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.

How to update and secure a vulnerable Chrysler Uconnect system

If you own one of the 1.4 million vehicles affected by the recent Chrysler software recall, you may want to watch this video. In it, we explain how to get the latest infotainment software loaded onto the 8.4-inch Uconnect system. The recall was a response to the findings of researchers who were able to hack into and remotely control a 2014 Jeep Cherokee through its cellular connection. Although Fiat Chrysler has worked with Sprint to plug most of the holes on the carrier side, there are still some vulnerabilities that only this latest software version can patch. Owners have three options to get the update: download it now, wait for a USB stick in the mail, or take the vehicle to an FCA dealer. Chrysler will be sending USB sticks loaded with the software update to customers. Anyone with an internet connection and a USB stick of their own with at least 4 GB capacity can speed things up by downloading the patch from the Uconnect website. We cover that process from start to finish in the video, with the final portion still applicable to those using the FCA-supplied USB stick. If after watching this you still don't want to tackle the patch yourself, you can take your vehicle to the dealer to have it done. Also note that this process is the same for all Uconnect updates, not just the one patching the exploits. Our demonstrator vehicle is a 2015 Ram 1500 pickup. The procedure should be very similar on other products with the 8.4-inch Uconnect system, with only the location of the USB port varying. Once you have the USB stick with the software on it – either after having downloaded it yourself or receiving it in the mail from Chrysler – the installation process is relatively simple. It takes about 15 minutes to perform the update; we edited out the wait in the video. To check whether or not your car's 8.4-inch Uconnect system is running the latest software, go to System Information on the touch screen's Settings page and look at Software Version. The update related to the recall is version 15.17.5. Related Video: Recalls Chrysler Dodge Jeep RAM Safety Technology Infotainment Videos Original Video hacking

Tesla Model 3: Finding perspective

The reveal of the Tesla Model 3 this week was one of the biggest automotive events of the year. The car attracted 180,000 pre-orders in just 24 hours, gave the company's stock a jolt, and set Tesla on a more ambitious growth path for the rest of the decade. It's a staggering feat considering the Model 3 is one car, from one company that's just 13 years old. It begs the question: Is all of this attention warranted? Barclays analyst Brian Johnson urged investors to "take a deep breath," and be mindful that the Model 3 won't likely arrive in "significant volume" until possibly 2019. Though Tesla promises the car will launch in 2017, Johnson points to the slow rollouts of the Model S sedan and Model X crossover as cautionary notes. The potential extended wait didn't temper the enthusiasm of Tesla's faithful, and many put down deposits before they had even seen the car. Johnson compared the hype to a "Black Friday atmosphere," saying the social media buzz went from "insane mode to ludicrous mode," in a riff on Tesla's driving features. Still, the Barclays analyst was admittedly "curmudgeonly" when it came to Tesla's stock price. In comparison, Morgan Stanley called Tesla's shares undervalued, and expects the Model 3 to be the start of cataclysmic changes in the industry. "We have said for some time that, despite its many worthy accomplishments, Tesla had not yet truly disrupted the auto industry," according to a report led by Adam Jonas. "We are now getting a feeling that this may be starting to change." The Model 3 offers a range of 215 miles on a single charge, can sprint to 60 miles per hour in less than six seconds, and has room for five. It will also be capable of charging on Tesla's supercharging network and features the company's autonomous technology. With a starting price of $35,000 before incentives, it's arguably the most futuristic car that's attainable for a wide swatch of American buyers, though the Chevy Bolt EV is comparable (200-plus-mile range, $37,500 MSRP before incentives) in many ways. The Model 3's attainability is what partially drove the hype. It was like Elon was whispering: Y ou can own the future. The question is now: Can Tesla deliver? If it does, this early fanfare will be richly deserved. News & Analysis News: Top Gear appears to be in turmoil as Chris Evans works four hours a day. Analysis: Is this a soap opera or a car show?
