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 GT86 CS-R3 ready to rally

Toyota is returning to the rally scene with the competition-spec version of the GT86. First announced over a year ago, the GT86 CS-R3 began testing this past summer, and is now just about ready for customer deliveries. Instead of contesting the top tier of the World Rally Championship, the GT86 CS-R3 was designed to compete in the R3 class. It's closely based on the road-going model (better known around these parts as the Scion FR-S), and retains its 2.0-liter boxer four, sending 238 horsepower and 170 pound-feet of torque through a Drenth six-speed sequential gearbox and limited slip differential to the rear wheels. Available in either tarmac or gravel specification, the GT86 CS-R3 comes complete with "body shell, powertrain and all mechanical components required to build the car." It's set to undergo final FIA certification in July, at which point it'll be ready to deliver to privateer rally teams to field in national and international rallies and in the HJS TMG CS-R3 Trophy that kicks off in Germany on July 4. The package sells for ˆ84,000 ($94k at today's rates) before taxes, but customers who place their orders before April 24 will get a ˆ5k discount.

Cologne, Germany - The CS-R3 prototype was launched last August and since then has completed an extensive test programme to optimise design and define the final specification of the kit which will be delivered to private competitors and teams. Detailed development has generated improved performance on both gravel and tarmac, while reliability and durability have been prioritised in order to deliver a car which allows cost-effective competition throughout the season and beyond. The CS-R3 has already proved immensely popular thanks to its rear-wheel drive powertrain, with 1,998cc, 238hp boxer engine and six-speed sequential transmission which combine to produce a spectacular driving experience. The first cars will be delivered to customers in May, later than originally forecast to allow improvements highlighted during testing to be implemented. As a consequence TMG has extended its introductory discount.

Meet the Most Elegant Automobile, and it's for sale

Alright, so maybe "most elegant" is a bit of a stretch, but we feel safe in calling the 1992 Toyota Paseo in the video below an "automobile." High praise, we know. Still, it's clear someone loves the awkward little coupe enough to produce a hilarious video to sell the thing. Henry Floyd worked up a quick parody of the over-the-top luxury car ads we all know and loathe, and while the finished product is a little skimpy on details like price or location, it certainly doesn't hold back on the exposition.
Hell, if we didn't already have a parade of horrible ideas floating around our collective driveways, we might even be convinced to give this little heap a new home. You can check out the ad for yourself below, just don't be surprised if you find yourself with a burning desire to own a Paseo.
