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.

The Dodge Demon was developed under a cloud of smoke

The Dodge Demon needs no introduction. The car is so full of superlatives that most of it sounds unbelievable until you see and hear it in action. The car was revealed after months of teasers and cryptic messages, but the public weren't the only ones in the dark. From the start, the Demon's development was a closely guarded secret. There were even some within SRT that didn't know about the project. The people behind the car went through a lot of effort to keep it that way. At an event covering the finer details of the Demon's supercharged 6.2-liter V8, Dodge CEO Tim Kuniskis and SRT Powertrain Director Chris Cowland spoke about the smoke and mirrors used to hide the Demon's development. Work on the car progressed for nearly two years before it was made public, with just a small team having full access to the project. Numbers were altered. Secret meetings were held. SRT engineers worked nights and weekends while parts suppliers were given as little information as possible to move progress forward. Preliminary work on the Demon began in April of 2015, not long after the standard Hellcat hit the streets. The goal wasn't to create a faster Hellcat. Kuniskis said that would have been easy. They wanted a single-minded vehicle that could also be driven on the road. It's the same mindset that brought about the Dodge Viper ACR. Dodge wanted a car that could sell the brand to both enthusiasts and non-enthusiasts alike. 840 horsepower is going to raise anyone's eyebrows, including the Camry owner parked down the street. While preliminary work started in April, the final greenlight wasn't given until September. The project was originally going to revive the American Drag Racer, or ADR, name. When we saw the first hints of the Demon last fall, we labeled the spy photo above the Dodge Challenger ADR. It was set to have 10-percent more power and 20-percent more launch force than the already gut-punching Hellcat. It was also only going to have a quarter-mile time in the 10s, just slightly quicker than the Hellcat. Somewhere along the line, the team realized that the ADR wasn't enough. It was just going to be a Hellcat plus, and that wasn't exciting. The main goal was changed: 9s with light. Translated, that means a 9-second quarter mile with light under the tires (read: a wheelie). From that point forward, everything about the Demon's development, from power to suspension to weight, would be done in pursuit of that goal.

Happy Halloween, cats and kittens!

Happy Halloween, everybody. There's no real Hellcat news in this post. No growl of the second-scariest Dodge Challenger SRT's 707-horsepower engine, no shriek of its supercharger. Just a Hellcat on a photo shoot. A little eye candy on Halloween. In a graveyard. With a black cat. (No cats were doomed to hell in the making of this feature.) But a Hellcat is a good kind of scary, so here are some of our previous galleries. And may a Hellcat cross your path soon. View 18 Photos View 17 Photos View 80 Photos Related Video:
