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.

What does Jeep have cooking with this stretched Cherokee?

Chrysler has been spotted testing what appears to be a stretched Jeep Cherokee prototype. Which seems odd, considering that Jeep already makes a Grand Cherokee, and that's an entirely different model. The question then is just what the company has in the works here. We don't know for sure – but we do have some ideas. We're anticipating a new Grand Wagoneer to serve as the brand's flagship model, but stretching the Cherokee's wheelbase to leapfrog the Grand Cherokee's would take more than eight inches – and stretching a "compact" platform to get there wouldn't seem to make a lot of sense. Alternatively Jeep could be looking to wedge a new model into its lineup in between the Cherokee and Grand Cherokee, potentially offering a third row of seats and wearing the Wagoneer name - sans the "Grand" - as part of a new range of seven-seaters. Just what the point would be, however, when the Dodge Durango already offers three rows based on the same platform as the Grand Cherokee, is a bit of a mystery. Another possibility is that it's not a Jeep at all, but rather a Dodge. The brand is in need of a replacement for the current Journey, and we're also waiting to see what FCA does to replace the Grand Cherokee since it unveiled the Chrysler Pacifica to replace the Town and Country. More of a crossover approach could take the Cherokee's Compact US Wide (CUSW) platform as its starting point, but stretched like this prototype to offer more space. Whatever it is, we're sure this won't be the last we'll have seen of it, so watch this space. Related Video:

Hands on with the concepts of the Moab Easter Jeep Safari

Jeep has a way of tugging at the heartstrings of its enthusiastic owner base when the annual Moab Easter Jeep Safari rolls around. The 2015 version sees all boxes ticked in the off-road event's 49th year: multiple diesel engines on display, a pickup-truck-like model and more than a few nods to the brand's long and storied history book. We were able to get a first-hand look at the seven concepts being shown in Utah's Red Desert in the much cooler, cleaner confines of the FCA Technical Center's Design Dome. Jeep Chief Concept We aren't sure if it's that throwback chrome grille or the eye-catching Ocean Blue paint, but even more than the Red Rock Responder, the Chief drew our eye as soon as we walked into the Design Dome. It's a surprisingly tall vehicle, but it's also very wide. We'd also wager it's longer than your typical four-door Wrangler. Jeep may have used a Wrangler as a base for the Chief, but any similarities to the donor vehicle are extremely difficult to spot. The fenders and doors are probably the biggest giveaways, but you're going to need to squint (and have the benefit of a Wrangler to compare with, like we did) to pick out Wrangler bits. As is the recurring theme throughout all seven concepts, the Jeep design team's attention to detail is borderline fanatical. From the "Surf Rated" badge on the fenders, to the tweaked door handles to the bumper stickers in the cargo area and the Tiki-statue-shaped shifter, the little details are truly the stars of the Chief Concept. The rosewood trim in the rear cargo area is stunning and adds to the Beach-Boy-friendly stylings of the Chief. The throwback grille, round headlights and tall, skinny taillights, meanwhile, add a lot of personality to the exterior. The high beltline and lower roof gives the Chief a chop-topped look, but it's arguably the least successful element to the blue concept's otherwise impressive design. All of the vehicles Jeep put together for Moab are 100-percent functional. That's not surprising with some of the vehicles you'll see below, but it somehow is remarkably impressive given the degree of the changes Jeep made in putting together the Chief. Jeep Wrangler Red Rock Responder The Wrangler-based Red Rock Responder is arguably one of the most capable of these real-world vehicles, both in terms of the way it looks and its actual hardware. We mentioned the special rescue equipment fitted to the bright-red, truck-like Jeep – a compressor and air gun, sockets, tow straps, etc.
