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.

Next Jeep Wrangler to keep solid axles

Jeep fans, you're not out of the woods yet, but the latest news is good: Automotive News reports that the next-generation Wrangler will stick with floating solid axles front and rear. Fiat-Chrysler wouldn't comment on the report, but the theory is that the combination of cost, capability, and ease of modification were deciding factors. We're sure the multibillion dollar aftermarket industry is also pleased. Remember, Jeep showed off the lifted Cherokee Dakar Concept at the Easter Jeep Safari last year, but the first ingredient in the recipe for jacking up its independent suspension was, "a whole new suspension." Above that there will be an aluminum body that's smaller than the current one, which Allpar says could be done with a narrower track and tighter gaps. It will sport a fixed windshield with increased rake to improve aero efficiency, and while there are rumors of a diesel-engined version that we'll finally get in the US, there's been no reliable info as of yet to back that up.

Jeep Renegade to show off new Mopar gear in Detroit

Jeep's adorable new Renegade is arriving in the US market soon (we're looking forward to driving it in a couple weeks), and to highlight that fact, the American off-road brand is trotting out a pair of Mopar-modified compact CUVs for the 2015 North American International Auto Show. Rather simply, Jeep has modified one Renegade to show off its prowess in the city, and another that plays up the crossover's off-road abilities. Despite their different purposes, both vehicles show off Mopar's parts catalog and Jeep's Authentic Accessories lineup for the new baby Jeep. The Urban Renegade borrows uses a Renegade Limited with Anvil paint as its base and draws from the Accessories catalog, adding a number of Omaha orange accents and satin black wheels. Mopar donated a bike-hauling trailer hitch to the rear of the Renegade, while its cabin features Katzkin leather-lined seats. Once again, Omaha orange accents brighten up the Limited's cabin. As for the off-road model, Mopar got a bit more involved, starting with the Renegade Trailhawk and adding satin black wheels with Colorado red trim and X-shaped graphics, borrowed from military jerry cans, to the Commando Green exterior. A number of prototype and one-off body mods were fitted to the Trailhawk, including a concept skid plate, rock rails and a new rear valence. Inside, Katzkin leather was applied to the Renegade's seats while the Omaha orange accents from the Urban Renegade have been replaced with Commando Green bits and bobs in the off-road model. Look for more on these new Renegade twins come Monday, when we hit the floor of the 2015 Detroit Auto Show. Until then, check out the official press release from Mopar.
