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.

Dodge Charger Hellcat hitting 60 in 2.9 seconds on drag radials?

The Dodge boys and their cousins from SRT have shoehorned the same 707-horsepower, 6.2-liter supercharged V8 into both the Dodge Challenger and Charger. The former being a two-door, it's lighter than the latter four-door sedan. So it would stand to reason that the Dodge Challenger SRT Hellcat would be the quicker of the two, right?
Only that's not necessarily proving to be the case. On stock rubber, yes, the coupe beats the sedan: Dodge quotes a 0-60 time of 3.7 seconds for the Charger SRT Hellcat and 3.5 for the Challenger. Same gap across the quarter-mile: 11 seconds flat for the Charger versus 10.8 seconds for the Challenger. But according to recent reports, the story changes when you put both on drag radials.
While visiting Chrysler HQ in Auburn Hills, MI, TorqueNews.com caught wind of performance figures for the Charger Hellcat on drag tires: 0-60 in a mind-blowing 2.9 seconds and a quarter-mile in just 10.7. The latter figure just barely pips the Hellcat-powered Challenger's NHRA-certified figure of 10.8, making the Charger not only the fastest sedan on the market, but also the fastest muscle car. What isn't immediately clear, however, is whether the drag radials in question have any tread on them and are street-legal, or if they're pure slicks confined to a closed strip.
