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.

2017 Kia Cadenza First Drive

"Garbanzo? Costanza? Credenza?" I can't tell if the guy at the bakery is trying to be funny or if he's genuinely forgetting the name of the car – I've told him twice; it's the 2017 Kia Cadenza. But you know, maybe the miscommunication is just fine. Like the Cadenza itself. It's fine. You shouldn't read that negatively. Every now and then in this job, you drive a car and simply come away thinking, "it was fine." And if you're building a car in this particular segment, that's practically the response you hope to elicit. A comfortable jack-of-all-trades at a price that isn't going to bankrupt the owner. Consider the Cadenza's competition: Toyota Avalon, Nissan Maxima, Chevrolet Impala, Buick LaCrosse. These aren't groundbreaking luxury vehicles, masters of utility or fuel economy, or Nurburgring-smashing sports sedans; they're... fine. You almost feel bad saying it – from a very reasonable angle it's a great segment, populated with cars offering a lot of the same equipment and a little more bang for the buck than a full-on luxury sedan, and tending to be roomier, too. And yet it's that dilution of dedicated purpose that keeps these models stagnant in showrooms compared to the more luxurious – and certainly to the more economical. It's hard to raise an eyebrow here. So it goes with the Cadenza. Despite looking a heck of a lot like the previous car, the new Cadenza has been reworked significantly – the use of high-strength steel has doubled, to over 50 percent; the use of hot-stamped steel has tripled; the doors are 16 percent more dent-resistant; the chassis has 35 percent greater torsional rigidity; there's a new subframe (similar to that of the Optima); the front windows are now laminated and there's 13 percent more sound insulation in the A-pillars; there's a full underbody cover and wheel air curtains; it has a new eight-speed transmission – developed in-house; there are 40 fewer pounds of unsprung weight thanks to aluminum parts; the brakes are bigger; and there's a bevy of upscale tech features – but we lost you halfway through that paragraph. The styling is a little sharper than the outgoing model's – it's not going to blow your pants off, but it's hardly a bad-looking car. The updated design features Kia's now-trademark quad-LED setup within the lower front grilles, and the main grille is a concave affair – base models get a "Diamond Butterfly" insert you know from other Kia models, and higher-end Cadenzas get "Intaglio" vertical slats.

Refreshed Kia Optima Hybrid continues to blend good looks and efficiency

With all the excitement at the Kia stand surrounding the new Soul EV, it's easy to forget that there were other cars on display at the Korean marque's Chicago Auto Show display. The Niro Concept from the Frankfurt Motor Show made an appearance, but the other production model on display was the refreshed Optima Hybrid (which was tucked away in a corner).
Like the standard Optima, which was refreshed at the 2013 New York Auto Show last year, the hybridized sedan gets a slightly restyled face and rear end. As we told you in our official post on the car yesterday, the gas-electric powertrain of the 2014 Optima Hybrid still deploys 199 total system horsepower and 235 pound-feet of torque. Buyers of the base LX car will net 36 miles per gallon in the city and 40 on the highway, while the upmarket EX loses a mile per gallon in both environments.
Have a look at our live gallery of the new Optima Hybrid, from the floor of the Chicago Auto Show.
