Press Release :
The 2007 Chevy Avalanche is the next generation of the industry’s most flexible utility vehicle. It combines the passenger-comfort attributes of an SÚV with the cargo capability of a truck. It is based on GM’s new, full-size SÚV platform, which features more power with §egmènt-leading fuel economy and flex-fuel capability; a sharper, more precise driving feel; increased interior refinement; and improved quietness.
Avalanche delivers a 360-degree safety system of occupant protection and crash-avoidance technology that demonstrates GM’s commitment to providing world-class safety, including available head curtain side air bags and standard StabiliTrak stability control system with new rollover mitigation technology.
The 2007 Avalanche is available in LS, LT and LTZ models, with 2WD and 4WD. The standard powertrain includes an efficient 5.3L V-8 with Active Fuel Management technology that seamlessly switches from eight-cylinder to four-cylinder operation to save fuel. Later in the model year, an all-aluminum 6.0L V-8 with Active Fuel Management and variable valve timing (VVT) will be available. Several available engines allow Avalanche to run on E85, a renewable fuel made of 85 percent ethyl alcohol (ethanol) and 15 percent gasoline.
Returning to Avalanche is the popular Z71 Off Road appearance package. This optional package takes the vehicle’s aggressive look to the next level, with larger recovery hook openings, larger, more prominent fog lamps and specific grille texture and platinum chrome grille trim. Eighteen-inch wheels and tires also are part of the package.
Enhanced flexibility
Avalanche’s unparalleled flexibility enables it to function as an SÚV, truck or both, thanks to the unique Midgate. Pioneered on the first-generation Avalanche, the Midgate opens to extend the cargo-carrying capability from the cargo bed’s 5.3-foot-long (1.6 m) length to 8.2 feet (2.5 m). The rear seat must be folded to achieve maximum storage capability; with the rear seat up and the Midgate closed, Avalanche has room for up to six passengers.
When the Midgate is open and the rear seat is folded flat, Avalanche can carry 4-foot by 8-foot (1.2 m by 2.4 m) sheets of plywood with the tailgate closed. Storage compartments alongside the cargo box provide ample and lockable storage. The storage compartments also have drains, so they can be filled with ice and used as coolers. A three-piece rigid cargo cover with interlocking panels also is available.
New features on the ’07 model enhance Avalanche’s flexible attributes and reflect customer feedback, including a central-locking tailgate, remote vehicle starting system and cargo cover retaining straps. Also, the new tailgate is spring-loaded to reduce the effort needed to open or close it.
Avalanche also offers convenient articulating running boards, which blend smoothly with the vehicle’s design. They automatically move downward and outward when the doors are opened, providing a lower step-in height.
Efficient performance
Avalanche is powered by a new Gen IV small-block V-8 family that delivers more power than comparable powertrains in previous models. Standard on 2WD models is an iron-block Vortec 5.3L V-8 with 320 horsepower (239 kW)* and 340 lb.-ft. of torque (461 Nm)*, which offers Active Fuel Management. Two versions of the Vortec 5.3L Gen IV V-8 – including an aluminum-block version that is standard in 4WD models – are compatible with E85. The 5.3L aluminum-block V-8, standard on the 4WD Avalanche, delivers an estimated 310 horsepower (224 kW)* and 335 lb.-ft. (454 Nm)* of torque.
An all-aluminum 6.0L V-8 with variable valve timing (VVT), as well as Active Fuel Management is available on 2WD and 4WD models. It is rated at an estimated 366 horsepower (273 kW).* VVT helps optimize camshaft timing to improve low-rpm torque and high-rpm horsepower. The system is enabled by a unique dual-equal cam phaser – the industry’s first application of VVT on a mass-produced V-8 cam-in-block engine. The unique dual-equal phaser adjusts the camshaft timing at the same rate for both the intake and exhaust valves. A Hydra-Matic 4L70 electronically controlled four-speed automatic transmission is paired with the engine.
Contributing to Avalanche’s more efficient performance is improved aerodynamics. A more steeply raked windshield and smoother roofline improve airflow over the vehicle, while a dditional contributors to efficiency include a lower, wider front air dam, tighter tolerances and gaps between the fascias, lamps and grille openings, and improved front-end sealing that nearly eliminates air leak paths. These features all contribute to enhanced fuel economy and improved driving quietness, compared with previous models.
Interior refinement and convenience
The interior of the ’07 Avalanche represents a new level of refinement, comfort, quality and convenience. It is roomy and airy, thanks to a lower instrument panel and deeper windshield that improve outward visibility. Passenger space also is increased, including more shoulder space for rear passengers, which is packaged with the available roof-mounted head curtain side air bags with rollover protection for both seating rows.
Avalanche’s new front seats are designed to provide more comfort and easier entry/egress. Door pillar-mounted first-row three-point safety belts facilitate slimmer seat design, which helps increase cargo space behind the seats. Comfort has been enhanced with firmer foams, including more aggressive bolsters. The front-row seats have one-inch more aft travel than previous models. The rear seat is unique to the Avalanche and enables easy access to the Midgate system. The seat folds flat, allowing longer items to be carried between the cargo bed and into the rear passenger compartment.
Refinements throughout Avalanche’s spacious interior create an environment that exudes quality and precision. Flush-mounted accessories and controls, such as the climate control/radio center stack, create a seamless, ‘single unit’ appearance. Also, there are almost no exposed metal hardware or latches, as all models feature enclosing ‘close-outs’ around the seat bottoms and door sill trim plates. New comfort features include an upgraded HVAC system, and storage capability is improved with the §egmènt’s largest center console storage bin, a larger glove box and additional new storage compartments. Avalanche also offers a host of available convenience features, including:
Últrasonic Rear Parking Assist
Rearview camera system
Touch-screen navigation system
DVD rear-seat entertainment system with larger, 8-inch screen and enhanced features.
Avalanche also features an impressive new audio/navigation lineup, which provides quality entertainment and information. A new family of CD/MP3-compatible radios leads the audio lineup, with an enhanced DVD entertainment system that includes a larger, 8-inch screen (with in-dash loading). A new touch-screen navigation radio is available and incorporates the view monitor for the available rear-camera system.
Distinctive design
Avalanche’s all-new exterior, monochromatic design is leaner and more agile lòòking, with a more steeply raked windshield and smoother roofline accentuating the exterior length. Avalanche wears the new face of Chevrolet, with a large Chevy gold bowtie, centered on a twin-port horizontal grille. The body-colored grille surround is inset with an argent texture mesh. Fog lamps and headlamps feature jewel-like optics.
Avalanche’s front end styling reflects its capability. It includes the fast-rake windshield; a bulging power dome hood; a prominent new fender design with integrated wheel flares; a distinctive new grille and headlamps; and a full-wrap fascia. The wraparound fascia eliminates the conventional bumper-to-body gap and is one of the numerous attributes that gives the Avalanche a more refined look. It also enhances aerodynamics. There also is a new family of 17-inch and 20-inch wheels. Seventeen-inch wheels and tires are standard, with 20-inch factory-installed wheels available (standard on LTZ). The larger wheels fill Avalanche’s wheel houses, giving the vehicle a confident stance.
Avalanche is offered in nine exterior colors: Greystone Metallic, Dark Blue Metallic, Sport Red Metallic, Bermuda Blue Metallic, Black, Summit White, Gold Mist Metallic, Sunburst Orange Metallic and Silver Birch Metallic.
New full-size SÚV foundation
Avalanche is built on GM’s new full-size SÚV platform, which incorporates features such as a new, fully boxed frame, coil-over-shock front suspension, rack-and-pinion §teering and an all-new, premium interior system that bolster the vehicle’s comfort, quality and capability. Wider front and rear tracks enhance handling and vehicle stability for a more confident road feel.
Extensive attention to detail was paid by Avalanche’s engineers to ensure a quiet driving experience. The new, stiffer frame reduces vibrations transmitted to the passenger cabin, while the strength and accuracy of the fully boxed frame also enable more precise mounting and tuning of chassis and suspension components. This helps reduce vibration – even the tires on the large, 17-inch and 20-inch wheels were designed to reduce noise.
Noise-reducing components and materials are used throughout the body structure, including the headliner material, door seals and front-of-dash area. The engines also feature a quiet-tuned alternator and an acoustically tuned engine cover that reduces engine noise heard inside the vehicle. New door seals help reduce seal ‘pull-away’ at highway speeds, which can cause wind noise.
Avalanche’s quietness and smoothness are complemented by the Autoride suspension system, which is standard on LTZ. This §egmènt-exclusive bi-state, real-time damping system provides an extremely refined ride with greatly reduced body motion. The system consists of a semi-active, two-position damping control system that responds in real time to road and driving conditions, based on body and wheel motion sensors.
Avalanche offers up to 8,000 pounds (3,629 kg) of towing capability, when properly equipped, enhancing its flexible, ready-for-anything capability.
Safety story
The ’07 Avalanche offers security in the form of a 360-degree safety system of occupant protection and crash-avoidance technologies. New features include roof-mounted head curtain side air bags with rollover protection for both rows and front-seat safety belt pretensioners that are linked to the vehicle’s sensing system to provide §egmènt-exclusive deployment in rear-end crashes.
These features are integrated into a stronger vehicle structure that is also designed for improved compatibility with other vehicles. The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment. Sensors located at the front of the vehicle, in the side doors, and within the occupant compartment provide increased and more immediate crash detection. The vehicle’s sensing system provides industry-exclusive capability to deploy front seat safety belt pretensioners during certain rear-end collisions, enhancing the belt system’s ability to hold the occupants firmly in place.
The roof-mounted head curtain side air bag system incorporates one of the §egmènt’s first rollover indication sensors, which is located on the vehicle’s center tunnel in the occupant compartment. The sensor monitors the vehicle’s accelerations and roll rate. If these signals indicate an impending rollover, the roof-mounted head curtain side air bags deploy to provide an extra measure of occupant protection and containment. These rollover-capable head curtain side air bags stay inflated longer than air bags developed only for side impacts because rollover incidents can last longer. The deployment duration and other design features of the rollover-capable air bags combine to provide increased occupant protection and the ability to help keep occupants inside the vehicle.
Crash avoidance is bolstered through enhanced design and driver control dynamics, such as wider front and rear tracks, as well as more responsive suspensions – including a new coil-over-shock front suspension design and new rack-and-pinion §teering. The vehicles are built on a stronger and stiffer, fully-boxed frame that contributes to enhanced crash energy management. The front frame section has been designed to optimize crush progression, resulting in improved energy absorption efficiency. The improved crush performance, enabled by hydroformed frame rails and efficient chassis component packaging, also comprehends design provisions that help improve vehicle-to-vehicle compatibility in the event of a frontal impact with a smaller vehicle.
Additional safety features include:
Standard StabiliTrak stability control system with rollover mitigation technology
Standard dual-stage driver’s front air bag
Standard dual-stage outboard-front passenger air bag with Passenger
Sensing System
Available roof-mounted head curtain side air bags for both seating rows

Available rearview camera system designed to provide the driver with
a view of people or objects in the rearward path of the vehicle
Standard pull-up/push-down power window switches
All models come with the Generation 6 OnStar system (with a one-year Safe and Sound service plan). The system includes the General Motors Advanced Automatic Crash Notification (AACN) system, making crash data available to emergency services to potentially dispatch the appropriate life-saving personnel and equipment to crash scenes faster. If the vehicle is in a crash that activates an air bag, the OnStar system automatically notifies an OnStar advisor, who will check on the occupants or summon emergency help if necessary. OnStar also can assist authorities in locating a vehicle if it is reported stolen (ability to locate stolen vehicles varies with conditions).
