Jeep's Wrangler Hellcat and six other sweet concepts for Moab

Jeep. Wrangler. Hellcat. You read that correctly. And while it's just a concept for this year's Moab Easter Jeep Safari, it has us dreaming about blasting through the desert at 200 miles per hour. Fiat Chrysler Automobiles released a whole slew of Easter Jeep concepts at an event at the company's Auburn Hills, MI, headquarters today. The 50th annual Moab Safari will take place in just a couple of weeks – it's a sort of mecca for Jeep owners, and for the past few years, FCA brings its concepts out to the rocks and trails of Moab to prove that these are more than mere one-off, delicate showcars. Our own Brandon Turkus was live at FCA's reveal event, and he passed along a bunch of notes, in addition to the official stuff from Jeep. Here are some details about each concept, with full photo galleries and videos of each Jeep creation.

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.

Jeep Grand Cherokee redesign delayed

The launch of the next-gen Jeep Grand Cherokee is being now being pushed back until late 2018 or even into 2019, Jeep CEO Mike Manley indicated Friday, according to Automotive News citing a Reuters report. Under the original five-year plan, the SUV was supposed to be replaced in the third quarter of 2017. That would have made for a big year for Jeep with a refreshed Renegade and new Wrangler also slated for 2017. A delayed Grand Cherokee could send ripples through Jeep's product plans. The three-row Grand Wagoneer is meant to give the brand a vehicle to take on the Land Rover Range Rover, but it's supposed to use the same platform as the Grand Cherokee. This change is rumored to push that important model's launch further back. There's less uncertainty when it comes to the next-gen Wrangler. Manley said that the model was "broadly on track," according to Automotive News. The five-year plan aimed for a launch in the second quarter of 2017. Controversy, however, has swirled over possible plans to move the Wrangler from its longtime Toledo, OH, factory. One problem Jeep doesn't have to worry about right now is sales. According to Automotive News, Manley said volume was up 20 percent globally and could reach 1.2 million by the end of the year. He also indicated the brand was "on pace" to reach its 1.9-million-vehicle goal for 2018. The Grand Cherokee delay comes in the wake of rumors that FCA US is shuffling around its previous five-year vehicle launch plan to postpone several models. Related Video:
