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.

Watch this 650-hp Hennessey Jeep Grand Cherokee go from 0-60 in 3.9 seconds

Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower - 530 hp at the wheels, according to Hennessey - and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.
There's more than just a Roots-type supercharger bolt-on, with ported cylinder heads and high-flow headers among the many changes made to the engine. You can watch this pre-2014 facelift silver model prove its spec sheet on the drag strip in the video below.

Jeep Wrangler to remain in Toledo, get a pickup version

Production of the Jeep Wrangler is staying in Toledo, OH, and it might be getting a pickup in the near future, according to Automotive News. Meanwhile, Cherokee production is leaving Ohio. The announcement was reportedly made to plant management earlier today. "We found a solution that accommodates a variety of other interests to us because of the way in which we can move some product around," CEO Sergio Marchionne said to Automotive News. A Jeep spokesman declined to comment to Autoblog. Right now the official details about FCA's production plans are still hazy. However, an official announcement is expected when the automaker has a deal with the UAW, which could be by Sept. 14. According to insiders speaking to AN, the Wrangler pickup would join the lineup in 2017 or 2018. While losing the Cherokee doesn't help the Toledo factory, the new pickup should take up some of the slack. It also keeps Wrangler production going in Ohio until the next-generation model launches in 2018. The Cherokee is expected to move to the Sterling Heights Assembly plant in Michigan or Belvidere Assembly in Illinois because they build vehicles on the same platform, AN reports. The future of Wrangler production has been a hot topic at the Toledo plant for the entire year. There was initial speculation that model might leave the factory if it moved to an aluminum body. However, the latest reports offered some hope of the Jeep remaining there. Last week, Autoblog's sources at FCA also said that the Wrangler pickup was coming but couldn't confirm a timeframe.
