Safety features fitted on all Mountaineers at no extra charge include dual-stage front airbags, electronic stability control with rollover sensors, antilock brakes with brake assist, LATCH child safety seat anchors, and a tire-pressure monitor. Optional on Convenience and Luxury ($795) and standard on Premier is a Security group, with reverse sensing system and side curtain airbags for front and second-row seats. We recommend getting them. Wear those seatbelts because they're your first line of defense in an accident.

Walkaround

In every measure, be it by the tape or visually, the distinctions between the 2006 Mountaineer and 2005 Mountaineer are modest. So if you buy a 2006, don't count on your neighbors rushing over to check out the newest on the block.

For 2006, the trademark waterfall grille returns, only sans the thin border, with free-standing, vertical bars and a robust Mercury emblem front and center. Headlights are unchanged, an offbeat mix of curving lines and sharp angles. The front bumper holds rectangular fog lamps, a sectioned lower air intake and, new for 2006, a satin-finish, aluminum cross bar running the width of the grille. Fenders wear the same, edgy, machined-metal look.

Side view changes only in dimensions, with the wheelbase (the distance between the front and rear wheels) shrinking by 0.1 inch from the '05, and overall length (measured bumper to bumper) growing more than two inches. Cladding covers the lower door panels. A wide C-pillar separates the rear side doors from the rear quarter windows. Mercury redesigned the side mirrors for better aerodynamics. The optional powered running board tucks away beneath the rocker panel, extending only when the doors are open. The tires don't change in diameter but the sidewalls are shorter and the diameter of the wheels is larger: The standard 17-inch and optional 18-inch wheels replace the '05's 16-inch and 17-inch wheels respectively.

The liftgate is two-piece, with the glass hinged separately. This lets you load groceries through the window, which is useful.

The taillights wear clear lenses, with the requisite red glow appearing when brakes are applied or running lights turned on.

Interior Features

While the 2006 Mountaineer's exterior may be deja vu, the interior is anything but, right down to the deletion of the embroidered Mercury crest in the top-most element of the leather-trimmed seatbacks. And although some of the changes are for the better, a couple are so counter-intuitive that the carmaker has already announced plans to redo them.

Instruments have been pared down to the essentials (gone are oil pressure and voltage readouts, leaving speedometer, tachometer, fuel and coolant) and re-organized within a recessed pod surrounded by a satin-finish, metallic ring. It's a less-busy arrangement, but given the Mountaineer's workhorse capabilities, as evidenced by the V8 AWD's three-ton tow rating, we miss the omitted gauges. The dash is cleaner, though, with attractive, low-key, metallic accents.

The stereo and climate controls in the center stack have been updated to accommodate the screen for the optional navigation system, yielding larger, more finger-friendly buttons. The results here are mixed. The stereo and navigation system operate on separate power supplies, so you can have a map displayed without having the stereo on. That's not true of all navigation systems, including those from Mercedes. But sadly, the stereo's tuning function remains buried beneath a sequential rocker switch, forcing you to wait while it scrolls up or down through the frequency band to find any station other than one of the presets. The navigation system screen could be larger, but the information it provided was adequate and accuracy was above average.

The front seats are comfortable, with adequate thigh support and bolsters. Overall, passenger roominess is competitive for the class. The Mountaineer offers comparable headroom in the front seats as the the 2006 GMC Envoy and Nissan Pathfinder, trailing them by less than an inch; front-seat legroom betters the Envoy by an inch and equals the Pathfinder; front-seat hiproom is almost identical.

Second-row headroom and legroom is comparable to the Envoy, but the Mountaineer offers significantly 2.5 inches more legroom than the Pathfinder's second row offers, a noticeable difference. However, the Mountaineer doesn't have nearly as much second-row hiproom as the Envoy and Pathfinder do. The middle-row bench seat has full seatbelts for three but head restraints for only the outboard passengers.

The third-row seats in the Mountaineer are significantly roomier than those in the competition's, with nearly three inches more legroom than Envoy and more than six inches over the the Pathfinder. Headroom and hiproom are comparable. The third row is a bench seat with minimal padding and fixed-height head restraints, which loom large in the back window; they do collapse, but only by tugging a loop hanging out the backside. Much better are the optional third-row seats that can be power-folded via two rocker buttons in the left rear quarter panel, directly below a thoughtfully provided button for the power central locking.
