Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Mazda recalls 1.37 million older vehicles for ignition switch short [UPDATE]

UPDATE: Mazda has confirmed to Autoblog that NHTSA's figures and list of effected models are accurate. Mazda is recalling 1,368,500 older vehicles in the US that date as far back as the late '80s because a potential short circuit in the ignition switch could cause a fire. According to the National Highway Traffic Safety Administration, the models include: 1990-1995 323 1993-1998 626 1993-1995 929 1989-1998 MPV 1993-1997 MX-6 1992-1993 MX-3 1990-1998 Protege Mazda reports that over time the grease around the switch's contact points can carbonize and become conductive, which can eventually lead to a short circuit. In some cases this results in smoke, but it could also lead to a fire. According to company spokesperson Tamara Mlynarczyk to Autoblog, there're no accidents, injuries, or fires in the US. Once the vehicle is running, the potential fault also doesn't affect drivability. Documents from NHTSA (as a PDF), indicate there was a fire in one of these vehicles in Japan in 2002 that could have been linked to this issue. The recall should begin in December. In its announcement of the issue below, Mazda reports 1.2 million vehicles affected and includes the 1990-1996 323/Protege. Autoblog has reached out to the company to understand the discrepancy.

In the affected vehicles, grease applied to the contact points inside the ignition switch may become conductive and overheat. CONSEQUENCE: If the ignition switch overheats there would be an increased risk of a fire. REMEDY: Mazda will notify owners, and dealers will replace the ignition switch, free of charge. The recall is expected to begin December 15, 2015. Owners may contact Mazda Customer Experience Center at 1-800-222-5500, option#6. Mazda's number for this recall is 8715J.
