Chrysler delays 2014 Jeep Cherokee media launch

Chrysler is making the unusual move of delaying the first media drives of the 2014 Jeep Cherokee, which were slated to start next week in Seattle. And while something like this is a rare occurrence, and one that most of the Autoblog staff can't recall happening this publicly or so close to the event itself, it won't effect the actual on-sale date of the new Cherokee, which is set to hit showrooms in September.
"Over the last couple of weeks during final quality and durability testing, we have discovered the opportunity to further improve powertrain calibration," Chrysler told Automotive News. This marks the second notable delay in the Cherokee's short life, after production was delayed for roughly a month earlier this summer.
Still, we'd rather Chrysler make sure the Cherokee is ready for primetime before flying media in from around the country. It shows a willingness to get things right the first time, rather than offering media drives and then tweaking the car after the fact.

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.

Chrysler Recalls 350K Vehicles To Fix Ignition Switches

Chrysler is recalling nearly 350,000 cars and SUVs to fix ignition switches that could unexpectedly shut off the engines. The recall covers 2008 Jeep Commander and Grand Cherokee SUVs, Chrysler 300 and Dodge Charger sedans, and Dodge Magnum wagons. All were built before May 12, 2008. Chrysler says the ignitions may not fully return to the "on" position after being started. The switches could move to "accessory" or "off." That could shut off the engine and knock out power-assisted steering and other features. Chrysler knows of one crash and no injuries from the problem. It's telling people to use the key alone in the ignition and confirm that switches have returned to "on" after starting their cars. Chrysler is investigating the cause. Customers will be notified when repairs are ready. Related Gallery The Trucks And SUVs Consumers Are Liking Most View 11 Photos
