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.

Dodge Durango could get eTorque mild hybrid system in 2020

The 2020 Dodge Durango appears slated to get a mild-hybrid powertrain option. That's the word from moparinsiders.com, which unearthed the news from documents relating to contract negotiation between the FCA and the UAW. Although the documents give no further details, it's a pretty safe bet that we're talking about Chrysler's eTorque mild-hybrid system, which was introduced on the Ram 1500 pickup and has since been extended to the Jeep Wrangler. Currently, the Wrangler offers the eTorque system on the 2.0-liter inline-four and the 3.6-liter Pentastar V6, both on the Sahara model only, while the Ram 1500 makes the mild-hybrid system standard with the 3.6-liter V6 and an option with the 5.7-liter Hemi V8. The V6 eTorque powertrain makes 305 horsepower and 269 pound-feet of torque (Ram) or 285 horsepower and 260 pound-feet (Wrangler). The Wrangler's four-cylinder eTorque is good for 270 horses and 295 lb-ft. The V8 version in the Ram is good for 395 horsepower and 410 lb-ft of torque. In all cases, the eTorque system does not increase peak output over the standard version of the gasoline engine. The mild-hybrid system does provide a minor fuel-economy boost. In the Wrangler, the 3.6-liter with eTorque has EPA city estimates that are 1 mpg better than without the system. On the Ram's V8, eTorque adds 2 mpg city and 1 mpg highway. (The 2.0-liter sees no improvement in its EPA ratings.) It's not known whether the Durango will add eTorque to its V6, or V8, or both. Either engine could do with a fuel-economy boost, as the V6 is EPA rated at 19/26 mpg city/highway (RWD) and 18/25 mpg (AWD), while the V8 version has estimates of 14/22 mpg. Related Video:

Jay Leno drives a 1970 Dodge Charger with 1,650 horsepower

When Jay Leno says a vehicle might have too much horsepower, he's got our attention piqued. That's exactly what he thinks about the 1970 Dodge Charger Tantrum from Wisconsin-based SpeedKore Performance. While it still looks like a classic muscle car, the front end now features a carbon fiber hood and fenders. Underneath the lightweight parts, there's a twin-turbo, 9.0-liter Mercury Marine offshore boat racing engine with an astonishing 1,650 horsepower, or an only slightly less asinine 1,350 hp on pump gas. Jay is very mechanically intrigued by the Charger at the beginning of this video, and puts it on the lift to take a look at the underside. The engine plumbing is a thing of beauty, and the mill packs a massive radiator and intercooler to keep things running cool. Leno's drive in the Tantrum is especially interesting. The beastly engine is difficult to control, and anything above half throttle in most gears can spin the rear tires. The significant turbo lag also makes the power unpredictable. When Jay finally finds a straight piece of road, he puts the hammer down and rockets into the distance. And, of course, you know Jay's not going to end the video without some suitably smoking tires.
