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 Grand Cherokee Trackhawk First Drive | Crazy. Good.

TAMWORTH, New Hampshire – We're tempted to tell you that the 2018 Jeep Grand Cherokee Trackhawk is ridiculous. It's borderline frightening to think that we now live in a world where anybody with the money and the gumption can stroll into the nearest Jeep dealership and place an order for a 707-horsepower Hemi-powered Grand Cherokee. Let's put this slice of history into perspective. The original Jeep, the one used by the military, boasted 60 horsepower from the Go Devil four-cylinder engine under the hood. The most powerful version of the muscle car-era 426-cubic-inch Hemi was factory-rated at 425 hp. And even if that legendary powerplant was underrated from the factory, the Grand Cherokee Trackhawk still obliterates it by a couple hundred horses. In an SUV. Seven-hundred-horsepower sport utility vehicle doesn't exactly roll off the tongue, does it? And conventional wisdom says it shouldn't. But we're here to tell you otherwise. After driving the Trackhawk in and around the streets of Portland, Maine, and taking it to Club Motorsports in New Hampshire, we're convinced that Jeep and SRT engineers have managed to defy physics and reason. The Trackhawk isn't just fast, it's also manageable. Subdued, even – at least when you want it to be. Put the hammer down, summon the nearly demonic power of supercharged combustion, and all hell breaks loose. But the tires don't. With launch control engaged and with the programmable engine speed properly chosen, the all-wheel-drive Trackhawk rockets to 60 miles per hour in just 3.5 seconds, over and over and over again. No drama, no wheelspin, just g-force, pressing you and four close friends into the backs of your seats. It's addictive, and the only penalty is single-digit fuel mileage. But we'll wager a guess that anyone shopping for a Trackhawk isn't much concerned about its drinking problem. The only proper way to experience the Trackhawk's acceleration is from inside. But, to give you an idea of its speed and power, check out the videos below. Stick around for a walkaround both inside and out, and for a look under the hood. Jeep had to make a few small changes to the well-known 6.2-liter supercharged Hellcat V8 engine to shoehorn it under the hood of a Grand Cherokee. The oil pan is reshaped and baffled, the intercooler is modified, and the exhaust manifolds are new. The result is a reduction in torque from 650 pound-feet in Dodge Hellcat models to 645 in the Jeep, but we wouldn't worry about that.

2017 Jeep Model Year Preview and Updates

This will be a huge year for Jeep, with the introduction of an all-new compact Compass crossover - pictured above - taking place in November, 2016 at the Los Angeles Auto Show, and the pending introduction of an all-new Wrangler later in the calendar year. Not all Jeep products are Trail Rated, but those models will get the most marketing attention. CHEROKEE: Jeep's midsize crossover receives a mild refresh as it makes its way from assembly in Toledo, Ohio to a retooled plant in Belvidere, Illinois. Most of the Jeep feature updates are directed to the Cherokee Trailhawk, which receives heated/ventilated front seats covered in Nappa leather, a power eight-way driver's seat, Keyless Entry 'n Go and remote start. An upscale Overland trim adds a Heavy Duty Protection Group and Trailer Tow Prep packages. COMPASS: This all-new 'global' compact SUV will be built and sold around the world. Sitting atop FCA's 'small wide 4X4 platform' (like the newish Renegade), the Compass offers a more substantial presence than the smaller Renegade, while promising to be more maneuverable and responsive – at least with comparable four-cylinder power – than the larger Cherokee. Expect the 2018 Compass to arrive in Jeep showrooms by midyear. GRAND CHEROKEE: The Trailhawk, with up to eleven inches of ground clearance, best-in-class towing and a crawl ratio of 44.1:1, is revived, three new exterior colors are added, and the front fascia on all '17 Grand Cherokees is tweaked. For those wishing to reach the Summit, Jeep's Grand(est) Cherokee offers an upgraded interior, 'high' style. PATRIOT: At the tail end of its product cycle, the Patriot is unchanged. Of continued interest to Jeep enthusiasts is its genuine off-road credibility, propelled by the Patriot's Freedom Drive II off-road package. This includes a second-generation CVT2L (CVT transmission with low range), skid plates and a more offroad-centric wheel/tire combination. RENEGADE: If you're a traditional Jeep enthusiast you'll wonder why anyone would consider a Renegade. And if you're a new Jeep enthusiast you'll wonder why anyone would disregard this popular Jeep introduction. Still new to the showroom, in 2017 Jeep introduces two new trims: the offroad-oriented Deserthawk and attitude-oriented Altitude.
