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.

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.

Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.
