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.

Supplier says Jeep Cherokee hack only affects FCA cars

Harman doesn't think that drivers need to worry about any further hacks of its products. The company supplies FCA's Uconnect infotainment system where a software vulnerability is responsible for a 1.4-million vehicle recall. "This experimental hack is unique to Chrysler," Harman CEO Dinesh Paliwal said to Automotive News. "This does not exist, to our assessment, in any other vehicle." The reason that the company wouldn't be involved is that automakers aren't simply plugging in the existing infotainment systems into new vehicles. According to Paliwal, Harman supplies the unit, but FCA and other automakers are able to make additional modifications for their vehicles. The National Highway Traffic Safety Administration has also recently taken up the question of broader software vulnerabilities in Harman's products. On July 29, the agency began investigating the company to check for similarities between Uconnect and the infotainment systems supplied to other automakers. The Jeep hack became national news when two researchers were remotely able to take control of a Cherokee. The vulnerability in the cellular connection even gave control over the brakes. "Once people get in the car and get into the CAN bus, then you can start to mimic and mess up many, many things in the car," Paliwal said to Automotive News. Politicians immediately responded with legislation to create federal standards in hopes of protecting drivers better. NHTSA also opened an investigation to make sure the automaker's software update actually solved the problem. Related Video:

Next-gen Jeep Wrangler to get 8-speed automatic and 3.0-liter EcoDiesel

Following up on previous reports, an anonymous source within FCA has confirmed to Autoblog that the next-generation Jeep Wrangler will come to market with both a 3.0-liter, EcoDiesel V6 and ZF's critically acclaimed eight-speed automatic transmission. While this pairing makes a lot of sense (we'll explain why in a minute), until now, we only had limited reports that either item would arrive in the next-generation Wrangler. This is the first time we've heard that the eight-speed automatic and the diesel would be paired together. That said, we shouldn't be surprised by this news. FCA currently sells the Jeep Grand Cherokee and Ram 1500 with the diesel/eight-speed gearbox combo, making its inclusion in the next-gen Wrangler far from an Apollo 11-caliber feat of engineering. Naturally, we reached out to Jeep for an official comment. Spokesperson Gabrielle Schulte gave us the expected response to this kind of inquiry, telling Autoblog that FCA does not comment on future product. Jeep has flirted with the idea of a diesel Wrangler for some time, with CEO Mike Manley telling Ward's Auto just over two years ago that a Wrangler diesel was "on the radar," although at that time, we weren't certain whether it'd be the 3.0-liter EcoDiesel showing up in the rough-and-tumble off-roader. As for the eight-speed, SEC filings back in November revealed that it'd be coming to the Wrangler in 2018. Our source could not confirm which model year the 8AT/diesel would arrive in. Related Video:
