Chevrolet Avalanche's quietness and smoothness are complemented by the Autoride suspension system, which is standard on LTZ. This segment-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.

Chevrolet 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 Chevrolet 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 segment-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 segment'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 steering. 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.
