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.

2018 Jeep Wrangler might get power sliding roof panels

A user at JL Wrangler Forums snapped a few photos of a prototype 2018 Wrangler driving around, and one of the shots revealed some interesting switchgear. On the ceiling are a couple of handles that further confirm it will still have a multi-piece removable roof, something already expected when images of the truck leaked out. Just ahead of those handles is a binnacle of switches with no clear explanation for their existence. The folks at JL Wrangler Forums believe they have the answer. They suspect that the controls are for a Jeep Renegade-style My Sky roof. In case you forgot, the Renegade's My Sky roof is a cross between a sunroof and the Wrangler's removable roof. One of the panels can slide back like a sunroof, or it and a second panel can be pulled out entirely. The forum members believe the large center button and smaller buttons ahead of it are controls for sliding back either or both front roof panels. Of course the roof panels will still be removable, too. They also cite anonymous sources that say the forum's speculation is on the right track. A few years ago, rumors of a power top were circulating, too. We can certainly see this as a possibility. It would offer Wrangler owners the option of some open-air fun without requiring the unfastening of multiple latches and stowage of large roof panels. Although it would likely add plenty of cost, that won't be much of an issue for Jeep. It's already possible to spend remarkable amounts of money in heavily accessorized Wranglers, and Jeep doesn't have trouble getting them sold. We're still not completely convinced, though. It's also possible we could be looking at switchgear for overhead lights or other interior features, maybe even storage for sunglasses. We just can't be positive without getting a closer look at the switches. Also, there's at least one reason Jeep might want to avoid a feature like this. Power sliding top panels could add weight. Now Jeeps aren't amazing performers, save for the SRT and Trackhawk Grand Cherokees, so speed won't be an issue, but if the weight goes into the top panels, it could make top removal more difficult thanks to heavier components. We'll have to wait to find out for sure. Related Video:
