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.

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.

Why the Charger Hellcat can't be ordered with a manual transmission

Fans of truly irreverent amounts of horsepower will find lots to love in the form of the 2015 Dodge Challenger and Charger Hellcat models. Both of them send 707 ridiculous horsepower to the rear wheels; the only question is whether you want your absurdity delivered with two or four doors. Oh, and whether or not you want the option of a manual transmission.
If you prefer rowing your own gears, the choice is made for you; there is no manual gearbox option available on the Charger Hellcat, or any Charger model at all, for that matter. Wonder why? Well, besides the fact that almost nobody - sorry, clutch fans, but it's true - would choose to buy a Charger with a manual transmission, that is? The answer, according to an industry insider in a post written on Jalopnik's Opposite Lock forum, is the floorpan.
It's probably not a surprise to most of our readers that the Dodge Challenger and Charger share a large portion of their chassis structure, which is codenamed LX at Chrysler, but there are still some significant differences under the skin due to the shorter wheelbase and two-door coupe bodyshell of the Challenger, as opposed to the sedan shape of the Charger. One of the differences is the floorpan, the huge chunk of sheetmetal that makes up the floor of the car and props up such essential items as the car's seats.
