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 is more expensive than the Dodge Demon

Jeep has finally released pricing for its crazy, all-wheel-drive, Hellcat-powered Grand Cherokee, and it's seriously expensive. It starts at $86,995. That's a full $2,000 more than the limited-production, 840-horsepower Dodge Challenger SRT Demon. For 140 fewer horses, and a quarter-mile time that's 2seconds slower (11.6 seconds vs. 9.6), you'll spend more money. Then again, the Grand Cherokee can do things the Demon and the Hellcats can't. It's got more space than any of them, meaning you can carry quite a bit more. It's capable of towing up to 7,200 pounds of stuff. It also has all-wheel drive, which means you have a little extra traction in bad weather, and you have the opportunity to do spectacular four-wheel burnouts. And of course, the Trackhawk is still fast and capable by any measure. It's only a tenth of a second slower to 60 mph than the Challenger Hellcat Widebody. It also comes with massive Brembo brakes, with the largest front rotors fitted to a Jeep, to haul it down from 60 mph in a claimed 114 feet. Each corner features 295-mm tires that Jeep claims let the Trackhawk generate 0.88g circling a skid pad. If the Trackhawk sounds like just the absurd performance machine you've been waiting for, you'll be able to put your order in soon. Dealers will accept orders starting Aug. 10, and the vehicles will start arriving at dealer lots toward the end of the year.

2018 Jeep Wrangler JL spotted playing offroad in the sand dunes

The videos above and below, among other things, highlight some of the reasons why it's so terribly difficult for Jeep to introduce a new Wrangler. Needless to say, the ute has got to work offroad. Not only that, but the engineers need to make sure the vehicle is at least semi-content on the road and in the emissions and safety labs, and they have to make sure it pleases the diehards by keeping vestigial bits like external hood latches. Oh, and it can't be priced out of the reach of the average car buyer. That's a tall order. Nevertheless, we're pleased to see that Jeep is taking its offroad testing seriously. These videos were reportedly shot at the Silver Lake Sand Dunes near Lake Michigan. You'll see some splashing through puddles, some steady-state medium-speed cruising, and even some Hazzard-style fishtailing. And you can rest assured that the Toledoans at Jeep have been busy testing their latest Wrangler in other off-road scenarios, like rock crawling at the Rubicon Trail. These three clips are short, and it's difficult to draw conclusions on the suspension action since we can't really tell how flat or bumpy the terrain may be. Still, they're fun to watch and important to Jeep fans. We expect to see plenty more spy footage of the 2018 Wrangler before its likely debut at the LA Auto Show later this year.
