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.

2018 Dodge Demon comes with a factory tune for race gas

We knew the Dodge Demon was going to make a lot of power, but the ongoing question has been how much. We've seen estimates of between 757 and 1,121, but those have simply been guesses based on the numbers found in promo photos. However, if we had to put our bets on a horsepower rating, we'll probably go with the higher estimates because the Demon can run on race gas. Yes, the latest teaser for the Demon reveals that it will come with a factory tune optimized for race gas, which is rated at 100 octane or higher. Running such high octane, in combination with its heavy-duty intake cooling, means the Demon can handle absurd amounts of boost and advanced timing without running the risk of dangerous pre-ignition or detonation. Of course this also means the Demon should be capable of astonishing power with the high-octane calibration. The tune will be included in the Demon crate on a separate engine computer that the owner can swap out when he or she is ready to race. In addition to the computer, the center stack also has a button to activate the high-octane mode. A pair of fuel pumps and larger injectors also ensure the engine gets plenty of that sweet racing fuel. When not running the high-octane tune, the Demon runs on your average premium gasoline. Also, in case you accidentally run premium gas with the high-octane mode activated, the car will automatically switch to the default tune if engine knock is detected. You can get a peek at the system in the video above, and be on the lookout for a bonus video tomorrow. The full reveal will be next week on April 11 at the New York auto show. Related Video:

Takata airbag recall claims 209k Chrysler, Dodge vehicles

Chrysler is expanding the scope of its front passenger side Takata airbag inflator recall yet again to include 139,115 additional vehicles for a total of 208,783 units now needing these parts replaced. The latest campaign affects the passenger side inflators of the 2003-2005 Dodge Ram 1500, 2003-2005 Dodge Ram 2500, 2003-2005 Dodge Ram 3500, 2004-2005 Durango; 2005 Dakota pickup; 2005 Dodge Magnum and 2005 Chrysler 300 (pictured above), 300C and SRT8. It's limited to vehicles purchased or ever registered in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, Texas and the territories of American Samoa, Guam, Puerto Rico, Saipan and the US Virgin Islands. The company expects owners to be notified by February 8. The automaker just expanded the replacement campaign last week to include passenger side inflators in 149,150 pickups from the 2003 model year. However, the parts are not the same. Chrysler says this recall is for the PSPI family of components versus SPI for the last one. The company is also not aware of any injuries or accidents in its vehicles from these potentially faulty inflators, and lab testing of 600 of them finds no issues. Despite this, Chrysler is repairing these models at the request of the National Highway Traffic Safety Administration. Scroll down to read the company's full announcement of the initiative. Statement: Air-bag Inflator (Regional Field Action Expansion) December 12, 2014 , Auburn Hills, Mich. - Chrysler Group is expanding an ongoing regional field action with a recall to replace front passenger-side air-bag inflators in an estimated 208,783 older-model vehicles originally purchased or ever registered in seven U.S. states and five territories. The vehicles are equipped with front passenger-side air-bag inflators from a product family code-named "PSPI." Chrysler Group is unaware of any injuries or accidents involving PSPI inflators of the type covered by this campaign, nor has a Chrysler Group investigation identified a defect in these components. Further, laboratory tests on nearly 600 such inflators did not result in any failures. The inflators affected by this campaign differ in design and construction from PSPI inflators used by other auto makers. They also benefited from a more robust manufacturing process. However, at the request of the National Highway Traffic Safety Administration (NHTSA), Chrysler Group is expanding its replacement action beyond its original scope of Florida, Hawaii, Puerto Rico and the U.S.
