2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

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.

Ram 1500 diesel overlander, off-road Jeep Wrangler show present and future of Mopar

Ram and Jeep both have some heavily customized off-roaders for SEMA this year. The Ram is a 2020 1500 Rebel with the diesel engine and an overlanding theme, and the Jeep is a 2020 Wrangler Unlimited with a general off-road theme. Each features loads of Mopar accessories, and, in the case of the Ram, accessories from other companies. They both have a few parts that haven't made it to market yet. 2020 Ram 1500 Rebel View 16 Photos 2020 Ram 1500 Rebel OTG The Ram 1500 has the suffix of OTG, which stands for off-the-grid. It's designed to be an overlanding vehicle perfect for getting you far away from civilization and still have your needs taken care of. As such, the new EcoDiesel with its strong fuel economy and large amounts of torque is a good engine choice, and the Rebel has plenty of rugged style to begin with. That style is augmented by some special concept Mopar parts such as a high-flow grille complete with flow-through Ram block letters, a la the Chevy "Flow Tie," and steel bumper with a retro-fitted Power Wagon winch. Another concept part is the intake snorkel. Dodge also dug into the existing catalog of Ram parts and added the base Tradesman's vinyl flooring for easy interior cleaning, as well as the Tradesman's rear bumper that doesn't have cut-outs for exhaust. The exhaust was then tucked away behind the bumper, giving the truck a better departure angle. Many ready-to-purchase accessories have been added to the Ram 1500 OTG, too. From the Mopar catalog comes off-road lights, rock rails, wheels and bolt-on fender flares. The utility rack, basket and tent all came from Yakima. A roof-mounted solar array along with sliding cooking areas and bed-mounted cooler all come from Dometic. A representative from Dodge also showed how the split tailgate can be used as an easily accesible place to have fold out cooking or table space. 2020-jeep-wrangler-mopar-accessories-01 View 4 Photos 2020 Jeep Wrangler Unlimited While the Ram has parts from all around the aftermarket world, the Jeep Wrangler Unlimited has been outfitted entirely with Mopar parts. And most of those parts are already available, with two exceptions. On one side of the truck, Jeep is showing off some concept mesh covers for its tube-doors. The idea behind them is that they still allow for plenty of air flow, but help keep shrubbery, mud clods and other things from getting in. They're also simple to install or remove, since the slide on and zip up.
