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: Beautiful Lands

Jeep emphasized the global nature of its all-new Renegade in a 90-second spot during the 2015 Super Bowl. Starting out in America, and with This Land is Your Land playing in the background, the spot splices images of the all-new Renegade with scenery from across the United States. As a global product and the first Jeep built outside the US, though, the spot quickly moves beyond America's borders, showing Renegades, people and scenery from around the globe. As for the Renegade, you can read all about it in our First Drive.

Weekly Recap: Hackers demonstrate auto industry's vulnerability

There's always been a certain risk associated with driving, and this week cyber security came into focus as the latest danger zone when researchers demonstrated how easily they could hack into a 2014 Jeep Cherokee from across the country. The incident raised concerns over the vulnerability of today's cars, many of which double as smartphones and hot spots. During the now-infamous experiment, Chris Valasek and Charlie Miller infiltrated the Jeep's cellular connection and were able to control the infotainment system, brakes, and other functions. The hackers told the Jeep's maker, FCA US, of their findings last year, the company devised a software fix. Though Valesek and Miller hacked a Cherokee (like the one shown above), several FCA products, including recent versions of the Ram, Grand Cherokee, Dodge Durango, and Viper were also affected, illustrating potentially wide exposure that could reverberate across the sector. "For the auto industry, this is a very important event and shows that cyber-security protection is needed even sooner than previously planned," Egil Juliussen, senior analyst and research director for IHS Automotive, wrote in a research note. "Five years ago, the auto industry did not consider cyber security as a near-term problem. This view has changed." Hours after the Cherokee hacking incident was publicized on Tuesday, Sens. Ed Markey (D-Mass) and Richard Blumenthal (D-Conn) introduced legislation to direct the National Highway Traffic Safety Administration and Federal Trade Commission to establish national standards for automotive cyber security. The bill also would require vehicles to have a cyber-rating system to alert consumers how well their cars' privacy and security are defended. "Drivers shouldn't have to choose between being connected and being protected," Markey said in a statement. "We need clear rules of the road that protect cars from hackers and American families from data trackers." Though FCA and its Jeep Cherokee were in the spotlight this time, they were just the latest to showcase how automotive technology has advanced faster than safety and regulatory measures. IHS forecasts 82.5 million cars will be connected to the internet by 2022, which is more than three times today's level. "Cyber-security will become a major challenge for the auto industry and solutions are long overdue," Juliussen said.
