Special Car, auto, cars, vehicles

Under the hood, a DOHC 3.6-liter V-6 delivers a sturdy 275 horses through a six-speed automatic and, on our top-model CXL test car, optional all-wheel drive. For relaxed motoring, the powertrain feels up to the job, revving with a pleasing note and cruising with refinement. Unfortunately, the six has to move around a whopping 5077 pounds, a curb weight topped in our test only by the Godzilla-size Land Cruiser. Climbing steep, wriggling Highway 18 to Lake Arrowhead, the Enclave strained (a V-8 is said to be coming in a year or two). Shifting with the electric manual selector helped-and made driving through our handling loop more fun-but the pushbutton is inconveniently (and almost discreetly) mounted on the shift column.

The Enclave radiates a similar "I'm a limousine, not a plaything" character when you leg it. The variable-effort steering telegraphs little in the way of tire information, the engine turns coarse, and the sheer, shifting mass constantly hints that you should be looking for thrills elsewhere-though, in fairness, the Enclave remains poised and holds its line through turns.

The spacious, well-insulated interior is dressed in neatly tailored leather, camphor burl wood trim, and copious electronic conveniences. Worthy of special mention are the brilliant SmartSlide second-row captain's chairs that easily flip completely out of the way for access to the rear bench. This is a cabin worth fighting to ride in.
