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.

JLR shares backstage 'No Time to Die' Range Rover Sport SVR carnage

James Bond's latest adventures will take him to Norway and Scotland, as seen in the trailer for the upcoming "No Time to Die." Somewhere along the way, the British spy encounters a pair of Range Rover Sport SVRs, the ultimate high-performance SUV from JLR's Special Vehicle Operations division in one of the movie's centerpiece car chases. Now, the company has given us a behind-the-scenes look at its filming, and the automotive carnage that ensues. The filmmakers wanted to take a Bond action sequence off-road, and chose the Range Rover Sport SVR as the the bad guys' pursuit vehicle. Armed with a JLR product placement deal (Bond drives a new Defender in another part of the movie) the henchmen had no qualms picking one of the most expensive things on the menu. Unfortunately, that also makes is a bit hard to watch when machines that start at $115,000 are totaled as they careen through the air or roll onto their roofs. The SVRs share a 5.0-liter supercharged V8 with the Jaguar F-Type SVR and are the most powerful vehicles in the Land Rover portfolio. With 575 horsepower and 516 pound-feet of torque on tap, translating to a 0-60 time of 4.3 seconds, they're the perfect weapon for chasing a super-spy down a dirt road. As for Bond himself, 007 makes his escape in a decades-old yellow Toyota Land Cruiser Prado. Specifically, it's a 90-series, a smaller version built from 1996 to 2002 that was never sold in the U.S. but remains popular in other parts of the world. The most powerful engine had just 190 horsepower from a 3.4 liter V6 shared with the similar-era 4Runner. Despite the power discrepancy, Bond manages to dispatch the Range Rovers in spectacular fashion. Wait, this is a Range Rover promo, right? "All the stunts are for real, there's nothing that's CGI'ed," said Neil Layton, the film's action vehicle coordinator. "So to make the cars more dramatic on the screen, we had to turn off a lot of safety feature aids that's on there." Interestingly, another non-JLR product shows up in the video as well. The camera car is a blacked out (to minimize reflection in other cars) Ford F-150 Raptor outfitted with a massive rooftop boom. "No Time to Die" is hits the screens on October 8.

Toyota announces GT86 CS-R3 rally car

Toyota Motorsport GmbH has developed cars for all manner of racing, up to and including Formula One and Le Mans. But it got its start back in 1979 in rally competition, winning four drivers' and three manufacturers' titles in the World Rally Championship. And now it's announced a new rally car.
Based on the Toyota GT86 (better known to us as the Scion FR-S), the CS-R3 rally car isn't built to contest the top tier of the WRC, but is being developed to conform to the lower R3 class. That means a six-speed sequential gearbox, limited slip differential and upgraded engine, brakes, aero... the works. It'll retain the road-going model's rear-drive setup, joining the front-drive Yaris R1A in TMG's portfolio of customer rally cars.
Further details are set to be revealed "in the coming months", but the GT86 CS-R3 will benefit from the experience TMG accrued in developing the GT86 CS-V3 (pictured above) for the Nürburgring-based VLN endurance racing series.
