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.

It ain't easy keeping a Hellcat steady at 170 mph on ice

The Dodge Challenger SRT Hellcat you see hit the ice at Arsunda Speed Weekend in Sweden, over two hours north of Stockholm. It's said to be bone stock, save for the studded tires that help it grip on ice. But it apparently takes more than some steel studs and a lead foot to keep it pointed the right way. Just look at how much driver Alx Danielsson has to saw at the wheel to keep the Hellcat from veering off course. Fortunately he seems to have the chops to do so, being not only a native of Sweden (and therefor imbued from birth with otherworldly abilities to drive on ice) but also having won the highly competitive Formula Renault 3.5 Series championship back in 2006. In the end Danielsson hit a top speed in excess of 170 miles per hour, touted as some sort of record, however unofficial (and specific to Dodge Challengers). That's a fair bit shy of the 205 mph that Bentley achieved in the Continental Supersports, but while that model had slightly less power than the Hellcat, it did have the benefit of all-wheel drive – something that could make all the difference in these kinds of slippery conditions.

The Dodge Demon is coming, an evil mutation of the Challenger SRT Hellcat

If there's one thing we'll take more of, it's Hellcat. Dodge's 707-horsepower supercharged V8 is a shining star of muscle car ideals. A panacea to the cylinder-count and displacement atrophy. And according to Dodge's new website, www.ifyouknowyouknow.com, a even crazier version of the Challenger SRT Hellcat is on the way. It's called the Dodge Demon. The website features a series of videos that reveal more and more details of the upcoming car. As of this writing, only the first teaser is available, title cage (and also seen above). The final video, and full reveal, of the car, coincides with the dates for the 2017 New York Auto Show. Details are scant at this point. The video, and the press release statement from FCA passenger car chief Tim Kuniskis, point to quarter-mile performance as the Demon's sole purpose in life. Said Kuniskis, "The Dodge Challenger SRT Demon is conceived, designed and engineered for a subculture of enthusiasts who know that a tenth is a car and a half second is your reputation." Whether that means an all-wheel-drive Hellcat, more power, or both remains to be seen. Stay tuned. Related Video: This content is hosted by a third party.
