The Jeep Liberty Sport has been redesigned for 2008 to look even more macho than its predecessor. The longer, wider, squarer (and cheaper) Liberty gets an imposing front profile, some notable cabin tech options including Chrysler's MyGig system, and an available Sky Slider roof giving all passengers an open-top driving experience. While the Liberty Sport comes with two four-wheel drive options, our test car was the entry-level, two-wheel drive model, meaning that our weeklong review with the car was strictly confined to the road.
Test the tech
Regular readers of CNET Car Tech will know that this section is usually dedicated to evaluating a unique or outstanding technical feature of the review car. With the Jeep Liberty Sport, this was easier said than done as the car came with very few onboard gadgets. Its saving grace, however, was a 110-volt AC electrical outlet forward of the rear seats, which gave us the opportunity to bring in our own external devices. In many ways, we figured, having a generic electrical outlet is better than any number of onboard gadgets as it allows occupants of the car to bring their own choice of gadget on the road. With this attitude, we racked our brains and ransacked the CNET offices to come up with the most inventive Car Tech applications we could find. Having found a coffee maker and a popcorn machine, we resolved to use an extension cord to simultaneously plug both into Jeep for a delicious--if slightly mismatched--mid-morning snack.
The first obstacle we ran into was the fact that every extension cord we could find had a three-pin plug on it, whereas the Jeep's AC outlet has only two pins. This not only limited the number of extension cords we could plug, but also the number of devices that we could connect directly to the power supply. We eventually found a two-prong extension cord, and set about connecting our kitchen gadgets. To start, we decided to try to use the Liberty's electrical supply without the engine running, and then switch the engine on if and when needed. To activate the AC outlet in the rear of the vehicle, drivers must first press a button on the dashboard mounted beneath the stereo.
With this done, we plugged in the extension cord and then the popcorn machine. The fan whirred for about 3 seconds and then the machine died. We noticed the yellow light on the dash-mounted AC activation button had turned off, so we reached over and reset it. The popcorn machine whirred again and died. We tried the same thing with the coffee maker, which--likewise--turned on for a few seconds and then died. Blaming it on lack of electrical charge, we turned on the Liberty's engine and tried again. Once more, the devices turned on briefly and then turned off. Thus thwarted, we decided that the battery needed extra charging. We took the coffee maker and popcorn machine out of the car, jumped in the driver's seat, and drove the Jeep on a 100-mile roundtrip. We really wanted our Jeep snacks.
On our return, we plugged the devices back in, resolving to have popcorn and coffee for lunch instead of as a mid-morning snack. To our dismay, however, the same thing happened again: neither of the devices would run for more than a couple of seconds without cutting out. We abandoned our mobile kitchen idea and set our sights a bit lower. Was the Jeep's electrical outlet good for anything? We tapped the cell phone department for a handset that needed charging and went to find out if the Jeep could charge something that required less power. An hour and a half later, we check on our phone and it was fully charged. It appears that the Jeep's AC outlet can be used to power low-current devices even with the engine off, but cannot be used for more power-hungry gadgets.
In the cabin
Jeep is not known for the luxury or technology content of its cabins, and the Liberty Sport does nothing to change this reputation. The Liberty's interior presents the driver and front passenger with bare, rugged, wipe-down-able materials on the dash, doors, and central console. Similar to the Jeep Commander, the Liberty has a flat slab of a dashboard punctuated by a series of molded plastic storage compartments. While we can just about live with the two-tone plastic trim, we are less enthusiastic about the strips of silvery faux-metallic plastic that frame the Liberty's central stack: Whether this design cue was intended to add a little pizzazz to the cabin or to give it a sporty feel, it failed on both counts. One of the most noteworthy additions to the cabin of the 2008 Liberty (but not, alas, on our test car) is the availability of the Sky Slider full-length, open-canvas roof made from reinforced-acrylic cloth, which gives both rows of passengers a full view of the heavens and adds an extra $1,200 to the price tag.
