2009 Chevrolet Avalanche LTZ

The top-of-the-line Avalanche LTZ offers a number of features not available in other Avalanche trims, including heated and cooled leather-appointed front bucket seats, a Bose Centerpoint surround-sound system, Rainsense front wipers, 20-inch polished aluminum wheels, and an Autoride suspension, which continually and automatically varies the shock-damping rate, depending on the road surface, steering angle, and other factors, to maximize handling and passenger comfort. In addition, a rear self-leveling feature helps maintain the appropriate rear suspension level when fully loaded or pulling a trailer. Other standard features for the rear-wheel-drive, six-passenger LTZ include a leather-wrapped multifunction steering wheel, power-adjustable pedals, dual-zone climate control, a remote starter, and an Ultrasonic Rear Parking Assist, which uses beeps and flashing lights to alert drivers when stationary objects are within 8 feet of the vehicle when backing up.  

A 5.3-liter Vortec V8 engine generating 310 hp and 335 lb-ft of torque powers the LTZ, but drivers can opt for a 6.0-liter V8 producing 366 hp and 376 lb-ft of torque. Both engines come equipped with Active Fuel Management, which shuts down four cylinders when they're not required to conserve fuel, and link to a six-speed Hydra-Matic automatic transmission. Such features as GM's StabiliTrak electronic stability program, an automatic locking rear differential, roof-mounted luggage-rack side rails, and chrome-capped power-folding heated exterior mirrors with auto-dimming on the driver's side also come standard.
