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.

Jeep Wrangler Polar Edition coming to America

Jeep originally took the wraps off its Polar Edition Wrangler at the Frankfurt Motor Show in September, and at the time, we figured this would be a Europe-only affair. (Perfectly fine, since we US customers haven't exactly been lacking special edition Wrangler models over the years.) But now, and as Jeep says, just in time for winter, the automaker has announced that the ice cold Wrangler will be hitting North American showrooms in November.
Based on the Wrangler Sahara model, the Polar Edition can be had in either two- or four-door body styles, with a unique Hydro Blue paint job as the featured color. (Buyers can also opt for less-special Billet Silver and Bright White hues.) Other exterior enhancements include a body-colored hardtop, 18-inch gloss black wheels, the Powerdome (power bulge) hood, and unique decals all around the body.
But the Polar Edition isn't just about some paint and stickers. Jeep has fitted this Wrangler with a Dana 30 front axle and Dan 44 rear axle, as well as the Trac-Lok anti-spin electronic rear differential. Like all US-spec Wranglers, the Polar Edition uses Jeep's 3.6-liter Pentastar V6, producing 285 horsepower and 260 pound-feet of torque. Both a six-speed manual and five-speed automatic transmission are available.

Why Mopar won't release a factory lift kit for the new Jeep Cherokee

The Jeep Cherokee Dakar concept showed off at the 2014 Easter Jeep Safari made a lot of online friends, even the Cherokee naysayers assenting that there's a monster Jeep underneath the Cherokee's skin if you're willing to go in and get it. But after reading Road & Track's write-up of what went into creating the Dakar, particularly its lift, you'll understand why you'll probably never see the components for it in the Jeep Performance Parts catalog.
The concept's press release mentions a "prototype Jeep Performance Parts lift kit, and additional suspension modifications." The short-story explanation is that the front struts on the standard Cherokee weren't engineered to accept any amount of lift, so the long story begins with the phrase, "an entirely new suspension." Head over to RT to read the details, and don't be afraid to ogle the Cherokee Dakar gallery and another awesome Jeep fancy that won't likely crawl over the hurdles imposed by production reality.
