2010 Jeep Commander

HEMI V8 Engine
This smooth and muscular powerplant, named for its '50s high-performance ancestors, is an always-eager sweetheart, electronically tethered to your throttle foot. Despite its size, power and simple OHV (pushrod) valvetrain, it delivers EPA fuel economy ratings of 14 miles per gallon city and 20 miles per gallon highway, due to its Multi-Displacement System (MDS), which transparently disables four of its eight cylinders at light loads to conserve fuel.

Quadra-Drive II Active Full-Time Four-Wheel Drive
Jeep's most advanced four-wheel-drive technology, Quadra-Drive II uses front and rear Electronic Slip Differentials (ELSDs) to transfer up to all available torque to any individual wheel with traction. Standard with the HEMI V8 and available with the other two engines, it is as capable in difficult conditions as any system, either on or off the road.

Jeep's first three-row vehicle provides good two-row room, but we wouldn't want to spend much time in that way-back third row with just 28.9 inches of legroom and 35.7 inches of headroom. Behind it are grocery hooks and a bin with a clever three-way lid, but little cargo capacity with the seatbacks up. Echoing the exterior's "bold, rugged, constructed" theme, the base Commander cabin has cloth seats and a nicely textured upper dash. Sixteen Allen-head screws retain eight large, round air vents, while simulated Allen heads encircle the gearshift knob and steering wheel hub. The second row splits 40/20/40, the third row 50/50, and both fold flat for cargo.

While the Commander's shape is cinder-block blunt, much wind-tunnel effort has been devoted to reducing aerodynamic drag for fuel efficiency and interior quietness. The big, blocky outside mirrors, for example, are virtually invisible to the wind, according to the vehicle's chief designer. The roof is raised 3.15 inches, with the upturn beginning over the second row to provide more headroom. The roof-rack stanchions resemble buttress-style bridge supports, and five large simulated Allen screws appear to hold on each trapezoidal fender flare. The uplevel Limited wears chrome on its signature seven-slot grille, front fascia, body-side moldings, roof-rail crossbars and the two large liftgate grab handles that assist access to rooftop cargo.

Chrysler's modern HEMI V8 gets all the attention, but it is costly and, despite the best efforts of its fuel-saving MDS, less fuel-efficient than its more affordable stablemates. Potential buyers should test drive and consider the more frugal V6, depending upon their anticipated towing and hauling needs. The HEMI is more glamorous and more fun when you tickle its throttle, but you don't need 357 horses to cruise around town on level ground.
