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 says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.

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.
