Toyota Yaris Hybrid-R is road-going version of brand's racing technology [w/video]

Did you know that the Yaris is Toyota's best-selling vehicle in Europe? That may help explain to us Americans why the car that's lowest on the company's totem poll here in the US got turned into an all-wheel-drive hybrid track monster for the 2013 Frankfurt Monster Show.
Called the Toyota Yaris Hybrid-R, this three-door pocket rocket isn't just a hybrid making a lot of horsepower - it incorporates technology from Toyota's TS030 Hybrid racecar that competes in the FIA World Endurance Championship series, including the 24 Hours of Le Mans. The Yaris Hybrid-R packs a 300-horsepower, turbocharged, 1.6-liter four-cylinder engine under its hood, which should be enough for most speed freaks, but Toyota pairs it with two 60-hp electric motors at each rear wheel (the same ones used in the production Yaris Hybrid that's sold in Europe). That makes total system output an insane-for-this-size 420 hybrid horsies.
But that's not all, as the Yaris Hybrid-R forgoes the traditional battery pack below the rear seats in favor of a supercapacitor, which can both hold more energy and has a much faster power charge/discharge speed than traditional batteries. Paired with the supercapacitor is a third 60-hp electric motor/generator positioned between the engine and six-speed sequential transmission. Its job is to feed the super capacitor energy during deceleration and direct its power to the rear electric motors when more grip and oomph is needed.

Toyota recalling select 2014 Camry and Avalon models

Toyota has announced a rather small voluntary recall, affecting 5,650 Avalon and Camry sedans from model year 2014. Both gas and hybrid models are included in the action.
This recall focuses on the left front lower suspension arm, which may have a bad bolt connecting it to the ball joint. If the car hits a big enough pothole - a real concern as we head into winter - or suffers a major impact, the two components could separate, at which point steering control would more or less vanish.
According to Toyota, there have been no crashes, injuries or deaths due to this problem. Toyota is notifying owners, who will need to report to dealers for a free replacement lower suspension arm.

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.
