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.

Jeep mulling power top for next Wrangler

Jeep is hard at work on the next-generation Wrangler, though the truck is still a few years from hitting the trails. The new model will still be aimed at off-roaders, but rumors suggest it will be a little more comfortable than previous versions to appeal to more people.
According to Road and Track, Jeep is developing a power-retractable top as an expensive option for the Wrangler. There is no word if the top in question is a sliding canvas rollback like the ones found on many European vehicles or a full convertible hardtop or softtop, nor do we know whether it would be made available on two- or four-door models. It might be a nice feature for some buyers but would certainly add complexity to a truck already known for its ruggedness. We asked Jeep for confirmation, but Jeep spokesperson Todd Goyer could only remind us that the company "can't comment about future products."
In news that is likely to irk the faithful, R&T reports the next model may also ditch its folding windshield for improved safety and possibly even get rid of its rear-mounted, full-size spare tire. The new Wrangler won't go completely soft, though, and will reportedly still feature removable doors and solid axles.
