EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.

Here are the best-selling cars and trucks from January 2015

Every month, Autoblog slogs through all the sales figures reported by automakers that do business in the United States, and, after a little bit of sorting, we put it into an easy-to-read chart in an attempt to make it as easy as possible to follow the ins and outs of sales and shipments. But that only covers the brands themselves, not the individual models they sell. And we think you'd all be interested in knowing which vehicles beat their rivals in sales from month to month, so we've put together this handy gallery to keep you in the know. While the leader of the pack may not come as much of a surprise, the order that the top ten finishes in changes frequently – due to automaker deals, the price of gas, etc. – and we've included some statistics to help you see how their current performance stacks up to month's past.

Ram goes all-in on SAE J2807 tow ratings [w/video]

Thanks to the Society of Automotive Engineers (SAE), when car shoppers look at horsepower and torque figures on vehicles, they know that all the automakers are calculating them the same way. However, that isn't the case when it comes to truck buyers and max towing capacity ratings because each company figures the value differently. That practice finally changes with the SAE's standardized J2807 system, though, and Ram Truck is the first one to apply the new test procedure to its entire light- and heavy-duty pickup range.
All models of the Ram 1500, 2500 and 3500 use the new, standardized rating for the 2015 model year, but buyers might not notice too much difference. According to the company, in 99 percent of cases the max towing weights are unchanged or even improve slightly from last year. That's a strong result compared to the 2015 Chevrolet Silverado and GMC Sierra that are seeing few increases but mostly decreases under the new testing procedure.
"For too long, an uneven playing field existed and towing capacities went unchecked. We're happy to be the only pickup truck manufacturer to align with the SAE J2807 towing standard across our pickup truck lineup," said Mike Cairns, director of Ram Truck engineering, in the company's announcement of the new specs.
