Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

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.

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:
