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 Wrangler pickup's rear suspension is inspired by Ram

Although we've learned about all there is to know about the new Jeep Wrangler, there is still more to discover about its upcoming truck sibling, such as the rear suspension. We knew it would be coil-sprung, but these new spy shots also indicate that the suspension is more similar to what's under a Ram 1500 than the Wrangler SUV. In the gallery above, the first two images compare the rear suspension of a new-generation 2018 Wrangler (left) and the Wrangler pickup (right). Immediately obvious is that the shocks on the Wrangler SUV are mounted at the back of the axle, while the truck's shocks are mounted at the front. It's also possible to see that the anti-roll bar on the SUV is mounted quite high up, while the truck's bar sits much lower, near the base of the rear axle. The third image shows a Ram 1500 on the left and the Wrangler pickup on the right. Here we can see that the Ram shares the same sort of low-mounted anti-roll bars and forward-mounted shocks, along with a Panhard rod. The two aren't quite the same, though. For one thing, the Wrangler pickup's rear axle looks more like the Wrangler SUV's than the one on the Ram. It's possible that these suspension changes were made in an effort to boost the Wrangler truck's payload capabilities. It's also possible that there are some handling quirks to the long truck body style for which a Ram-style suspension was better suited. We'll look forward to learning more about the differences when the truck is revealed, likely in early 2019. Related Video: This content is hosted by a third party.

Next-gen Jeep Wrangler to get 8-speed automatic and 3.0-liter EcoDiesel

Following up on previous reports, an anonymous source within FCA has confirmed to Autoblog that the next-generation Jeep Wrangler will come to market with both a 3.0-liter, EcoDiesel V6 and ZF's critically acclaimed eight-speed automatic transmission. While this pairing makes a lot of sense (we'll explain why in a minute), until now, we only had limited reports that either item would arrive in the next-generation Wrangler. This is the first time we've heard that the eight-speed automatic and the diesel would be paired together. That said, we shouldn't be surprised by this news. FCA currently sells the Jeep Grand Cherokee and Ram 1500 with the diesel/eight-speed gearbox combo, making its inclusion in the next-gen Wrangler far from an Apollo 11-caliber feat of engineering. Naturally, we reached out to Jeep for an official comment. Spokesperson Gabrielle Schulte gave us the expected response to this kind of inquiry, telling Autoblog that FCA does not comment on future product. Jeep has flirted with the idea of a diesel Wrangler for some time, with CEO Mike Manley telling Ward's Auto just over two years ago that a Wrangler diesel was "on the radar," although at that time, we weren't certain whether it'd be the 3.0-liter EcoDiesel showing up in the rough-and-tumble off-roader. As for the eight-speed, SEC filings back in November revealed that it'd be coming to the Wrangler in 2018. Our source could not confirm which model year the 8AT/diesel would arrive in. Related Video:
