The engine did not give us a lot of on-demand power while cornering, but the Grand Cherokee's all-wheel drive and suspension tech helped it perform well, limiting body roll and delivering an overall feeling of stability. The suspension showed a good deal of refinement, not only handling corners well but contributing to a comfortable ride on various road surfaces.
Around town and on the freeway the Grand Cherokee felt equally tractable, easy to maneuver in tight quarters and smooth riding at high speeds. The V-6 didn't deliver the passing power we would have liked, but it turned in reasonable fuel economy. We achieved a 19.5 mpg average, admittedly with a bias toward freeway and highway driving. The EPA rates it at 16 mpg city and 22 mpg highway. The V-8 dips down to 13 mpg city and 19 mpg highway.
Helping us out on the freeway was a blind-spot detection system and adaptive cruise control, two advanced features that show Jeep isn't afraid of technology. The blind-spot system worked well, lighting up icons in the side mirrors when cars were off the corresponding rear quarter. If we happened to hit the turn signal for that side, the system flashed the icon and sounded a warning note, useful in an SUV.
The adaptive cruise control let us set our speed and following distance for slower traffic. We were impressed when the radar locked on the slim profile of a motorcycle ahead, maintaining a comfortable following distance. This system is capable of bringing the Grand Cherokee to a complete stop.
The cruise control's radar is also used for a crash mitigation system that, when sensing an impending collision first gives an audible warning then activates precrash systems such as tightening seat belts. This system seemed to lack discrimination, occasionally sounding its warning for traffic or objects that weren't in our path. But it never went beyond the audible warning for false alerts.
As a standard feature in the Limited trim Grand Cherokee, the head unit has a colorful LCD on the center stack with a 30GB hard drive inside. Strangely, we did not have navigation in this vehicle. Jeep says that it will include some kind of Garmin GPS with the Grand Cherokee Limited at a later date. We have used the hard-drive-based navigation system that is supposed to be optionally available with the Limited trim. It shows traffic information and has the usual features we expect from a navigation system in a luxury vehicle.
With the hard drive, we could store quite a bit of music in the Grand Cherokee, either by ripping it from CDs or transferring from USB drives. Jeep puts some tools for managing files on the hard drive in the vehicle's interface, and offers a good browser to select music by album, artist, genre, or individual track. Although not optioned on our vehicle, iPod integration is available and uses the same interface.
What really impressed us was the quality of the audio from the car's 10-speaker system. Unbranded, the system uses a 506-watt amp and delivers excellent detail all around. The sound is as well-balanced as from any premium car-based system, with controlled bass and pleasant highs. Vocals come through clearly, and we found it overall a very enjoyable listening experience.
Having that good-quality audio system is especially important considering our car's optional rear-seat entertainment system. The ceiling-mounted LCD showed the typical problem of blocking the view from the rearview mirror when down. It only shows a single source, as opposed to some of the new dual-source screens showing up in minivans lately. But along with DVD playback, it also shows satellite TV. This limited offering from Sirius brings in shows appropriate for children from Nickelodeon, Disney, and Cartoon Network.
In other Chrysler company cars using a version of this head unit, such as the Dodge Challenger, we complained that the voice command button was too far from the driver. The Jeep Grand Cherokee not only puts the voice command button on the driver side of the head-unit bezel but also puts a button on the steering wheel.
This voice command system proved very accurate in our testing and also allowed for dialing by name from a paired cell phone's contact list. The Bluetooth phone system also appears to have the capability of reading out received text messages, but we were not able to test that capability.
The 2011 Jeep Grand Cherokee has come a long way over the decades, as evidenced by this vehicle's advanced cabin tech. Its stereo, Bluetooth phone system, and navigation are all very feature-rich, but what helps push it over the top are the extras, including the rear-seat entertainment system, driver assistance features, and an available wireless hot spot network.
For performance tech, its off-road systems show excellence in features and capability. However, the engine choices and transmission are not as advanced as they could be, and they show it with moderate power and fuel economy.
Where the Grand Cherokee could use some real refinement is in the cabin tech interface, which looks out of place among the general interior fit and finish. And though the vehicle offers the practical interior space and ergonomics we would expect in an SUV, its rear looks too generically boxlike. However, its front end does a good job of proclaiming its Jeepness.
