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.

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.
