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 Renegade sales being held due to powertrain issue [UPDATE]

UPDATE: An unnamed FCA US source has clarified to Automotive News that while there is a software issue, it does not concern the transmission. The Jeep Renegade appears to be facing early software problems that are similar to the ones at the introduction of the Cherokee a few years ago. The issue is keeping the brand's latest compact crossover away from dealers until the situation can be resolved. The fault reportedly deals with the software controlling the Renegade's nine-speed automatic transmission. FCA CEO Sergio Marchionne briefly talked about what was happening in an interview with Automotive News. "I'm having a very bad engineering day," he said. "It's a combination of attributes of that vehicle that is making my life horrible." The company boss predicted at the longest it could take until mid-June to fix things. Through April, Jeep has sold 5,157 Renegades, including 4,214 of them in that month alone. Autoblog reached out to an FCA US spokesperson to learn more about the software problem, but the company had no comment. Getting the software right to control the nine-speed automatic plagued development of the Cherokee. The issues delayed the model's launch in 2013, and the company was still releasing improvements for some vehicles this year.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.
