2014 Jeep Grand Cherokee EcoDiesel

Choose Your Own Adventure... But Choose Wisely
Jeep has got you covered. We can say this without even having to know what it is you want, because there's hardly an option or configuration that you won't find in the 2014 Grand Cherokee. There are three different engines, three different four-wheel-drive systems (plus rear-wheel drive), four different trim levels - not counting SRT - two different suspension setups and five different settings for various off-road terrain conditions. If you happen to check the box for Quadra-Lift, you'll also have five different ride-height settings for the driver-selectable air suspension.
As you might expect with so many customization possibilities, the way a buyer checks the options sheet can have a profound effect on the final product and its capabilities, to say nothing of its price. Nowhere is that more true than with the Grand Cherokee's choice of engines, with the brand-new 3.0-liter EcoDiesel V6 stealing the spotlight from the still excellent gasoline-fueled 3.6-liter Pentastar V6 and 5.7-liter Hemi V8 powerplants that carry over from last year. No matter which engine you choose, though, it will be paired up with Jeep's new standard eight-speed automatic transmission from ZF. This, ladies and gentlemen, is very good news indeed.

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.

Jeep Renegade sales being held due to powertrain issue [UPDATE]

UPDATE: An unnamed FCA US source has clarified to Automotive News that while there is a software issue, it does not concern the transmission. The Jeep Renegade appears to be facing early software problems that are similar to the ones at the introduction of the Cherokee a few years ago. The issue is keeping the brand's latest compact crossover away from dealers until the situation can be resolved. The fault reportedly deals with the software controlling the Renegade's nine-speed automatic transmission. FCA CEO Sergio Marchionne briefly talked about what was happening in an interview with Automotive News. "I'm having a very bad engineering day," he said. "It's a combination of attributes of that vehicle that is making my life horrible." The company boss predicted at the longest it could take until mid-June to fix things. Through April, Jeep has sold 5,157 Renegades, including 4,214 of them in that month alone. Autoblog reached out to an FCA US spokesperson to learn more about the software problem, but the company had no comment. Getting the software right to control the nine-speed automatic plagued development of the Cherokee. The issues delayed the model's launch in 2013, and the company was still releasing improvements for some vehicles this year.
