NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.

Mazda MX-30 electric car production begins: Will it get the rotary range extender?

Mazda has officially started production of the electric MX-30. For the time being, the small electric car hasn’t been announced for the U.S. yet. Mazda hasnÂ’t declared otherwise, though, so we still have our hopes up. The first MX-30s are rolling off the line in Hiroshima, Japan. Europe will be one of the first places where these MX-30s end up. The car starts at GBP30,495 in the UK and ˆ33,990 in Germany. That's around $38,000. Certainly expensive, but the price would surely be different here, plus weÂ’d be eligible for the full $7,500 tax credit. Those lucky European customers will be met with an electric car that likes to do things a little differently than others. The modest 35.5 kWh battery pack is good for just 124 miles on EuropeÂ’s optimistic WLTP testing cycle. It would surely achieve a much lower number in the EPA test. Mazda has made it front-wheel drive, placing a single motor on the front axle thatÂ’s good for 143 horsepower. We expect to see the first ones hit the streets in Europe this fall, but thereÂ’s one thing that makes us hold out hope for an American MX-30: the potential for a rotary range extender. Mazda said as much in its 100-year celebration letter: “Later, the company developed a prototype Mazda2 EV with a small single-rotor engine used as a range extender. A similar system could find its way onto the Mazda MX-30, a brand new battery electric crossover SUV arriving at dealerships this year." Assuming Mazda goes through with a rotary range extender, we could see this car coming to the American market. That would up the range considerably and make it a much more viable option for many customers, even if they might not need the added range on a daily basis.  Related video:

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.
