Commander Sport 2WD ($27,915) comes standard with a 3.7-liter SOHC V6, rated at 210 horsepower and 235 pound-feet of torque. The V6 is mated to a five-speed automatic transmission designed to balance performance and fuel economy. Also standard on Sport are air conditioning, AM/FM/CD stereo with six speakers, power windows, power heated mirrors, front bucket seats with adjustable lumbar, ParkSense (which detects objects behind the vehicle while backing up), liftgate glass that flips open by remote control, all-terrain tires on 17-inch cast aluminum wheels, tire-pressure monitor, a full-size spare tire, and cruise control with switches on the steering wheel. Door handles, which were black last year, are body color for '07.

Commander Sport 4WD ($29,915) adds Quadra-Trac I, an automatic full-time all-wheel-drive system enhanced by electronic traction control.

A 4.7-liter SOHC V8 is available on Sport as part of an option package. It is rated 235 horsepower and 305 pound-feet of torque. This engine also comes with a five-speed automatic, but a more heavy-duty unit with a split second gear that provides a shorter ratio on kick-down than on up-shift.

Limited 2WD ($36,025) comes standard with the 4.7-liter V8 and HD transmission, plus a wide array of comfort and convenience features, including automatic climate control; leather upholstery with perforated inserts; leather-wrapped steering wheel; Boston Acoustics sound system with six-CD player, MP3 playback, and Sirius Satellite radio; power adjustable, heated front seats; power adjustable pedals; rear-seat heat, ventilation; power sunroof; remote starter; rain-sensitive windshield wipers; SmartBeam automatic headlights; universal garage door opener; and a security system. Limited can be distinguished by its chromed grille and exterior chrome accents.

Limited 4WD ($38,645) has Quadra-Trac II, a full-time active four-wheel-drive system that includes a two-speed transfer case (so you can select a lower gear range for crawling through seriously rugged, muddy, or sandy terrain; or neutral for towing); plus electronic traction control.

Optional on Limited is the 5.7-liter Hemi V8 (again, as part of a larger package), producing 330 horsepower and 375 pound-feet of torque. The Hemi features potentially fuel-saving Multi-Displacement System (MDS) technology, which shuts down four of the eight cylinders under light-load conditions.

Optional with the Hemi is Quadra-Drive II ($795), Jeep's most sophisticated 4WD. Three limited-slip differentials (one in each axle and one between the axles) are electronically controlled, sending torque to the wheels, or single wheel, with the best traction.

The new top-of-the-line Overland ($40,510) comes standard with the Hemi and a trailer-tow group. It raises the interior plush factor with suede-trimmed leather seats embroidered with the Overland logo; leather-wrapped shift knob and grab handles; Berber floor mats; and woodgrain trim on the center stack, console, steering wheel (which is also leather-wrapped) and front door panels. Overland also adds conveniences, such as a power liftgate, ParkView reversing camera, GPS navigation, UConnect hands-free communications, and a cargo net. Outside, Overland is distinguished by Platinum-look trim and a unique wire-lattice grille.

Overland 4WD ($43,975) comes with Quadra-Drive II.

Other Commander options include rear-seat DVD player and engine block heater. An Off-Road Group for 4WD models adds skid plates and tow hooks. A Class III towing package is available with the V6, and a Class IV package with either V8. Additionally, many Limited and even Overland convenience features are offered as either options or part of option packages on lower-cost models.

Safety features that come standard include side-curtain air bags with a roll detection system deploy in case of rollover and/or side impact. Front air bags are the multi-stage type that deploy in stages according to the severity of an impact. The front seatbelts are equipped with belt pretensioners and constant-force retractors; be sure and wear them as they're your first line of defense in a crash. Anti-lock brakes are complimented with electronic stability control to enhance driver control. Brake Assist helps ensure maximum braking in panic situations, even when the driver mistakenly relaxes pressure on the pedal.
