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.

Labor Day: A look back at the largest UAW strikes in history

American made is almost an anachronism now, but good manufacturing jobs drove America's post-war economic golden age. Fifty years ago, if you held a job on a line, you were most likely a member of a union. And no union was more powerful than the United Auto Workers. Before the slow decline in membership started in the 1970s, the UAW had over 1.5 million members and represented workers from the insurance industry to aerospace and defense. The UAW isn't the powerhouse it once was. Today, just fewer than 400,000 workers hold membership in the UAW. Unions are sometimes blamed for the decline of American manufacturing, as companies have spent the last 30 years outsourcing their needs to countries with cheap labor and fewer requirements for the health and safety of their workers. Unions formed out of a desire to protect workers from dangerous conditions and abject poverty once their physical abilities were used up on the line; woes that manufacturers now outsource to poorer countries, along with the jobs. Striking was the workers' way of demanding humane treatment and a seat at the table with management. Most strikes are and were local affairs, affecting one or two plants and lasting a few days. But some strikes took thousands of workers off the line for months. Some were large enough to change the landscape of America. 1. 1936-1937 Flint Sit-Down Strike In 1936, just a year after the UAW formed and the same year they held their first convention, the union moved to organize workers within a major manufacturer. For extra oomph, they went after the largest in the world – General Motors. UAW Local 174 president Walter Reuther focused on two huge production facilities – one in Flint and one in Cleveland, where GM made all the parts for Buick, Pontiac, Oldsmobile and Chevrolet. Conditions in these plants were hellish. Workers weren't allowed bathroom breaks and often soiled themselves while standing at their stations. Workers were pushed to the limit on 12-14 hour shifts, six days a week. The production speed was nearly impossibly fast and debilitating injuries were common. In July 1936, temperatures inside the Flint plants reached over 100 degrees, yet managers refused to slow the line. Heat exhaustion killed hundreds of workers. Their families could expect no compensation for their deaths. When two brothers were fired in Cleveland when management discovered they were part of the union, a wildcat strike broke out.

2017 Chrysler Pacifica Hybrid scored 84 MPGe in government testing

The 2017 Chrysler Pacific, in non-hybrid form, was already at the top of the minivan heap in terms of EPA-rated fuel economy. Now the government agency has released its official test numbers for the Pacifica Hybrid, and they're looking pretty good. The non-hybrid Pacifica achieved 28 highway, 18 city, and 22 combined miles per gallon, which compared favorably to the 2016 Honda Odyssey's 28/19/22 and Nissan Quest's 27/20/23 ratings. You can read more about the regular Pacifica's scores right here. But none of these vans compare to the Pacifica Hybrid, which is incidentally the only hybrid in the class. FCA claims that the EPA's numbers are even better than the anticipated 80 MPGe, although we can't speak to whether that's an honest admission or a too-convenient claim. But there's no denying that the official rating – 84 MPGe – is impressive. If you aren't familiar with the MPGe rating, no worries. It's not as straightforward as conventional EPA MPG ratings, but a layperson can understand how it works. MPGe stands for miles per gallon equivalent, and measures fuel economy based on the energy content of a gallon of petroleum-based gasoline. For those who like formulas, the Automotive X Prize once defined MPGe as (miles driven) / [(total energy of all fuels consumed)/(energy of one gallon of gasoline)]). As for a conventional rating, the EPA only provides a combined city/highway number on the Monroney sticker, and an FCA spokesperson told us that the rating for the Pacifica Hybrid will be 32 MPG. This represents the hybrid working as normal, not in EV-only mode. It's also an improvement of almost 10 MPG over the combined ratings of the top three conventional minivans in the segment, including the non-hybrid Pacifica. Range is also fantastic. The EPA rated the total EV-only range as 33 miles, and the overall combined range at a staggering 566 miles. And that's from a fuel tank that's just 17 gallons (compared to the 19-gallon tank in the conventional Pacifica, which nets it a 418-mile EPA-rated range). FCA is going to extraordinary lengths to credit its eFlite transmission-generator unit, which can supply electric power to the front wheels if necessary. It's a piece of equipment that represents a substantial engineering investment, and apparently that's all paid off. Chrysler tells us that the Pacifica Hybrid will go on sale next month, and that dealers will get more volume in Q1. Related Video: This content is hosted by a third party.
