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.

2014 Jeep Cherokee facing production delay

Jeep's bold-faced new direction spearheaded by the 2014 Cherokee is facing some teething issues. According to a report by the Detroit Free Press, production start-up of the controversial new utility vehicle at its Toledo North facility is running about a month behind schedule "due to a wide range of issues." That's according to Mark Chernoby, senior vice president of engineering at Chrysler.
Chernoby maintains that the issues being encountered aren't unusual for the launch of a new vehicle - particularly one with a new powertrain - and he downplayed the delay, telling Jeep dealers that they "will have ample inventory of the midsize SUV by fall." Among the kinks being worked out? Calibrating the Cherokee's cutting-edge ZF nine-speed automatic transmission and refining assembly line tasks to make the process more efficient.
Chrysler expects to start building retail-ready versions of the Cherokee around mid-June, with official sales slated to start in September.

2016 Jeep Wrangler to ditch solid axles to save weight?

Hey, Jeep fans. If you think the idea of a funky-looking, car-based Cherokee revival is offensive, have a listen to what might be in store for the next-gen Jeep Wrangler. Automotive News is reporting that as Jeep develops the 2016 Wrangler, weight reduction is a crucial target, and the Wrangler's rugged solid axles could be sacrificed in the name of better fuel economy.
We've already heard the next Wrangler will go on a serious diet using aluminum body panels and an air suspension system, so the idea of a four-wheel independent suspension setup for this OG SUV isn't all that surprising. Besides, it's not like an independent suspension would limit the Wrangler's off-road abilities - just check out the Hummer H1. In fact, it might be the aftermarket parts companies - not Wrangler enthusiasts - who would be most disappointed by such a drastic suspension change, as the article states that the Wrangler's solid axles and coil-link suspension make it the most popular SUV for customization.
There are probably still a couple years before we'll start hearing any concrete details about the 2016 Wrangler, at which time it will be interesting to see how stricter fuel economy and crash safety regulations have been balanced with traditional Wrangler cues like its removable doors and roof and folding windshield. Let us know in the comments below if a Wrangler sans solid axles is any less of a Wrangler.
