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.

Best-selling vehicles by state

America loves trucks. According to Edmunds, which has tracked the best-selling vehicles by state based on new vehicle registrations, 40 out of 50 U.S. states’ best-selling vehicle is a pickup. Most often, thatÂ’s the Ford F-Series, but occasional Chevy, Ram and even Toyota top the lists. Here, weÂ’ve compiled the best-selling vehicles by state, including the four runners-up for each state. Interestingly enough, only one EV shows up in a stateÂ’s top five (Tesla Model 3 in California). Read on below to see whatÂ’s most popular in your state.

The 6.2-liter supercharged V8 supplies 650 pound-feet of torque to all four wheels that lets it power out of mud and muck by aggressively flinging it skyward as though it has a vendetta against both the sky above and Earth below. This sort of driving is best done in Mud/Sand mode, as it sets the four-wheel-drive system, throttle response, transmission, suspension and steering into their ideal settings to have the most fun in the slick stuff. It works as advertised. “Going 0-60 mph in 4.5 seconds in a truck so large is already a mind-altering experience, but having the traction and ability to properly launch off-road is where the TRX truly sets itself apart. Those 35-inch Goodyear Wrangler Territory all-terrain tires, developed specifically for the TRX, dig into the mud and dirt, shooting you forward with far less scrambling and scrapping for purchase than youÂ’d expect from such a sloppy surface. The Dana 60 solid rear axle, axle-hop damper and electronic limited-slip differential that Ram claims help those launches are all putting in the work that needs to be done. No matter the terrain, the TRX digs in, growls and shoots where you point it. If youÂ’d rather move sideways, a quick stab of the traction control button relaxes the truck's nannies to do just that. “The suspension is just as hardcore with the Bilstein Black Hawk e2 adaptive dampers and their remote reservoirs making this 6,396-pound lead weight of a truck more agile than it should be, yet forgiving at the same time. Its damping characteristics donÂ’t provide the same pillowy and graceful off-road ride as, say, the Multimatic dampers on the much lighter Colorado ZR2 do, but thatÂ’s comparing apples to oranges on the weight scale.
