2014 Kia Optima is better by a nose

Kia is showing off a slew of vehicles here in New York, including the ever-so-slightly refreshed 2014 Optima sedan you see here. The brunt of the changes surround the new front fascia, with repositioned LED lighting above the headlamp units and some new quad-LED fogs rounding of a touched-up front bumper. At the rear, Kia has reworked the taillamps, and of course, LEDs are found there, as well.
Other changes to the Optima for 2014 include the additions of two new displays inside the cabin - a 4.3-inch TFT display in the gauge cluster and a larger, eight-inch high-resolution screen that houses the navigation and infotainment data. There are also new seats inside the Optima, which are hopefully more comfortable and offer better bolstering than the decidedly flat chairs found in the current car, plus Kia has added available new safety features like blind spot monitoring and cross-traffic alert.
The powertrain offerings have not changed for 2014 - base cars still get a naturally aspirated 2.4-liter engine while the SX models get the 2.0-liter turbo. There is, however, a new Drive Mode Select system specifically for the SX, which adjusts transmission shift points and steering weight for a more engaging dynamic, or so we're told. (The Optima Hybrid model did receive upgrades to its battery and electric motor just recently, but those changes technically hit during the 2013 model year - it is not immediately clear if the gas-electric model will receive the updates shown here).

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 Cub Concept wanders over from Seoul

The little machine you see above is the Kia Cub. The Cub first debuted at the Seoul Motor Show, but this is the first time we've been able to see it ourselves in person, so we pointed our camera lenses its way and got to snapping.
According to our men on the show floor, the Kia Cub Concept is "quite good looking," with a squat and funky shape that looks mostly ready for production. With a five-door hatchback shape featuring reverse-opening doors (we'll resist calling them suicide doors... whoops...), this machine doesn't seem to share much design DNA with current Kia products. And that's fine. As much as we like Kia's swoopy line of cars and 'utes, a little shakeup every now and then never hurts.
We're sure the diminutive hatchback would be a fun car to pilot, with 204 horsepower and 195 pound-feet of torque coming from its turbocharged and direct injected 1.6-liter four-cylinder engine. Kia quotes a 0-62 time of 7.7 seconds and a top speed of 143 miles per hour. Sounds to us like it could be a worthy competitor to such successful sporting hatchbacks as the Mini Cooper S and Fiat 500 Abarth.
