Highway To Hellcat: Dallas to Vegas with 2,000 HP

Fort Davis, TX. Early November. Late Sunday afternoon. The 1,200 residents of this small town are using their day of rest to quietly enjoy the breeze rolling off the hills. There's an older couple walking down the street, holding hands. A young lady working at a general store, where milkshakes and antacids are purchased at the same counter. It's a peaceful, quaint scene, right down to the tumbleweed rolling across the street and the rickety wooden porches outside the old storefronts. I hit the throttle of the 2015 Dodge Charger SRT Hellcat while turning left onto the road leading toward the town square, sending the sedan's rear end swinging to the right with a few puffs of rubbery smoke. I coast down to the 25-mile-per-hour speed limit and spot the line of Challengers, Chargers, and Vipers in my rear-view mirror, the drivers all mimicking my quick jolt of enthusiasm before pulling up the reigns on their V8s and V10s and idling into Fort Davis. Our posse would roll some 5,000 horsepower of pure American muscle into that small Texas town that day. It was only the first stop on an epic journey that would take us from Dallas to Las Vegas, on a winding route down toward El Paso, up through New Mexico, Arizona, and finally north into Nevada, ending at the ritzy Palazzo casino and hotel on the Vegas strip. It was an opportunity to see parts of America I never knew existed, and a chance to bond with some American cars that until recently, I sort of failed to understand. And most importantly it was an opportunity to drive really, really hard. Charging Through Texas Unless you've driven across it, it's hard to understand the massive space that is Texas. In places, scanning 360 degrees of horizon reveals absolutely nothing. Nothing. On its own, driving from Dallas to El Paso covers some 630 miles. Veer south to Fort Davis and you'll add another 70 onto that, not including the 75-mile Davis Mountain Scenic Loop where I found bliss behind the wheel of this insanely powerful sedan. I always expected to like the Charger Hellcat – comfortable seating for four (five in a pinch), equipped with the latest tech, wrapped in a stylish yet muscular body, like a quarterback in a tux. And it moves. The supercharged 6.2-liter Hellcat V8 pumps out 707 horsepower and 650 pound-feet of torque, which makes for one quick sedan, especially considering its heft.

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.

Cold start comparison: 2020 Alfa Romeo Giulia Quadrifoglio vs. 2013 Dodge Challenger SRT8

The 2020 Alfa Romeo Giulia Quadrifoglio is a five-seat, compact luxury sport sedan packing 505 horsepower thanks to a 2.9-liter twin-turbocharged V6. My personal 2013 Dodge Challenger SRT8 392 is ... well ... not. It's a full-sized muscle coupe whose iron-block 6.4-liter V8 makes 470 hp in the very traditional way: it's freakin' huge, like everything else about the car.  On paper, these two have nothing in common beyond the fact that they were built by the same multi-national manufacturing entity.  But if paper were the be-all and end-all of automotive rankings, everybody would buy the same car. And we don't, especially as enthusiasts. Whether it's looks or tuning or vague "intangibles" or something as simple as the way a car sounds, we often put a priority on the things that trigger our emotions rather than setting out to simply buy whatever the "best" car is at that particular moment.  So, what do these two have in common? They both sound really, really good. Like looks, sounds are subjective. While a rubric most assuredly exists in the world of marketing (attraction is as much a science as any other human response), we have no way of objectively scoring the beauty of either of these cars, and the same applies to the qualities of the sound waves being emitted through their tail pipes.  But we can measure how loud they are. In fact, there's even an app for that. Dozens, as it turns out. So, I picked one at random that recorded peak loudness levels, and set off to conduct an entirely pointless and only vaguely scientific experiment with the two cars that happened to be in my garage at the same time.  For the test, I opened up a window and cracked the garage door (so as not to inflict carbon monoxide poisoning upon myself in the name of discovery), and then placed my phone on a tripod behind the center of each car's trunk lid. I fired each one up and let the app do the rest. I then placed my GoPro on top of the trunk for each test so that I could review the video afterward for any anomalies.  I started with the Challenger. The 6.4-liter Hemi under the hood of this big coupe is essentially the same lump found under the hood of quite a few Ram pickups, and it has the accessories to prove it. Its starter is loud and distinctive. Almost as loud, it turns out, as the exhaust itself. As its loud pew-pew faded behind the V8's barking cold start, we recorded a peak of 83.7 decibels. In the app's judgment, that's roughly the equivalent of a busy street.
