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.

2014 Jeep Grand Cherokee gets surprisingly comprehensive update, new diesel power

Traditionally, automotive journalists can be heard muttering something to the effect of "Geeze, it's about time!" whenever a vehicle's midcycle refresh is revealed. As we routinely see and drive new models many months before the public even claps eyes on them in showrooms - and then go on to tweeze apart their minutia in our daily writings - perhaps some impatience is to be expected. With so much exposure to a given vehicle, it's fair to say we tire of most cars and trucks far more quickly than the average consumer.
The alterations are handsome, if not subtle touches from the "If It Ain't Broke" school of design.
Which is why we're pleased to say "Oh, is it time for that already?" when it comes to the 2014 Jeep Grand Cherokee. The current WK2 Grand Cherokee hit the market in 2011 and climbed its way into our hearts with its rugged good looks, go-anywhere capability and surprising refinement. We're not yet tired of its appearance or performance, but even so, we're very glad to see Chrysler giving its flagship Jeep some attention, including a much-anticipated diesel powertrain option and some other economy-minded measures.

2015 Jeep Renegade Trailhawk [w/video]

There are two avenues to the world of off-roading. Arguably the more popular is to pick up a second- or third-hand Jeep, Land Rover or pickup truck and go wild with the aftermarket. The opposite approach, though, is to simply buy new, which brings a warranty along with the most up-to-date off-road tech fitted by the factory (despite likely lacking the ultimate capability of an aftermarket-imbued vehicle). That second option has, traditionally, been pricey. Take our long-term Jeep Cherokee Trailhawk, which rings up at just over $38,000. A Ford F-150 SVT Raptor is going to be an even more expensive proposition, while the undisputed kings of luxury off-road performance from the factory – the Range Rover, Toyota Land Cruiser and Mercedes-Benz G-Wagen – will require ownership of a medium-sized oil well. With all due respect to those who take their Trail-Rated Jeep Patriot models off-road, the all-new Renegade Trailhawk is such an exciting proposition because it brings the cost of a warranty-backed off-roader down significantly, while also delivering a degree of trail-rated performance that should easily fulfill the needs of the average enthusiast. Drive Notes Before we get into what it adds, it's worth noting that the Trailhawk trim does have a small impact on the Renegade's on-road abilities. As we said in our original feature, the TH adds a significant amount of weight to the standard CUV, as it tips the scales at nearly 3,600 pounds. That mass, combined with the slightly higher stance, means the off-road model doesn't handle quite as well as a lesser Jeep. It also doesn't feel as fleet of foot, as it retains the same 2.4-liter, 180-horsepower four-cylinder and nine-speed automatic found throughout the Renegade range. Despite the downers, the Trailhawk trim does bring quite a lot to the Renegade package, most notably in the form of a bespoke version of Jeep's Active Drive all-wheel-drive system. The upgraded system features a dedicated 20:1 crawl ratio while the Selec-Terrain system is home to a new Rock setting. Beyond that, Jeep lifted the Renegade's ride height eight-tenths of an inch, increasing overall ground clearance to 8.7 inches and delivering 8.1 inches of wheel articulation. This is complemented by unique front- and rear-fascias, which up the approach and departure angles to 30.5 and 34.3 degrees, respectively, besting the Cherokee Trailhawk's 29.8 degrees and 32.1 degrees.
