How to turn a Dodge airport tug into a trail slayer

Sometimes, having a ton of fun requires takes a ton of work. Just nine days before the so-called Ultimate Adventure 2014, the folks behind 4-Wheel & Off-Road had 40 tasks to complete in order to turn the ratty truck pictured above into a machine that could excel on treacherous off-road trails while still being able to handle highway jaunts. Much of process behind the build was chronicled on the latest episode of Dirt Every Day.
The team's vehicle started life as a 1990 Dodge tug truck that spent part of its life hauling around airplanes. The builders hung on to the Cummins six-cylinder diesel, but they tossed out practically everything else for the project, with some seriously heavy-duty replacement parts for the transmission, transfer case, axles and a whole lot more. The process was certainly a ton of work, but the end result looks like a fantastic crawler.
Sure, it might have been easier to bring a truck that was already prepared, but where would the fun in that have been? Stay tuned until the end of the video for a few glimpses of the completed Dodge and peek at some of the punishment it goes through.

Stellantis reveals STLA Large platform with EV and ICE support

Hot on the heels of a Jeep Wagoneer S teaser and photos of the prototype next-generation Dodge Charger (or Challenger), comes a reveal and details of what will likely underpin both of them: the STLA Large platform. It's one of multiple Stellantis flexible architectures that will be the basis of its upcoming electric cars, and apparently internal combustion ones, too. Stellantis says the STLA Large platform will be for D- and E-segment cars, crossovers and SUVs. In other words, it will be for midsize and large vehicles. For reference, lengths supported will be from 187.6 to 201.8 inches, and width will range from 74.7 to 79.9 inches. It will be highly flexible, too, with Stellantis claiming significant amounts of adjustability in overhangs, wheelbase, suspension placement and powertrain arrangement. The powertrain flexibility is quite impressive. Front-, rear- and all-wheel-drive layouts will be supported. Single- and dual-motor layouts will be on offer. Internal combustion will be available, too, either on its own or as a hybrid. Apparently engines can be fitted either longitudinally or transversely, too. Battery packs with between 85 and 118 kWh of capacity will be offered, with Stellantis claiming that sedan-style vehicles could have a range of up to 500 miles. The packs will also be available in 400- and 800-volt designs. Stellantis noted also that the platform can "easily accept future energy storage technologies when they reach production readiness." This seems to hint that the company is looking at different battery chemistries and maybe even solid-state batteries that could be added more easily in the future. Furthermore, the platform is designed to handle impressive output. Stellantis says that some models on the platform will have 0-to-62 mph times in the 2-second range. Limited-slip differentials for improved power delivery and wheel-end disconnects for reduced mechanical drag are also on the table for this platform. All of these details fit well with the information previously given for the concept Dodge Charger Daytona Banshee and Jeep Wagoneer S. The former was previewed with both battery voltage architectures and a wide range of electric powertrains with between 456 and 670 horsepower depending on specification and upgrades. And that's just for the 400-volt system; the 800-volt option wasn't detailed. We've also seen photos of the Charger chassis seemingly with provisions for gas engines, likely versions of the Hurricane I6.

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.
