2014 Easter Jeep Safari kicks off with six concepts

The 2014 Easter Jeep Safari is set to begin this weekend in Moab, Utah, and while it's sure to be a blast for Jeep enthusiasts from all corners of the world, we're looking forward to the wild, off-road ready concepts that Jeep will be bringing to the red rocks. As you can see in our handy headline, there are six such vehicles in total, each of which sports a variety of tweaks and custom bits.
Unlike in years past, where Jeep graced us with some outrageous concepts like the Mighty FC or J-12, this year's vehicles are a bit more restrained and a bit more buildable by enthusiasts. That's not by accident, officials tell us. They wanted to put this year's focus on attainable vehicles and accessories from Mopar and Jeep Performance Parts that existing owners can use to augment their own vehicles. So let's get to it.
We'll start with the Wranglers first. There are three concepts of the jeepiest of Jeep coming to Moab - the Level Red, Maximum Performance and Mojo. The Level Red and the Mojo (seen above) are similar from a suspension and engine standpoint. Both boast a two-inch Jeep Performance Parts lift kit, which officials tell us is coming to market in the next few months. There are a pair of Dana 44 crate axles on both the front and rear, while a Jeep Performance Parts Rock-Trac transfer case has been fitted. The 3.6-liter V6 engines on both Jeeps can breathe a bit easier thanks to a new cold-air intake and exhaust system.

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.

NHTSA closes probes on Jeep Grand Cherokee, Ford Freestar and Mercury Monterey

The Detroit News reports the National Highway Traffic Safety Administration has officially closed its investigations into 2012 Jeep Grand Cherokee, 2004-2005 Ford Freestar and Mercury Monterey models. The separate probes found no issues that pose safety concerns. NHTSA began investigating certain Grand Cherokee SUVs over complaints that power steering hoses could detach during operation, thereby increasing the risk of a vehicle fire. Of the 24 reports of failure, none alleged smoke or fire in the engine bay, and Chrysler has since modified the power steering cooler assembly to reduce the likelihood of the failure.
Meanwhile, certain Ford Freestar and Mercury Monterey vehicles garnered a government probe after receiving complaints that the models were equipped with faulty scissor jacks. The agency had received six reports of the jacks failing or causing injuries, including one incident that resulted in a fatality. But NHTSA says the jack failure rate is similar to those found in other vehicles. In those six cases, the government agency found the jacks were being used for something other than changing a tire, and investigators could not determine whether the emergency brake was set or the rear tires were properly chocked.
