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.

2015 Dodge Challenger SRT Hellcat with '600-plus horsepower' officially unveiled [w/video]

Dodge has officially unveiled the most powerful vehicle to ever wear the Challenger name - the SRT Hellcat - complete with over 600 horsepower courtesy of a supercharged, 6.2-liter Hemi V8. It will be offered alongside the 485-hp Challenger SRT.
The new, force-induced V8 isn't just the most powerful ever fitted to the Challenger, it's the most powerful eight-cylinder Chrysler Group has ever built. Power figures aren't finalized, so expect to see "over 600 hp" bandied about quite a lot. That fury will be channeled through either a six-speed manual or eight-speed automatic. Yes, over 600 ponies through an eight-speed auto. So far, the only vehicle we know of that delivers more output through that many gears is the as-yet untested Chevrolet Corvette Z06. Sadly, we don't have performance metrics just yet, although if this thing can't crack four seconds to 60 miles per hour, we'll be pretty surprised.
As is the theme nowadays, the 2015 Challenger SRT features a number of driving modes, governing power output, shift speeds for the 8AT, steering effort, traction control settings and suspension settings. There are three pre-programmed options - Default, Sport and Track - and a Custom mode that allows drivers to mix and match to their heart's content.

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.
