Driving Impressions

The Jeep Commander is remarkably responsive around town for a seven-passenger SUV, a trait we noticed while driving them in Los Angeles and Philadelphia. Its rack-and-pinion steering feels more precise than in many truck-based SUVs. Driving in rush-hour traffic reveals the Commander to be quicker, better balanced, and a little more conducive to aggressive driving than the average truck-based SUV, and far more so than its appearance suggests.

Still, the Commander is a tall and heavy and it suffers from copious body lean during heavy braking and in turns. When driving a Commander, you'll want to slow down more for turns than in most vehicles. Many car-based SUVs offer more stable carlike ride and handling characteristics than the Commander, and better fuel economy, too.

The Commander's 4.7-liter V8 engine delivers good throttle response around town. Punching the throttle signals the automatic to kick down into the lower of two second gear ratios to supply greater acceleration. Otherwise, a taller ratio with a smoother upshift is used. The effect is an energetic surge when you call for it, and a sense that you can control the transmission with your right foot. All in all, the 4.7-liter V8 is a fine all-around performer, and it can tow a healthy 6,500 pounds. Fuel economy estimates are 14 mpg city and 19 mpg highway with 2WD and 13/18 with 4WD. The 4.7 offers the additional advantage of Flex-Fuel Vehicle (FFV) capability, meaning it can run happily on gasoline or up to 85 percent ethanol (E85).

Those who plan to tow heavier loads, up to 7,400 pounds, should opt for the 5.7-liter V8. The changes made to the second generation of the reborn Hemi make it more powerful and responsive than ever. With it, the Commander pulls strongly from a stop and keeps accelerating as long as you have your foot in the throttle. It?s not quite as peppy as it is in the Grand Cherokee, but that?s because the Commander weighs, on average, about 300 pounds more. Thanks to the Multi-Displacement System, which shuts down four cylinders under light load conditions, the Hemi gets almost the same fuel economy as the 4.7-liter V8, with ratings of 13/19 mpg with 2WD and 13/17 with 4WD.

The 3.7-liter V6 uses the same electronic throttle control as the V8s, but its EPA ratings are only 15/20 mpg with 2WD and 14/19 with 4WD. Given the little gain in fuel economy and considerable power limitations, we would not recommend the V6.

On the highway, the Commander is a notably smooth and comfortable cruiser. Jeeps are not the most aerodynamic vehicles in the world, but wind and tire noise seem unremarkable, well within the range of the average SUV and something less than in bigger, square-bodied truck-based 4X4s. It is easy to maintain a conversation using normal tones of voice, and easy to imagine this would be a fine vehicle for cross-country touring.

The advanced Quadra-Drive II system and a 2.72:1 low-range gear gives the Commander excellent off-road capability, something we learned on rocky forest trails in the Pocono Mountains. This system supplies lots of traction, and the Commander has quick steering that makes it maneuverable in tight quarters.

The Goodyear Fortera tires, with their all-terrain tread, proved their worth as traction devices and suspension components, helping to soak up the lumps from rocks and logs, and maintaining a grip clearly enhanced by the Commander's electronic traction control.

Ground clearance is sufficient to negotiate rocky terrain, but challenging trails will create a few clangs and clunks when the underbody hits rocks and such. We found the Commander capable of going anywhere it will fit. The limitation would come if the Commander were used to cross steep, narrow gulches that call for extreme angles of departure because its longer body has more rear overhang than a Grand Cherokee. Nonetheless, for most people, there is probably more rough terrain capability built into the Commander than they will ever need or use.
