The Commander has a choice of V6 and V8 engines available. The mid-level 4.7-liter V8 seems an excellent choice, with responsive acceleration performance for working through traffic and fuel economy just slightly lower than the 3.7-liter V6. The 5.7-liter V8 Hemi is a good choice for buyers who tow trailers of up to 7,400 pounds. Two- or four-wheel drive versions are optional. It comes in three trim levels: Sport, Limited, and Overland. Safety features include side-curtain air bags, front air bags, seatbelt pretensioners, anti-lock brakes, electronic stability control, and brake assist.For 2007, the ultra-luxury Commander Overland joins the lineup, with more amenities. Several new features are also available such as: a rearview camera, a power liftgate, a remote starter, and active turn signals.
