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 defies NHTSA, says it won't recall 2.7M Jeep Grand Cherokee, Liberty models

Facing a possible recall totaling around 2.7 million of its most popular SUVs, Chrysler remains insistent that the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty are safe vehicles. This comes on the heels of a recall request from the National Highway Traffic Safety Administration for these two models due to fuel tanks mounted behind the rear axle, which could possibly be ruptured during severe rear-end collisions, leading to an increased risk of fire. In response to the allegations, Chrysler says that it does not agree with NHTSA nor does it plan on recalling either vehicle.
Chrysler said both SUVs "met and exceeded" the requirements for fuel-system integrity, and cooperated fully with NHTSA since the investigation was opened in 2010. While 15 deaths and 46 injuries have been reported from fires caused by rear-end collisions on these models, Chrysler is claiming that the vast majority of incidents cited by NHTSA were "high-energy crashes," including one where a stopped Grand Cherokee was rear-ended by a tractor trailer going 65 miles per hour.
The automaker wraps up by saying "NHTSA seems to be holding Chrysler Group to a new standard for fuel tank integrity that does not exist now and did not exist when the Jeep vehicles were manufactured." Scroll down for Chrysler's official response to NHTSA, but we're pretty sure this isn't the last we've heard on this issue.

New 2018 Jeep Wrangler is definitely a Jeep Wrangler

Jeep is hiding details on the new Wrangler about as well as a colander holds water. The good people over at JL Wrangler Forums have managed to get ahold of some new images of the next-gen Wrangler. Surprise! It looks exactly how we expected it to look. These new images give us our best view yet, showing a number of details that we couldn't even glean from spy photos. Enthusiasts can put down their pitchforks. The Wrangler can still go topless. The two images - one of the front and one of the rear - show off what appears to be a Wrangler Unlimited Rubicon. The second photo is notable since it finally confirms that the doors and roof are fully removable, a feature that some feared would disappear with the new model. It looks like a fixed roll cage will help strengthen the Wrangler and protect occupants in the case of an accident. Hinges up front mean the windshield is still able to fold forward as well. The rest of the Wrangler, though all new, just updates the Jeep's timeless design. Up front, the grille is canted rearward at the top, the fog lights move to the ends of the bumper, the turn signals move to the front of the fender, and the hood latches are pushed forward a bit. The windshield appears to be a bit more upright and less curved than the current model. Around the side, we can see new vents behind the rear fenders. The door hinges looks smaller, and the mirrors have integrated side marker lights. There is a new line that cuts below the windows, flowing to the rear of the Wrangler. At the back, we can see that the tail lights now wrap around to the Wrangler's side, though they still look like the square lights we've always had. There is no sight of a rear-mounted spare, but plenty of spy shots have shown that it should carry over, new backup camera and all. It also looks like the new mounting points for the roll cage should provide a bit more cargo space. Look for more news, images, and renders as the Wrangler's development moves along. Related Video:
