Are old airbags killers?

Takata airbags may not be the only ones with some very serious problems. A new report from TheDetroitBureau.com claims that the National Highway Traffic Safety Administration has opened its second investigation into bad airbag inflators, and this time, they aren't from Takata. The focus of this latest case is on the airbag inflators in some 500,000 older Chrysler Town and Country minivans and Kia Optima sedans, all of which come from ARC Automotive. While the Takata case looks at problems stemming from the engineering and production process, the ARC investigation focuses on the age of the inflators. As TDB explains, airbag inflators are essentially what the military refers to as shaped charges, sort of like Claymores (for fans of the Call of Duty series). In combat, they blow up in a specific direction, protecting those behind the explosion, although in the case of airbags, the explosion "[creates] a precise rush of hot gases" that inflate the bags. NHTSA's worry is that with the increased average age of today's vehicles, years and years of being bounced, jolted, and shaken about and exposed to often-radical temperature changes have altered the nature of the explosives in these vehicles, causing too big of an explosion. "It may be a reasonable assumption that as these things age they deteriorate." – Analyst George Peterson "It may be a reasonable assumption that as these things age they deteriorate," analyst George Peterson told TheDetroitBureau.com. NHTSA boss Mark Rosekind backed up aging angle. "Cars are lasting on the road a lot longer than ever before," Rosekind told TDB, adding that seals could start breaking down. "Is aging now an issue? That's part of the investigation going on." NHTSA has only identified two "incidents" so far, although according to Center for Auto Safety Director Clarence Ditlow, there's genuine concern that there could be additional unidentified cases. "Could we have missed more? That could be the case," Ditlow told TDB, citing the misidentified deaths in the Takata investigation. Ditlow was quick to point out that, even in older vehicles, airbags are much more likely to protect than harm. "No one is saying you should disable your airbags," the safety advocate told TDB. "You're far more likely to be helped than hurt by one if they go off." At least one automaker, meanwhile, has already been advised of the investigation by NHTSA and is checking its airbags.

Hyundai's rakish HND-9 concept has lots of Seoul

Hyundai has unwrapped the HND-9 Sports Coupe Concept at the 2013 Seoul Motor Show. The design study is intended to give the world a glimpse at what Hyundai has planned for the look of its future products - an evolution of the automaker's current Fluidic Sculpture design language.
With classic front-engine, rear-wheel-drive proportions, the HND-9 looks great, and engineers graced the concept with a 3.3-liter turbocharged, direct-injection engine good for 364 horsepower. An eight-speed automatic transmission shuttles that thrust to the rear wheels, while touches like butterfly doors give the machine a bit of flair.
Indoors, the HND-9 features seats built with a special mesh that changes colors depending on the viewer's angle. Designers modeled the cabin after a cockpit for a close, sporty feel. You can check out the full press release below for more information.

Average new-car fuel economy figures continue record pace

Manufacturers are making more efficient cars and trucks; we've known that to be true for some time. Nearly every new car has some sort of trick to eke a few extra miles out of every gallon of fuel. Whether that be turbocharging, active aerodynamics or hybrid technology/electrified powertrains, the fact is that our vehicles are more efficient than ever before.
Thanks to a recent study by TrueCar, we've got fresh quantitative data to support the above statements. For the fourth month in a row, we've seen an improvement in national fleet fuel economy. We Americans are 0.7 miles per gallon more efficient than we were last month, and our cars are 1.6-mpg better than at this time last year. That said, we're still down on 2013's high, which was set back in January at 24.5 mpg.
Not only does this reflect the improved technologies in our vehicles, but it demonstrates a changing mindset among consumers, who are purchasing more efficient vehicles despite the relative stabilization of fuel prices. Every fuel-efficient model sold drives its manufacturers fleet average up.
