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.

Jeep marks 75th anniversary in Detroit with special editions

It's been 75 years since the Jeep brand was founded. To celebrate the occasion, the sport-ute manufacturer has rolled out an array of six special editions – one for each model in its lineup. And they've each marked their debut here in Detroit. The 75th Anniversary Editions of the Wrangler, Renegade, Cherokee, Grand Cherokee, Compass, and Patriot are all decked out in green – though the exact shade differs between models, and they can be ordered in different colors for those who prefer. Either way, the bodywork is offset by bronze trim, mesh fabric interiors, and all the special-edition badges you could ask for. And in true Jeep style, they all offer some degree of open-airedness, even if that just means a sunroof. Of course, bringing back the Wrangler pickup and Grand Wagoneer – both of which are planned for this milestone year – would be agreeable as well, as would a Hellcat-powered Grand Cherokee SRT. But for now these special editions strike us as suitable a way as any to celebrate three quarters of a century of rock-crawling. Check 'em out in the gallery above of live images from the floor of the Detroit Auto Show for a closer look before they reach dealers in the first quarter of this year.
