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.

2013 Ram Heavy Duty seeks to obliterate rivals with claimed 30,000-pound max tow rating

No one can accuse Ram of backing away from the full-size truck arms race. Chrysler has officially dropped the payload details on its 2013 Ram Heavy Duty, and the 3500 now packs a maximum trailer weight of 30,000 pounds. Chew on that number for a moment. That's 15 tons, or the equivalent of a dozen Mazda MX-5 Miata convertibles stacked on a trailer, and it's also a whopping 6,900 pounds more than the closest competitor to the Ram 3500, the Chevrolet Silverado 3500 HD. Ram engineers have cranked the truck's 6.7-liter Cummins turbo-diesel engine to a ludicrous 850 pound-feet of torque, up 50 lb-ft over the 2012 model. "Shock the world" figures, all.
Throw in a stiffer frame, stouter transfer case, beefed-up transmission and brawnier U-joints in the driveline, and you have what Ram is calling "the most capable trucks we've ever built." That includes the Ram 2500, which has seen its towing capacity swell to 18,350 lbs and its Gross Combined Weight Rating jump to 25,000 lbs. Look for the 2013 Ram 3500 HD to bow at the 2013 Detroit Auto Show, and be sure to check out the full press release below for more information.
