Take a roomy luxury crossover and add full-time AWD, and you get the 2009 Buick Enclave CXL AWD. Along with a limited-slip center differential, the AWD system gives this midsize crossover SUV more traction in tough driving situations, but is not intended for off-road use. The 3.6-liter DOHC V6 and 6-speed shiftable automatic deliver 275 hp and 254 ft-lbs of torque and offer a towing capacity of 4,500 pounds (with the optional tow package). Fuel economy averages 16/22 mpg. The crossover rides on a Macpherson strut front and multilink rear suspension and gets larger 19-inch alloy wheels with all-season tires.

Other upgrades from the CX AWD include leather upholstery, heated front seats, and more power settings for the front seats (8-way and 4-way respectively). Driver's memory settings, a garage opener, and four power outlets are also standard. These join the full power setup, wheel-mounted cruise and audio controls, keyless programmable entry, front and rear wipers, front and rear climate control, leather and mahogany trim, and power liftgate. The CD player features satellite radio and an MP3 input jack. Bluetooth allows for hands-free phone use. A trip computer, tachometer, temperature readout, and compass provide added information for the driver. Remote start, a navigation system, and a sunroof are useful options.

The 2009 Enclave CXL AWD seats seven or eight in three rows, depending on whether you stick with the standard second-row bucket seats or choose the optional bench. Captain's chairs are also available. The second row flips and folds, reclines, and moves 3 inches back and forth for easier third-row access. Both rear rows fold flat for up to 116 cubic feet of cargo space. A standard roof rack adds more capacity. Receiving five stars in all crash tests except rollover (four stars), the Enclave CXL AWD features traction and stability control, front and rear stabilizer bars, rollover mitigation, and 4-wheel disc and ABS brakes. The dual-stage dual front-side airbags have passenger sensors, and side curtain airbags are standard for all three rows. Automatic headlights with xenon HID lamps light the way, supplemented by foglights and daytime running lights. An auto-dimming rearview mirror, tire monitor, and OnStar are also standard. A rearview camera and backup sensors can be added.
