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.

The final-year Viper special editions sold out so fast Dodge is adding more

Viper collectors don't mess around. After Dodge opened ordering for its 25th anniversary 2017 Viper models – some of the last ones that will be built – all of the cars were spoken for in just five days. The company managed to sell 206 cars, an average of about 41 per day. Compare that to the 241 Vipers sold through May of this year and you can see why special editions make good business sense. Demand was so strong that Dodge will add a sixth special-edition for the Viper's last year of production. Within the group of five initial special packages, the winner was the 1:28 Edition ACR; all 28 went in 40 minutes. Dodge sold the 31 VooDoo II Edition ACRs in two hours, while 25 Snakeskin Edition GTCs and 100 GTS-R Commemorative Edition ACRs took two days to sell out. The 22 Dodge Dealer Edition ACRs took five days – apparently the dealers were too busy taking orders for the other 184 cars they didn't have time to order their own. The additional anniversary car is called the Snakeskin ACR. Dodge will build "up to" 31 of them, which we're pretty sure means exactly 31 if the previous demand is any indicator. The count matches the 2010 run of Snakeskin ACRs and will take the final-edition total to 237. We don't have any photos of that one yet, but you can get a good idea of what it will look like from the Snakeskin GTC. This one features Snakeskin Green paint, obviously, with a custom snakeskin-patterned SRT stripe, the ACR Package, the Extreme Aero Package, carbon-ceramic brakes, the ACR interior, a serialized Snakeskin badge on the instrument panel, and a custom car cover with the owner's name by the door. It will be available to order in the middle of this month, which means it will be sold out well by the end of the month. Chances are these and many of the others will go to mega-collectors like Wayne and D'Ann Rauh of Texas, who, at last count, owned 79 Vipers. Seventy-nine. Like we said, Viper collectors don't mess around. Related Video:

Old vs. New: 2014 SRT Viper takes on upgraded 16-year-old Dodge Viper

It's easy to play the "Would you rather have a New X or an Old Y with a bunch of upgrades?" game more often than we care to admit, but the crew at Car and Driver have taken bench racing to the next level with their latest video. In it, the magazine pits a brand-new 2014 SRT Viper against a highly modified 1997 Dodge Viper GTS. There are 16 years between the time this particular GTS rolled off the production line and when the new car bowed, but that doesn't mean the old snake's owners have been sitting on their hands.
Thanks to a spate of modifications, the GTS offers up a better power to weight ratio than the new machine, but is that enough to overcome the technological leap forward represented by the 2014 Viper? We won't spoil it for you. You'll just have to check out the full clip below for yourself.
