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 Scrambler pickup truck spy shots reveal top and lighting details

Several spy shots have come out that give us further insight into the new Jeep Wrangler Scrambler pickup truck. Among them are some photos of a prototype being driven near FCA test facilities. They show that the Wrangler will have LED headlights available similar to those on the SUV model, as well as the new Renegade revealed for Europe. They also show the taillights of the pickup, though they appear to be units from a previous-generation JK Wrangler. They're probably placeholders for the new model's lights. View 22 Photos These photos also include images of the truck's interior. The dashboard is a mash-up of old pieces, including a JK Wrangler dash, and a Chrysler-badged steering wheel. But the important part of these photos is that they show parts of a normal Wrangler SUV roll cage, and latches holding down roof panels. These are evidence that the production model will have a removable roof. Further evidence comes from photos taken by someone from the Jeep aftermarket part company Artec Industries was checking out the factory in Toledo, Ohio. The images were brought to our attention by Jeep Scrambler Forum, and they show an unfinished Wrangler pickup body sitting in the doorway to the painting facility. The photo is below, and it confirms a number of details. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. This body has the same style of roll cage as those found on the SUV versions of the Wrangler. Specifically, it looks like a combination of the upright rear cage of the two-door, with the length of the Wrangler Unlimited's cage. In addition to confirming the removable top, the windshield also appears to fold down, too. Beyond the confirmation of the top and windshield features, the rest of the cab looks almost identical to any other 2019 Wrangler Unlimited. The fenders and hood are the same, down to the fender vents, as are the doors. The cab shows that there was clearly room for full-size doors, which would have been welcome from an access perspective, but that would naturally cost more than already developed parts, It also means that any aftermarket doors or door accessories created for the Unlimited will work with the Scrambler. We can also see that there's a small diagonal indent in the cab where part of the rear fender will fit. It also matches up with the line of the rear door.

Buy this instead of a Wrangler | 2017 Jeep Grand Cherokee Trailhawk Review

In our first encounter with the 2017 Jeep Grand Cherokee Trailhawk at Fiat Chrysler's Chelsea Proving Grounds, we saluted the new model's impressive on-road demeanor. In its off-road mode, however, we couldn't ignore the pre-production throttle calibration – it was super sharp and difficult to modulate with the precision needed to navigate obstacles. We were told then that Jeep's engineers were aware of the problem and were fixing it for production models. So we recently set off for Bundy Hill Off-Road Park in Jerome, Michigan, in a production-spec Grand Cherokee Trailhawk to check their work and get a better idea of the overall package. We can report that the Trailhawk's throttle has been fixed for production, landing it properly in Goldilocks territory. In the off-road Mud setting, the throttle is soft and easy to modulate. You can balance this rig with the gas pedal, reaching just past tip-in to steadily prod forward. But the gas pedal doesn't delay when you really need power. Move beyond the initial tip-in, and the engine responds quickly, which is a good thing, as a sluggish throttle is almost as dangerous off-road as one that's too sharp. Rock mode promises even more precise control over the throttle, although our lack of a spotter and a desire to avoid damaging the 700-mile-young Trailhawk kept us from hitting Bundy Hill's rockier sections. The wet, non-snowy weather meant we didn't properly test Snow or Sand mode. This test model was equipped with FCA's popular 3.6-liter V6, but like the rest of the Grand Cherokee range, more power is available from the 3.0-liter EcoDiesel V6 and the 5.7-liter Hemi V8. You don't need them – the 3.6-liter and eight-speed automatic are perfectly fine on the trails. Faced with an incline, the transmission holds its gear without complaint – you don't even need to switch into manual mode. Despite the 4,800-rpm torque peak, the V6's 260 pound-feet arrive early enough that you don't need to strong-arm the throttle. So that's resolution for the pre-production issue. But our time at Bundy Hill exposed a different and ultimately much easier to fix problem for the production model. Late fall in Michigan is not always a good time to go off-road – sub-40-degree temperatures and a steady, depressing drizzle can turn a relatively simple trail into a slippery mess of wet clay. Conditions like these can easily overwhelm an on-road tire like the Goodyear All-Terrain Adventures the Trailhawk uses.
