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.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

2015 Ram 1500 Rebel priced from $43,985

Ram has announced the prices for the two newest members of its 1500 family, with the new Rebel starting at $43,985 and the Laramie Limited kicking off at $51,870. Those prices include the $1,195 destination charge. The Rebel's starting price is only for the two-wheel-drive variant. Adding four-wheel drive elevates the price to $45,915 and includes the 3.6-liter Pentastar V6. If you fancy four-wheel drive and FCA's 5.7-liter Hemi V8, you'll need to write a check for $47,565. The luxurious Laramie Limited comes in a few more varieties, and can be had with either two- or four-wheel drive, and gas or diesel power. The base model uses the 5.7-liter Hemi V8 and rear-wheel drive, for a total price of $51,870. Plan on an extra $3,120 to replace the Hemi with the 3.0-liter EcoDiesel V6. Adding four-wheel-drive adds $3,505 regardless of engine.
