Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.

Toyota recalls 1.37 million more vehicles for Takata airbags

Toyota is expanding its passenger-side Takata airbag inflator recall campaign by an additional 1.37 million vehicles in the United States. The models covered under this broadened recall are the 2003-2007 Corolla, Matrix, and Lexus SC430; the 2005-2006 Tundra; and the 2005-2007 Sequoia. In total, Toyota says that this expansion brings the number of its vehicles covered under the Takata inflator recall in the US to 2.915 million. For these latest models, owners will be notified by mail soon. The move is similar to a recent decision by Honda to broaden its recall list. As with millions of other vehicles covered under these recalls, it's possible for exposure to moisture to cause the inflator to ignite too quickly in an airbag deployment. This can cause shrapnel to be sprayed at occupants. At least seven deaths have been potentially linked to these ruptures worldwide. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALL TORRANCE, Calif., June 16, 2015 – Toyota Motor Sales, USA, Inc. today announced that it is expanding its recalls involving Takata front passenger airbag inflators. Based on recent information from Takata and the National Highway Traffic Safety Administration (NHTSA), Toyota will recall approximately 1,365,000 additional 2003-2007 Corolla and Corolla Matrix; 2005-2006 Tundra; 2005-2007 Sequoia; 2003-2007 Lexus SC430 vehicles. This brings the total number of Toyota and Lexus vehicles covered by Takata recalls in the U.S. to approximately 2,915,000. In the involved vehicles, the front passenger airbag inflators could potentially be susceptible to rupture when deployed and seriously injure vehicle occupants. "Toyota's focus remains on the safety and security of our customers, and we will continue to respond promptly to new developments so we can resolve issues for them as quickly, conveniently and safely as possible," said Dino Triantafyllos, chief quality officer, Toyota Motor North America. Multiple investigations into the root cause of the potential for inflator rupture are taking place, including by Orbital ATK, an independent engineering firm commissioned by an industry-wide joint testing initiative comprised of the ten automotive manufacturers conducting Takata-related recalls. All known owners of the affected Toyota / Lexus vehicles will be notified by first class mail to return their vehicles to a Toyota / Lexus dealer. The dealer will replace the airbag inflator with a newly manufactured one.

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.
