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.

Ram Rebel TRX concept is a Hellcat-powered Raptor-fighter

Ford has proven that fast off-road trucks are awesome. Dodge has proven that ridiculously powerful supercharged V8s are awesome. Combining the two would theoretically be even more awesome. The Ram Rebel TRX, which was unveiled at the Texas State Fair, proves that theory. As you may have guessed from the intro, the Rebel TRX uses a supercharged V8. A version of the supercharged 6.2-liter V8 from the Hellcat twins (and, we suspect, the Jeep Grand Cherokee Trackhawk). Because of some new calibrations to make the engine more suited for off-road driving, it doesn't make the full 707 horsepower of the Charger and Challenger. But the TRX engine still cranks out 575 horsepower, which is a full 125 more than the new SVT Raptor. That's enough to propel the mega-sized truck to 100 mph in its off road terrain mode. Power is transferred through an 8-speed automatic transmission to all four wheels. At the back, the Rebel TRX has an electronic locking differential. The TRX also gets an updated version of the Ram's 4x4 Performance Control System featuring Normal, Wet/Snow, Off-road and - best of all - Baja modes. The latter mode is the one that will do triple digits through the desert. Of course a sweet powertrain needs chassis and tire upgrades to round out the package, and the Rebel TRX has plenty of improvements. The standard Ram 1500 frame is unchanged, but bolted to it are custom front control arms, internal bypass shocks at each corner and new springs. The changes bring suspension travel to a full 13 inches all around. It also provides enough space to fit massive 37 x 13.5-inch tires. Ram also added six-piston calipers with 15-inch discs at the front and 14-inch discs at the back. Finally, Ram gave all this heavy duty equipment a big, burly wrapper. The body is a full six-inches wider than the standard 1500 with large composite fenders to cover the aforementioned tires. The truck also has a vented and scooped hood based on the Ram HD. This was necessary to help cool the engine and provide vertical clearance for the supercharger. A large sport bar was added to the back and has provisions for carrying a pair of spare tires, plus an LED light bar on top. The truck also has a big steel skid plate up front, and a sweet integrated side-exit exhaust behind the doors. Inside, the truck gets plenty of leather, suede and carbon fiber. The front seats also have racing harnesses attached to a harness bar that spans the B-pillars.

Chrysler recalling 382k Ram HD diesel pickups, 184k SUVs

Between GM's ignition switches and Takata's airbags, it's been a big year for recalls, but they keep rolling in. The latest comes from Chrysler, which has announced a pair of recalls for certain heavy-duty pickups and SUVs.
The first issue revolves around the 6.7-liter Cummins diesel engine available in the 2010-2014 Ram HD trucks, including 2500 and 3500 series pickups as well as 4500 and 5500 series chassis cabs. In the affected units, "a terminal connector near the fuel heater may be subject to friction-induced corrosion," according to the first of the two announcements from Chrysler below.
The problem could result in overheating and fuel leakage. Chrysler launched its investigation following cases of overheating, none of which actually started a fire, much less an injury or accident. As a precautionary measure, however, Chrysler is instructing service technicians to replace the terminals on an estimated 381,876 Ram units around the world - the vast majority of those (314,704) registered in the US, another 59,432 in Canada, 1,803 in Mexico and 5,937 abroad.
