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.

2021 Ram 1500 TRX Suspension Deep Dive | Underbelly of the beast

I think we can all agree that we have been waiting for a gonzo full-size truck like the 2021 Ram 1500 TRX for a long time. After all, it has been over a decade since the Ford F-150 Raptor came out, and it was such an immediate hit that I expected its direct competitors to respond much sooner than this. We all knew something was finally brewing in 2016, when the TRX concept was unveiled at the Texas State Fair. I was there, and was among the many who gave the assembled Ram higher-ups an enthusiastic thumbs-up. That’s what they were hoping to see before they greenlit the project. The pace of development being what it is, and with the redesigned, current-generation Ram 1500 a prerequisite that understandably had to come first, itÂ’s no surprise that weÂ’re only seeing it now as a 2021 model. You may be biting your tongue that I overlooked the Tundra TRD Pro or the Chevrolet Silverado Trail Boss, but neither of those comes close to following the formula established by the Raptor: big engine, a much wider stance than the base truck, greatly enhanced suspension travel, huge tires and swollen fenders to cover it all. Only the Raptor and the TRX fit that mold. For now.   Before I got started, I first pointed the TRX up my RTI ramp and measured its Flex Index score. Please excuse the shaded nose; the truck ran farther up than IÂ’d guessed and literally drove out of the picture. But something in my subconscious warned me to keep the garage door open, which was fortuitous because the nose of the Ram ended up inside. The TRX hiked its front wheel 29 and 7/8 inches off the ground before the left rear tire reached the point of lift-off, and that equates to a climb of 87.4 inches up the deck of my ramp. Divide that by the TRXÂ’s wheelbase of 145.1 inches, multiply by 1,000, and you arrive at a Flex Index score of 602 points. It could have been a few points higher, I think, if I could have straightened out the steering a bit better. But the high-grip cheese grater surface of my ramp was firmly dug in and having none of it. This is an extremely good score for a full-size crew cab pickup. LetÂ’s take a closer look at what made that possible.   The track width of the TRXÂ’s double wishbone front-suspension is a full 6 inches broader than a regular Ram 1500, and you are looking at the parts that are responsible. The lower wishbone (yellow arrow), the upper control arm (green) and the steering knuckle (red) conspire to add 3 inches per side to the TRXÂ’s stance.

Power Wagon train: Exploring the Mojave Road

If you're in Vegas with free time and keys to a Power Wagon, taking an interstate home seems pointless when there's a 135-mile desert trail an hour away, an ideal opportunity to live with – and in – this off-roading Ram pickup for three days. So with friends schlepping camping gear to a rendezvous, this test/history lesson was on. The Road The Mojave Road most closely echoes the path 19 th century westbound settlers and eastbound government supply teams followed between the Colorado River near the AZ/CA/NV junction and Barstow en route to Los Angeles. This 35 th parallel route based on Indian trails has also been called the Old Spanish Trail, Old Government Road (how it appears on many navigation system maps), and the Mohave Road. It was preferred for having more temperate weather and reliable water than routes further south. Desert travel particularly was all about water at regular intervals. Much of the Mojave Road is under National Park Service purview in the 1.6-million-acre Mojave National Preserve, encompassing a big chunk of southeastern California. Nestled between two interstates, there are paved access roads to north and south, so you needn't run the entire distance if only a few areas interest you. It is home to geologic formations from mountains to lava beds and tubes, Joshua trees, and after rains like this winter, beautiful wildflower blooms. You'll see old mines and rail lines, and hear the "singing" sand dunes at Kelso (which I'd categorize as more of a monk's chant). We saw birds of prey, wild burros, lizards, and rabbits, and heard or saw evidence of coyotes, cows, and roadrunners. All the while figuring a rattlesnake could be behind any bush. The plan was to enjoy the mesquite scents and make a few stops (the Rock House, Mojave Mailbox) but otherwise make a non-committal east-to-west camping trip of it. Do as much or little as you like, though the NPS does remind you the desert can be an inhospitable place. Cell service is hit-or-miss, and they specifically recommend against relying solely on automotive GPS navigation. Lower elevations average triple-digit highs four months of the year while upper elevations get snow; in February the temperature at our 2,800-foot campsite dropped to freezing while days were sunny and moderate. If the entire road is open, it's about 135 miles from the river to western end, but in February expect portions to be closed, potentially making it many miles longer.
