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.

Dodge Charger SRT Hellcat in the works

In Autoblog's recent First Drive of the 2015 Challenger SRT with the 707-horsepower Hellcat V8 we found its engine to be as brutally powerful as the numbers would suggest, even if it wasn't the best handler. However, the muscle-car-styling just isn't right for some buyers that need four doors and proper rear seats to haul around the family. It appears that Dodge has their backs, though, because the Hellcat is very likely on its way into the Charger in the near future. Imagine the looks on your passengers' faces when you stomp down on the throttle.
According to Road and Track, when Dodge submitted the Hellcat for engine power certification to the Society of Automotive Engineers, the company included the Charger on the paperwork. That showed that the automaker wanted the engine checked out for the sedan, too. R&T reckons the 707-hp Charger would hit the road about a year from now, clearing the Challenger for a year of exclusivity with the powerplant.
When the Charger SRT Hellcat does hit the road, it may carry a very special accolade. Assuming nothing beats it in the meantime, it might be the world's highest horsepower production sedan. Think on that for a second. Even a Mercedes S65 AMG only has 621 horsepower, though a good bit more torque at 738 pound-feet to the Dodge's 650 lb-ft. So while the beastly engine is getting put into other models, where else would you like to see it? The Ram? Grand Cherokee? Let us know in Comments.

Dodge CEO and Gas Monkey Garage dissect the 10-second Challenger Hellcat

So far, whenever we've seen the 2015 Dodge Challenger SRT with its 707-horsepower, supercharged Hellcat V8, the muscle car has been smoking its tires. Dodge is finally proving that the SRT can do more than ruin perfectly good sets of rubber, though. In it's latest video, company CEO Tim Kuniskis hands the Hellcat off to the guys from Gas Monkey Garage to show how quickly the automaker's most powerful model can make it down the drag strip.
Of course, the only fitting contender to race against Dodge's latest top muscle car is its grandpa - a Hemi-powered 1971 Challenger, in this case. Before getting to the main event, the hosts also show off some of the SRT's unique features like the blanks in the grille that feed the intercoolers. We'll go ahead and spoil that the Hellcat makes its pass in the 10-second range, and the video admits the tires on the production version would take just a touch longer to cover the quarter-mile. However, you have to watch film to see just how quick it actually goes. Scroll down to see a classic example of American muscle drag racing against its modern legacy.
