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.

FCA recalls 2 million Ram trucks over airbag issues

Airbag issues have prompted Fiat Chrysler Automobiles to issue another pair of recalls. The two separate issues both affect Ram pickups, one campaign stemming from oversensitive sensors, the other from a wiring harness. Between them, the problems affect an estimated combined total of some 2 million units. The first recall affects 2013-15 Ram 1500, 2500, and 3500 trucks, specifically four-door models, manufactured between June 20, 2012, and January 26, 2015. The calibration of the side impact sensor in those affected units may to be too sensitive. As a result, if the door is slammed too hard, the side-curtain airbag and seatbelt pre-tensioner may inadvertently activate. FCA reports that this issue affects an estimated 667,406 units in the United States, plus 153,011 in Canada, a further 8,272 in Mexico, and another 14,847 in markets outside of North America, amounting (in Chrysler's estimation) to less than 0.005 percent of those vehicles produced. The automaker says it is aware of two minor injuries (but no accidents) that may have resulted from the glitch, and is taking action to have the Occupant Restraint Control module recalibrated in the affected units. The second issue also affects Ram pickups, including 1500, 2500, 3500, 4500, and 5500-series models from the 2012 to 2014 model years, built between January 18, 2011, and October 7, 2014, and fitted with the optional Electronic Vehicle Information Center. The problem here stems from a wiring harness in the steering wheel that may rub against a retainer spring in the air bag control module, which in turn could cause an electrical short and deploy the driver's side air bag unexpectedly. In the United States alone, the issue is estimated to affect 1,060,531 units, which will need to be inspected and, where necessary, have their steering wheel wiring harnesses secured, with protective caps added to the ends of the airbag retainer spring. These do not represent the first issues we've seen from Fiat Chrysler in recent days. The automaker recently issued a recall for approximately 1.4 million vehicles to have their Uconnect software updated to prevent hacking. A few days ago it also announced a recall for 350,000 Dodge Journey (and Fiat Freemont) crossovers to secure loose engine covers. And the National Highway Traffic Safety Administration is expected to issue Fiat Chrysler Automobiles a $105-million fine for mishandling other recent recalls and safety issues.

Car Club USA: Louisiana Mudfest

There's nothing quite like mudding. Big tires, huge power, and crazy-wild gearheads that like to throw down on a mud pit almost as much as a thirty rack of Coors. In the latest, and some might argue greatest yet episode of Car Club USA, we head to Louisiana to throw some dirt at Mudfest. As Louisiana's one and only Mouth of the South puts it, "If you don't mud ride... go to Texas I guess." Joining The Mouth and friendly rivals The Most Hated Mud Sluts, we dive in. Beyond the obvious V8 blasting and tractor-tire spinning, those who know best describe Mudfest as, "Good cooking, good friends, good fun, and a lot of partying." It's a motorsport spectacle unlike any you're likely to find up North or out West, though no less impressive to behold. Follow along with the fun, the impromptu drag racing, the trash talking, and the mechanical madness. And find out why, at Mudfest, "if we don't tear it up, we ain't done it right."
