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.

Side-X-Sides: The next Wrangler?

The Jeep Wrangler has a huge following, but I've long thought that it is ripe for plucking. And if rumors of a neo-Bronco prove to be true, it sounds like Ford may agree. If a new Bronco does pan out, I hope it's small like the original Bronco, and not a huge F-150-based vehicle. To be a true Wrangler-fighter it has to be small and nimble. Here's another option How about developing a slightly larger, but street-legal version of the popular side-x-sides which are so popular with hunters, fishermen, farmers and anyone outdoors-oriented? This, to me, seems to be the next logical evolution of these side-x-sides. Currently side-x-sides have to be either trailered or stuffed into the back a of a pickup to wherever they're going to be used. Offering a street-legal off-roader solves that problem. There's no shortage of side-x-side makers out there. Any one of them could engineer and market such a vehicle, should they decide to. Plus there are plenty of dealer outlets, although Honda is the only one that currently sells cars, etc.; so they could have an edge in the selling and servicing aspects of such a vehicle. That said, I'm not sure Honda would want to sell such a vehicle in their car outlets. It may be better suited to their dealers that sell motorcycles, ATVs, watercraft, etc., as that outdoorsman type of customer already frequents those dealers. Then again, if the new Ridgeline proves popular, such a vehicle could offer something much more capable and sporting to that customer who is looking for something more extreme. The Wrangler has its fans, and they love it just as it stands. In fact Wrangler fans would reject any drastic engineering changes to their beloved off-roaders Side-x-sides, on the other hand, offer a completely different take on how to engineer a small but serious off-roader. Both are valid approaches. Currently the only thing missing are street-legal side-x-sides that go head-to-head against the Wrangler. Having more purchase options available is always a good thing; seems like a no-brainer to me. Image Credit: Honda Jeep Off-Road Vehicles open road

2019 Jeep Cherokee First Drive Review | Still the most truck-like crossover SUV

The history of the SUV has been one of ever-increasing refinement, and that arc bends towards carlike forms. It's a trend that even the hardiest of nameplates has succumbed to, including the venerable Cherokee, which for 2014, moved from the solid-axle brick of yore to the shark-nosed, independently suspended crossover of modern-day. That wasn't necessarily a bad thing. We found it to be quite a competitive machine at the time, and one that was plenty capable. But time marches on, and five model years later, Jeep has updated the Cherokee. The polarizing shark nose has been toned down, with all the headlight elements integrated into single units on either side. The hatchback has been revised and now sports a cutout for the license plate. Besides improving the looks at the back, Jeep says it allowed them to expand the rear cargo area to 25.8 cubic feet, an increase of 1.2 cubes, because moving the license plate space allowed them to pull the latch assembly farther out. It should be noted, though, that the Cherokee still doesn't have as much cargo capacity as the new 27.2-cubic-foot Compass. Besides the cosmetic changes, the new Cherokee gets a new engine, a 2.0-liter turbocharged four-cylinder good for 270 horsepower and 295 pound-feet of torque that shares commonality with the Jeep Wrangler and Alfa Romeo Giulia engines. However, it lacks the mild hybrid technology of the Wrangler because of space issues, and it has a cylinder head with two camshafts rather than the Alfa's single-overhead cam design. In addition to the new 2.0-liter turbocharged engine, the Cherokee's old naturally aspirated engines, a 2.4-liter four-cylinder (180 hp, 170 lb-ft) and a 3.2-liter V6 (271 hp, 239 lb-ft), carryover unchanged except for the addition of standard engine start-stop functionality. The question is, can mild changes to the Cherokee keep it competitive in a segment where several rivals have been completely redesigned? In terms of capability, the answer is a resounding, "yes," particularly for the Trailhawk, which in turbocharged guise, has even shorter gearing for its low-range four-wheel-drive setting than before at 51.2:1. Like the previous model, the Trailhawk includes different front and rear bumpers for improved clearance and approach and departure angles. It features a set of skid plates and gets a steel oil pan for protection from obstacles, and the rear axle can be locked for additional traction.
