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-Kia claims 'greenest' title from Honda, Big Three still big losers

Let's start with the good news. On average, any new car you buy in the US today will be 43 percent cleaner than any average new car in 1998. Here's some more good news, for Korea anyway, Hyundai-Kia has been named the cleanest automaker in the latest study by the Union of Concerned Scientists (UCS), which looked at 2013 model year vehicles sold between October 2012 and September 2013 from the top eight automakers (by volume). The bad news? The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The big three Detroit automakers are, on average, still making the dirtiest cars in the showroom. The problem for Ford, General Motors and Chrysler lies in their trucks, which sell well but tend to have pretty bad fuel economy (compared to sedans, at least). The UCS calculates its list by averaging "the per-mile emissions for each light-duty vehicle sold by each automaker" and then factors in "the fuel economy, fuel type, and sales volume of each type of vehicle sold by each automaker" and "the upstream global warming emissions from producing and distributing the fuel used by each vehicle, as well as emissions from the vehicles themselves." That all means that, the more trucks you sell, the worse you're gonna do. Then again, the more trucks you sell with 18 mpg, the more you're helping drivers put CO2 into the air, so the UCS is doing a fair comparison of the things that this study is trying to track. More details on the methodology are available on page six of the study PDF. In case you were wondering (we were), UCS did make sure to use the revised mpg numbers for Hyundai and Kia models that were originally overstated. Hyundai has apologized for and fixed those figures and even with the new, corrected numbers, Hyundai's total emissions are dropping at a rate of about three percent a year, enough for it to take the greenest company title for the first time. In fact, this is the first time that an automaker other than Honda has come out on top in the UCS ranking, which has been released six times now, including the first one in 2000 (which looked at 1998 model year data). In 2010, Honda was almost knocked off the winner's perch by both Hyundai and Toyota, but managed to hold on. Chrysler, on the other hand, came in dead last (again) in the ranking of the top eight automakers, snagging the "dirtiest tailpipe" award once (again). Read the UCS' press release below.

Recharge Wrap-up: Peugeot eF01 folding e-bike, Australia orders Hyundai FCEVs

Australia has ordered 20 hydrogen powered vehicles from Hyundai. The Australian Capital Territory Government in Canberra will take delivery of the fleet of Hyundai's next-generation fuel cell vehicles (set to replace the Tucson Fuel Cell in 2018) for its Renewable Transport Fuels Test Berth project. As part of the program, the vehicles will be powered by hydrogen made with a Siemens Silyzer System with electricity from Hornsdale Wind Farm in South Australia. The Siemens refueler is capable of powering over 1, 000 fuel cell vehicles each averaging 14,000 miles per year. Read more from Hyundai. Peugeot has unveiled its eF01 electrically assisted folding bike. Meant to facilitate multimodal travel, Peugeot's eF01 folds up quickly to be thrown in the trunk of a car, carried on public transport, or wheeled in its folded position while walking. It's a little hefty, at 37 pounds, but its compactness helps make up for that. It can be charged in the cargo area of any vehicle with a 12-volt outlet, so it's ready to provide 18 miles of electric assistance at speeds of up to 12 mph. It can also communicate with a smartphone via Bluetooth to show current charge and range. Read more from Peugeot. A123 Systems will collaborate with Argonne National Laboratory to create safe, better performing lithium-ion batteries. The partners will focus on cathode technology in order to increase energy density and durability in order to improve the driving range of electric vehicles. A123 expects to increase energy density and range by more than 60 percent over its current offerings. "Working with Argonne will further advance our already strong presence in plug-in vehicles and support the increasing market demand globally," says A123 Systems CEO Jason Forcier. "We look forward to expanding our customer base as we offer increasingly greater range to our plug-in vehicle programs without compromising on the life and safety performance that the market has come to expect from A123."
