Each electronically activates the appropriate combination of 12 different powertrain, brake and suspension settings to optimize traction and ground clearance. The Selec-Terrain system has five driver-selectable terrain modes that correspond to potential conditions: Sand, Mud, Auto, Snow or Rock. It can come down another full inch when parked to allow easier entry, exit and loading. The Quadra-Lift air suspension raises the Grand Cherokee’s ground clearance by 3.9 inches from its normal height to 11.3 inches for off-road use or down 0.6 inch for high-speed aerodynamic improvement. Quadra-Trac I provides full-time all-wheel drive Quadra-Trac II adds a two-speed transfer case with a low range and Quadra-Drive II builds on that by adding an electronic limited-slip differential. Preliminary estimates put Hemi mileage at 14/22 mpg city/highway (4×2) and 14/20 mpg (4×4), but the diesel is expected to turn in a stunning 22/30 mpg (4×2) and 21/28 mpg (4×4) with a range of more than 730 miles.Īs with the current Grand Cherokee, the 2014 model boasts three optional four-wheel-drive systems, an available adjustable air suspension and a traction management system. Both the EcoDiesel and the Hemi are tow-rated to 7,200 pounds in 4×4 versions or 7,400 pounds with rear-wheel drive, but the diesel’s advantage will be fuel economy. All engines are now teamed with Chrysler’s increasingly common 8-speed automatic transmission, replacing the earlier six-speed. Now added to the mix is a new 3.0-liter EcoDiesel V-6, making only 240 hp but churning out a huge 420 pounds-feet of torque. Two engines are carried over from 2013: a 3.6-liter Pentastar V-6 making 290 horsepower and 260 pounds-feet of torque and a 5.7-liter Hemi V-8 pumping out 360 hp and 390 pounds-feet of torque. The biggest changes to the 2014 Jeep Grand Cherokee over the previous model are mechanical (click here to compare 2013 to 2014 models). I tested multiple trim levels and all four available engines, including the high-performance SRT Grand Cherokee. The 2014 Grand Cherokee is a subtle refresh, with money spent simply on what needed improvement, and the result is now one of the best vehicles Jeep has ever made. Now Jeep is presenting a refreshed 2014 Grand Cherokee even as the old one is still propelling the brand to record sales numbers, and the problem is this: How do you improve on what is already a good thing? Thanks in advance for any suggestions or information about what could be causing this problem and or what to fix.Chrysler’s 2011 Jeep Grand Cherokee pretty much saved the company’s bacon as it struggled to pull itself out of a demoralizing bankruptcy. I asked him about the size of the tires and he said it has 20-inch rims with OEM size tires.ĭoes anyone have any suggestions of what should be checked for problems that could cause these symptoms? And where he works is an area with a major fast road that is often used. He is very unhappy with the way this vehicle performs, and says it is very hard to use to pull out onto a highway with. I asked him if it has sport mode and he said yes, but if he uses that it winds out first with way too high RPM's and then slams shifts into second and practically gives you whiplash. He said it is always shifting into too high of a gear to try to get the maximum gas mileage, and has no torque. Someone local has a 2014 Jeep Grand Cherokee Summit with the 6-cylinder engine (not a hemi), and 8 speed automatic transmission. 2014 Jeep Grand Cherokee engine / transmission ?
