Fiat-Chrysler shows its SEMA lineup

Fiat Chrysler Automobiles already previewed its 2014 SEMA show lineup with some slick renders. Now, the automaker has finally showed us the actual cars, and among the group there are definitely some that stand out more than others.
Dodge is really showing off its muscle at this year's show with four concepts that all pump up the power of the brand's models. Perhaps most interesting among them is the Challenger T/A Concept (pictured above) in striking Sublime Green and matte black. It's meant to resemble the classic Trans Am racer from the '70s. Under the hood is a 6.4-liter V8, and to fit the vintage style there's a pistol-grip gearshift inside.
The Charger R/T also gets some attention with the Mopar concept that shows off what FCA's aftermarket performance arm can do. Mods include an updated body kit, cold-air intake for the 5.7-liter V8 and a coil-over suspension kit. Beyond that, the Dart R/T Concept looks a lot meaner with a black hood with duct work that leads straight to the air intake. The rest of the compact sedan is dolled up in O-So-Orange paint and is fitted with upgrades to improve handling like a coil-over suspension and big brake kit from the Mopar catalog.

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.

Chrysler recalls 468,700 Jeep Grand Cherokees, Commanders over rollaway risk

Chrysler has issued a recall covering a combined 469,000 units of the 2005-2010 Jeep Grand Cherokee and the 2006-2010 Jeep Commander (inset). Of that number, 295,000 are in the US, roughly 33,000 in Canada and Mexico and the remainder in other markets. It seems an electrical fault in the transfer case can allow the affected SUVs to shift into neutral on their own, while an Associated Press report says that Chrysler had "found cracks in a circuit board that turns the four-wheel-drive system on and off." The issue was discovered when an owner started his car remotely and it rolled away.
Chrysler is expected to begin notifying owners in June 2013, who can then take their cars to dealers. The dealer will reflash the final drive controller free of charge. There's a bulletin from the National Highway Traffic Safety Administration below with more information.
