2009 Buick Enclave CX AWD

Adding the full-time all-wheel-drive system to the 2009 Buick Enclave CX AWD reduces fuel economy to 16/22 mpg, but provides extra traction on slippery roads. The system comes with a limited-slip center differential, but is not meant for real off-roading. This midsize crossover SUV gets its power from a 3.6-liter DOHC V6 with variable valve timing (hence its somewhat decent fuel economy) and delivers 275 hp and 254 ft-lbs of torque. A 6-speed shiftable automatic is the only transmission.

Emphasis here is on passenger comfort. Front- and second-row legroom numbers max out at 41 and 37 inches. The SUV seats seven with second-row bucket seats, or eight with an optional bench. The second row slides back and forth 3 inches and also flips up for access to the third row. Both rear rows fold flat, expanding the 18.9 cubic feet of cargo room to 116 cubic feet. Second-row passengers get their own climate control. The cargo area features several compartments, a power liftgate, and an intermittent wiper. A roof rack adds more storage space.

Full power accessories include power front seats (6-way driver's and 2-way passenger), heated mirrors, remote entry, a trip computer, Bluetooth, and wheel-mounted cruise and audio controls for the 6-speaker CD/MP3 player. A trial period of satellite radio is also standard. Leather upholstery is complemented by the leather and wood interior trim. The requisite six cupholders, security system, tilt and telescopic steering, tachometer, compass, and temperature readout are also included.

On the safety front, the 2009 Enclave CX AWD features 4-wheel disc and ABS brakes, dual front-side and side curtain airbags for all rows, traction and stability control, front and rear stabilizer bars, rollover mitigation, and 18-inch alloy wheels with all-season tires. A tire monitor, automatic xenon HID lamps, foglights, and an auto-dimming rearview mirror are all standard. Available options include parking sensors and a camera, folding side mirrors, a navigation system, remote start, and a sunroof.
