Jeep teases Trailcat and other Easter Safari concepts

Update: It's confirmed. The Trailcat is a Hellcat-powered Wrangler concept. Stay tuned for more details. Ahead of the 50th annual Easter Jeep Safari in Moab, Utah, the company is teasing two of the seven concepts it'll be taking along. There are virtually no solid details about these two Jeeps, save that they exist. But just reading the word scrawled across the Jeep Wrangler Trailcat concept's hood gets the blood pumping. We've been hearing about Hellcat-powered Jeeps for a while now. The Grand Cherokee Trackhawk has been the subject of a steady drum-roll of rumors and reputed confirmations, and even a spy video. But that's the Grand Cherokee. But a Wrangler? The aftermarket has been fooling with it. A company called Hauk will stuff one in a Wrangler for you, and surely other companies will follow. For Jeep itself to stuff one into a concept vehicle seems like a great way to fire up the diehard Wrangler folks. The other concept is called the Jeep Crew Chief, and it looks like an update of the Jeep Chief concept from last year. That incredible, retro design recalled the SJ-generation Jeep Cherokee of the 1970s and '80s. Last year's Chief was based on a Wrangler Unlimited, with the rear doors slightly disguised to emulate its two-doored forbearer. Based on the "Crew" part of the name, we can surmise it might be a crew-cab pickup conversion with the wonderful Chief front end. Expect it to be a hit, as well.

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.
