The 2LT model gets swankier with a new luxury package that brings heated, 10-way-adjustable power seats with memory to the table, as well as a Bose Premium speaker system, and auto-dimming interior and exterior mirrors. The topline LTZ model gets even more goodies, including 12-way adjustable perforated leather heated seats with memory, Centerpoint Surround Sound Bose speaker system, brushed metal steering wheel trim, "Chevrolet" embossed sill-plates, chrome accents on the sides of the truck, a new rear fascia with more chrome accents and a trailer hitch cover, and new 20-in. chrome wheels.

On the outside, the LTZ model will get a new White Diamond Tricoat paint option, while the whole lineup will get Inferno Orange paint to replace the Sunburst Orange paint option on the previous model year. Dark Brahma Jewel paint will be available in limited quantities toward the end of the model year.

The Z71 off-road package -- with its beefier suspension, big tires, and auto-locking differential -- picks up body-color mirrors and door handles, and a chrome grille insert up front. Inside, Titanium and Cashmere are added to the list of interior colors.

Chevrolet has also gotten serious about safety in its trucks, and the Avalanche is no exception. It comes standard with driver and passenger front airbags, standard side-curtain airbags that stay inflated longer to protect in rollover accidents, a tire-pressure-monitoring system, and the StabiliTrack stability control system with dedicated rollover mitigation technology. The Avalanche also has sensors mounted all around the truck to detect an imminent collision and give the safety systems advanced notice. This system allows the seatbelts to lock before a rear-end collision and keep occupants in place. All models come with GM's OnStar service free for one year, while LT and LTZ models also get the Directions and Connections plan for one year free which features turn-by-turn directions.

Pricing for the 2009 Avalanche starts at $35,910 for the base LS model. The LT model starts at $36,780, while the top-level LTZ model starts at $44,100. The gasoline-only 5.3L V-8 gets an EPA-estimated 14 mpg city and 20 mpg highway, while the FlexFuel 5.3L V-8 gets 10 mpg city and 15 mpg highway. The 6.0L V-8 gets 14 mpg city and 19 mpg highway.
