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 Liberty replacement takes shape

Now that the Liberty has left us for greener pastures, it's time to start looking into the future of the midsize Jeep model. The next all-new vehicle for the off-road brand will be the SUV you see here, effectively replacing the Liberty, and not necessarily carrying on with that name.
From the sides, the prototype you see here sort of looks like a miniature version of the handsome Grand Cherokee, albeit with a bit more in the way of body sculpting. Up front, the seven-slat grille will be front and center, with completely revised headlamp designs that are reportedly angular and sweep well into the front fenders (you can sort of see what we're talking about in the side profile). That doesn't sound very Jeep-like, but we'll reserve judgment until we, you know, see the thing.
The bigger question with the Liberty replacement will be whether or not its off-road chops will be up to snuff. After all, the two previous generations of Liberty models were body-on-frame traditional SUVs, whereas this new Jeep rides on a larger version of the Dodge Dart platform.

2013 Jeep Wrangler Unlimited Rubicon 4X4

Ice skates are spectacular on frozen water, yet they are dreadful everyday footwear. I consider the Jeep Wrangler equally as specialized.
I recently spent a week with a 2013 Jeep Wrangler Unlimited Rubicon 4X4. Introduced for the 2007 model year, the Wrangler Unlimited is a standard JK two-door with 20.6 inches added to its wheelbase and two additional doors bolted to its passenger compartment. While Jeep offers the Unlimited in seven different trim levels, the desirable Rubicon is the most capable when the pavement ends, as it boasts a slew of hardcore off-road tools including front and rear electronic locking differentials and a front sway bar that can be disengaged at the touch of a button for improved articulation. My I-Look-Like-A-Traffic-Cone test model started with a base price of $34,095 (plus $995 destination). Options including a five-speed automatic transmission, Uconnect, tow package and a premium soft top, drove the bottom line up to $38,630.
