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.

Ward's announces 10 Best Engines 2015

Ward's Auto has named its 10 Best Engines for 2015, covering a range of powerplants from fuel-sippers to fire-breathers. As with past years, forced-induction reigns supreme, with seven of the ten engines featuring a turbo or supercharger. This year is slightly different, though, as two of the seven blown engines are turbocharged three-cylinder mills, from the Ford Fiesta and Mini Cooper. They're joined by the 2.0-liter turbo four from the Volvo S60, the 1.8-liter turbo four from the Volkswagen Jetta and the 2.0-liter boxer from the Subaru WRX. BMW and Chrysler were the only marques to be named to this year's list twice, with the electric motor from the i3 joining the Mini's three-pot, and the 3.0-liter turbodiesel V6 in the Ram 1500 and Jeep Grand Cherokee repping the diesel crowd, alongside a certain supercharged monster. Hyundai also took a prize with a zero-emissions powertrain, with the Tucson FCV's 100-kilowatt fuel cell making the list (apparently Ward's is quite generous with what it deems an "engine"). Rounding out the list are two Autoblog favorites, each displacing 6.2 liters, but producing their power very differently. On the one hand, Chevrolet's overhead-valve, 455-horsepower V8, found in the Corvette, makes its power the old fashioned way. And in the other corner, we have one of the most exciting engines of the year – the 707-hp, 6.2-liter, supercharged Hellcat V8, featured so prominently in the Dodge Challenger and Charger SRT Hellcat. "We spend a lot of time reading the powertrain tea leaves throughout the auto industry, and we're proud that this year's list is a microcosm of all the latest innovation coming from automakers," said Ward's Editor-in-Chief Drew Winter in a statement. "It's not just a list for enthusiasts or for environmentalists," he says. "There's something for every vehicle shopper and every budget. All the powertrains on this list deliver a first-rate driving experience," Winter added. Scroll down for the full list from Ward's, and let us know which engines you think belong and which should have been included in this year's rankings.
