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's large, LX-based RWD cars will stick around until 2020

Fiat Chrysler Automobiles plans to stick with the Dodge Challenger, Dodge Charger, and Chrysler 300 until at least 2020, reports Automotive News. The information comes from two unnamed sources and was loosely confirmed by details in the automaker's new labor contract with Unifor, Canada's auto union. The plan, according to two anonymous sources, is to lightly refresh the Challenger, Charger, and 300 until the vehicles make the switch to FCA's new Giorgio platform. The refresh, as Automotive News points out, will happen in 2018. The Giorgio platform currently underpins the Alfa Romeo Giulia and is expected to find its way to two of the three large American vehicles for the 2021 model year. At that time, FCA will discontinue either the Charger or the 300, claim AN's unnamed sources. If one of the vehicles were to go, it would most likely be the 300. The 300's LX platform would be approximately 15 years old in 2020 and the vehicle doesn't draw in as many sales as the Challenger or the Charger. The Charger made the switch from the LX platform in 2010 with the current model utilizing the mildly updated LD platform, while the Challenger recently moved from the LC platform to the LA platform last year. All of those rear-wheel-drive platforms are closely related. Automotive News points out that FCA CEO Sergio Marchionne stated that the new platform could be utilized across various applications in a conference call with analysts last month. The plan, according to the report, is to stretch and widen the Giorgio platform for the next-gen Challenger and Charger. The new platform is also rigid enough to allow the automaker to add a convertible to its lineup, which could lend further credence to rumors of an upcoming Barracuda. Hopefully, the move to the new Giorgio platform doesn't delay the all-wheel-drive Challenger GT AWD or the wide-body, Hellcat-powered Challenger ADR. We'll just have to wait and see.

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.
