Toyota recalls 250 vehicles in two separate campaigns

Toyota is keeping on top of things by issuing two, small recalls on 2015 model year vehicles. The first covers 230 examples of the 2015 Yaris. In the affected models, the bolts holding the rear axle bearing might not be tight enough. If one of these fasteners falls off, it could possibly damage the rear brakes, including the potential of a wheel locking up. The second, even smaller campaign covers just 20 units of the 2015 Tacoma TRD Pro pickups. In the examples delivered to Puerto Rico, they didn't have the correct placard to advise owners of the correct tire size and pressure on the B-pillar. Neither problem has resulted in any crashes, injuries or fatalities. As usual, affected owners will be notified by mail, and Toyota dealers will repair the issues free of charge to customers. Toyota spokesperson Cindy Knight tells Autoblog that those letters will go out in mid-March. TOYOTA RECALLS CERTAIN MODEL YEAR 2015 YARIS AND TACOMA VEHICLES TORRANCE, Calif., February 17, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced it will conduct a safety recall of approximately 230 Model Year 2015 Yaris hatchbacks and approximately 20 Model Year 2015 Tacoma TRD Pro model pickup trucks. In the involved Yaris vehicles, the rear axle bearing bolts may not have been tightened sufficiently during vehicle assembly. If a bolt is loose and falls off during vehicle operation, the bolt could damage rear brake components, resulting in reduced brake performance or potential wheel lock up, which could increase the risk of a crash. The Tacoma TRD Pro model pickup trucks were distributed to dealers in Puerto Rico without the correct B-pillar tire placard indicating the tire size and recommended cold tire inflation pressure for the front and rear tires. An improperly inflated tire can increase the risk of a crash. Toyota is not aware of any crashes, injuries, or fatalities caused by either condition. Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will repair the vehicles at no cost to the owner.

Toyota Camry to go turbo

As automakers strive to meet regulations, turbocharging is rapidly becoming the norm whether looking at pickups, sports cars or family sedans. However, Toyota remains a stalwart to the changing tide, and for the time being a trip into one of the brand's dealers shows nary a hint of forced induction – probably not for long, though. With models like the Lexus NX 200t and forthcoming IS 200t pointing the way, a big shift is afoot for one of the Japanese automaker's most popular products. Obviously, Toyota is no stranger to forced induction for performance applications like the turbocharged models of the Supra and MR2 in the '90s. But rather than reducing lap times, the latest application is more about improving emissions and fuel economy. According to Automotive News, the Camry is getting a 2.0-liter turbo four-cylinder in the near future as a replacement for its V6 engine option. The 3.5-liter six currently in the venerable sedan already makes 268 horsepower and 248 pound-feet of torque, versus 235 hp and 258 lb-ft in the NX 200t or 241 hp and 258 lb-ft in the IS from the new four. The base four-cylinder also might receive some upgrades. It could grow larger and run on the Atkinson cycle to find improvements, according to Automotive News. There might be a move towards CVTs, as well. Toyota is hardly alone in the shift towards forced induction. Honda is known to have a 1.5-liter turbo mill on the way for the next-gen Civic. In addition, that engine might find its way into the Accord and CR-V as well, according to Automotive News. Among the major Japanese automakers, only Nissan is taking a more measured approach towards forced induction in mainstream models. Rather than going all-in on turbos, the company is expected to shift more of its engines to direct injection to go after fuel economy gains.

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.
