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.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
