2015 Dodge Challenger SRT Hellcat revving is sonic bacon

This is the Dodge Challenger SRT Hellcat, and we're sure that by now, you know its stats, including over 600 horsepower from its 6.2-liter, supercharged V8. What, pray tell, does that blown engine sound like, though?
At least judging on the sonic strength of this video, it's very, very dirty. Honestly, it sounds unlike anything that's come out of the Chrysler Group in a long time, if ever. It's loud, almost brutally so, with a bark that few road-going V8s can match.
Of course, you should be the final judge here. Take a look and a listen at the two videos below, one of which comes from our friends at Cars.com that provides a nice look under the hood, and then let us know what you think of the Hellcat's singing voice in Comments.

Dodge recalling 2k SRT Hellcat Challengers and Chargers for fuel leak

Bad news for fans of the obscene output of the Dodge Hellcat twins, as FCA has announced a voluntary recall of both 707-horsepower variants of the 2015-model-year Charger sedan and Challenger coupe. According to FCA, a total of 2,211 cars are being recalled after a dealer discovered a "possible fuel leak" during a pre-delivery inspection. Despite getting cleared by suppliers, FCA claims its engineers found "improperly installed" hose seals. Owners of affected vehicles will receive notification and be asked to report in for repairs. Of the vehicles affected, the overwhelming majority, 2,012, were sold in the US market. The remainder were sold in Canada (148), Mexico (30) and just 21 outside of North America.

An FCA US dealer alerted the Company to a possible fuel leak following a pre-delivery vehicle inspection. These components had passed the supplier's leak-testing, but FCA US engineers launched an investigation and discovered certain hose seals may have been improperly installed. The Company is unaware of any related injuries, accidents or customer complaints. Affected are model-year 2015 Dodge Challenger SRT coupes and Dodge Charger SRT sedans equipped with 6.2-liter V-8 engines. There are an estimated 2,012 in the U.S.; 148 in Canada; 30 in Mexico and 21 outside the NAFTA region. Affected customers will be notified and advised when they may schedule service.

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.
