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.

Junkyard Gem: 1963 Dodge Dart two-door sedan

The 1963-1966 Dodge Dart, sibling to the Plymouth Valiant, was sturdy, cheap, and easy to drive, and it sold very well. Here's a worn-but-solid example of the two-door '63 Dart sedan, spotted in a Denver-area self-service wrecking yard. The only transmission choices for the Dart this year were a three-speed manual and an automatic controlled by Chrysler's famous dash-mounted pushbutton shifter. These shifters worked surprisingly well, even when used for road racing. Starting in the 1964 model year, the Dart could be purchased with a 273-cubic-inch V8 engine, but in 1963 Dart buyers had but two engine choices: a slant-6 displacing 170 cubic inches and good for 101 horsepower and a slant-6 displacing 225 cubic inches and making 145 horsepower. This car has the big engine. This is one of the most reliable engines to come out of Detroit, period. The interior is pretty beat, but the metal isn't rusty. You'd think that someone would have rescued this car long before it came to this sorry end, but perhaps Dart restorers only want numbers-matching V8 cars these days.

Demon's NHRA competition ban: Good talking point, bad feature

One of the biggest headlines for the Dodge Challenger Demon is that, in stock form, it's so fast that the NHRA won't allow it to compete in the organization's events. It's the ultimate humble brag, "I can't drag race my car because it's so fast it was banned by the sanctioning body." Certainly Tim Kuniskis, head of FCA brands in North America, was excited. He told the press that he hugged the guy that brought him the letter banning the Demon from competition. Unfortunately, the reality is that not being NHRA-legal is kind of silly, and frustrating for owners who would want to actually race. Before we go too much farther, we should explain exactly why the Demon is illegal for NHRA competition. The car is capable of a sub-10-second quarter-mile time both on racing fuel and 91-octane pump gas. Cars that fast are required by the NHRA to have a full, certified roll cage, and the Demon doesn't. Now there are certainly ways to get around this. The most obvious would be for a Demon owner to have a company install a roll cage. Using less grippy tires than the barely street-legal Nitto cheater slicks would probably help bring that time down, too. There's also the option of putting the car into Eco mode, and, yes, the Demon has one. In Eco mode, the Demon makes just 500 horsepower, and trips the lights at the quarter-mile in 11.59 seconds, which will avoid the roll-cage requirement. However, none of these options are ideal. For one thing, if you bought an 840-horsepower car, you're not going to want to limit it when you get to a closed course such as a drag strip. Similarly, you're not going to want to ditch your super-sticky tires at the strip, especially when they're standard equipment. Finally, having to go aftermarket for a roll cage is an inconvenience at minimum, and it seems like a strange oversight considering the rest of the car. This is a car from the factory that comes with drag radials, no passenger seats, a racing fuel tune, air conditioned intercooler, and even skinny front wheels for drag racing. Its purpose is clear, but for some reason, Dodge stopped short of giving it a roll cage that would allow it to compete. Perhaps adding a roll cage would've made it difficult to pass safety regulations, and we would be more disappointed if the car wasn't allowed on the street. Even so, it seems like an odd stopping point.
