86 will live on past the current generation. "The car serves a big purpose," Schlicht said. "We are not getting out of that business. Sporty cars go through their phases. It's our intention to continue with that car." Toyota seems to be back in the sports car business, as the company has partnered with BMW on a new Supra. Like the current Toyota 86, it seems likely that the successor will be co-developed with Subaru. Schlicht says that to get the low center of gravity and the handling characteristics that come along with it, a horizontally opposed engine is a necessity. He admits that there is no firm confirmation of a commitment from Subaru. While no Schlicht gave no details about the new car, he did nix any possibility of a convertible variant. "We wouldn't do it on the current model," he said. "That doesn't mean dealers wouldn't like one, but there are so many other priorities that I don't think we've got spare capacity for that."
