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.

Kia showcasing Optima T-Hybrid concept in Paris [w/video]

At the Geneva Motor Show earlier this year, Kia showcased a new diesel hybrid powertrain. And at the rapidly approaching Paris Motor Show, it will present that new technology in the Optima sedan concept you see here.
Called the Kia Optima T-Hybrid, the concept mates a 1.7-liter diesel with both a turbocharger and electric supercharger to a small electric motor and a 48-volt lead-carbon battery. The mild hybrid setup allows it to travel in electric-only model at low speeds and at cruise, regenerating brake power to recharge the battery. Kia said it chose the lead-carbon battery pack over lithium-ion because it's easier to recycle and does not require active cooling.
Because the powertrain is still under development, Kia isn't saying what kind of fuel economy or emissions figures it gets in the Optima T-Hybrid concept, but it is targeting a "significant reduction" in emissions and fuel consumption, while delivering 15 to 20 percent more power. Check out the system in action in the video below.

Recharge Wrap-up: Kia Soul EV, Renault Zoe range boosts

California has removed its limit on the number of HOV lane access stickers available for plug-in hybrids. While the state removed limits for white stickers for solo drivers of battery electric vehicles to use the carpool lane, the green stickers for PHEVs and range-extended EVs had a limit of 85,000, which was reached months ago. Now, BEVs and PHEVs will each have an unlimited number of access stickers until the program expires on January 1, 2019. Read more at Green Car Reports. Kia could improve the driving range of the Soul EV in order to better compete with newer offerings. While its 93-mile range was competitive with most EVs when it was launched as a 2015 model, the Nissan Leaf and BMW i3 have since surpassed it, and other forthcoming affordable EVs like the Chevy Bolt and Tesla Model 3 will set the bar even higher. As such, Autocar says the Soul EV should get a range boost with a mid-cycle refresh for the 2018 model year. Read more at Autocar, and at Green Car Reports. Renault said to be set to unveil a new Zoe EV with a driving range of over 200 miles. With a debut at the Paris Motor Show in October, the popular European EV hatchback will about double its current range. Using a new battery pack from LG Chem, as well as a smaller, more efficient electric motor, the improved range would help make the Zoe even more popular as people make the switch to electric driving in Europe.
