Jeep Chief and Wrangler Red Rock Responder teased ahead of Easter Jeep Safari

Jeep is being coy about it's lineup for the 2015 Moab Easter Jeep Safari, releasing just a pair of shots and an exceptionally brief press release on two of the seven concepts coming to the desert later this month. So, what can we glean from the limited assets that have been given to us? Well, as we said, we know Jeep is bringing seven vehicles to its big festival. We also know the names of two vehicles, shown above – there's the Chief and the Wrangler Red Rock Responder. Which is which? A fair question. We're betting the second image is the Wrangler-based Red Rock Responder. As for the Chief, well, we've absolutely no idea what to expect there. Jeep's Moab concepts generally include the model name on which their based – see the Grand Cherokee Trail Warrior and Cherokee Dakar from last year, or even the Wrangler Red Rock Responder, mentioned above. There's no such moniker on the Chief. As for the Chief's illustrated teaser image, as we said, it doesn't reveal much. The body is angular, and quite Jeep like, with squared-off wheel arches and decidedly old-school taillights. Beyond that, though, we don't have much to go on. Expect much more not just on the Chief and Red Rock Responder, but on all seven of the concepts Jeep is bringing to Moab. The party starts on March 28 and runs until April 5. Be sure to check back then for full coverage. Related Video:

Chrysler recalls small number of 2013-2014 cars and trucks over engine debris

Chrysler is recalling a small number cars over issues with their 2.4-liter four-cylinder engines. The recall, which affects 522 examples of its 2013 Dodge Avenger and Chrysler 200 models, as well as 2014 Jeep Compass and Patriot CUVs has to do with potential debris in the balance shaft bearings.
The abrasive stuff can cause the oil pressure to drop, which could lead to the engine stalling or outright failure. This situation could at best leave drivers stranded and at worst lead to a crash.
Chrysler will begin notifying owners, who will need to report in to have the balance shaft module replaced. All repairs are naturally free of charge. Scroll down for the bulletin from NHTSA.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
