Jeep mulling power top for next Wrangler

Jeep is hard at work on the next-generation Wrangler, though the truck is still a few years from hitting the trails. The new model will still be aimed at off-roaders, but rumors suggest it will be a little more comfortable than previous versions to appeal to more people.
According to Road and Track, Jeep is developing a power-retractable top as an expensive option for the Wrangler. There is no word if the top in question is a sliding canvas rollback like the ones found on many European vehicles or a full convertible hardtop or softtop, nor do we know whether it would be made available on two- or four-door models. It might be a nice feature for some buyers but would certainly add complexity to a truck already known for its ruggedness. We asked Jeep for confirmation, but Jeep spokesperson Todd Goyer could only remind us that the company "can't comment about future products."
In news that is likely to irk the faithful, R&T reports the next model may also ditch its folding windshield for improved safety and possibly even get rid of its rear-mounted, full-size spare tire. The new Wrangler won't go completely soft, though, and will reportedly still feature removable doors and solid axles.

How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

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.
