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 Charger Hellcat hitting 60 in 2.9 seconds on drag radials?

The Dodge boys and their cousins from SRT have shoehorned the same 707-horsepower, 6.2-liter supercharged V8 into both the Dodge Challenger and Charger. The former being a two-door, it's lighter than the latter four-door sedan. So it would stand to reason that the Dodge Challenger SRT Hellcat would be the quicker of the two, right?
Only that's not necessarily proving to be the case. On stock rubber, yes, the coupe beats the sedan: Dodge quotes a 0-60 time of 3.7 seconds for the Charger SRT Hellcat and 3.5 for the Challenger. Same gap across the quarter-mile: 11 seconds flat for the Charger versus 10.8 seconds for the Challenger. But according to recent reports, the story changes when you put both on drag radials.
While visiting Chrysler HQ in Auburn Hills, MI, TorqueNews.com caught wind of performance figures for the Charger Hellcat on drag tires: 0-60 in a mind-blowing 2.9 seconds and a quarter-mile in just 10.7. The latter figure just barely pips the Hellcat-powered Challenger's NHRA-certified figure of 10.8, making the Charger not only the fastest sedan on the market, but also the fastest muscle car. What isn't immediately clear, however, is whether the drag radials in question have any tread on them and are street-legal, or if they're pure slicks confined to a closed strip.

Chrysler investing $20M in Toledo plant to support 9-speed auto production

In 2011, Chrysler announced a $72-million investment in its Toledo Machining Plant to modernize production of the eight- and nine-speed torque-converters for automatic transmissions made there. That upgrade work won't be finished until Q3 of this year, but Chrysler has already announced a further $19.6-million investment to increase production capacity for the nine-speeders.
The extra units will be necessary because the nine-speed transmission they'll be mated to is going into three popular models: it will debut on the 2014 Jeep Cherokee, then go into the Chrysler 200 and Dodge Dart. The company predicted that this year alone it would sell 200,000 units equipped with the nine-speed tranny, and it is spending some $374 million in addition to the investment in Toledo to upgrade production capacity for it.
The work attached to this new investment won't begin until Q3 of 2014, and it will be finished by the end of that year. There's a press release below with all the details.
