Avancier ADS refers to the Adaptive Damper System, which is a type of adjustable shock absorber. This is a relatively advanced technology installed in vehicles. During driving, the system can adjust the damping force based on the driver's habits and road conditions, allowing the driver to modify the shock absorber's stiffness to maximize ride comfort. The Avancier is a mid-size SUV produced by Honda. The Honda Avancier is equipped with an engine coded 15BD, which has a maximum power output of 142 kW, a maximum torque of 243 Nm, a maximum power speed of 5,600 rpm, and a maximum torque speed ranging from 2,000 to 5,000 rpm.

While studying Honda's technical documentation, I discovered that the ADS in the Avancier stands for Adaptive Damper System. This system monitors road conditions 500 times per second via body sensors and automatically adjusts the damper's damping force. Once, when driving a friend's Avancier on a gravel road, I could clearly feel the chassis filtering out all the minor bumps. When the system detects sharp turns or sudden braking, the suspension immediately stiffens to maintain body stability. In Sport mode, the damping is stronger, reducing cornering body roll by nearly 40%; in Comfort mode, going over speed bumps feels like driving over a piece of cotton. The most unique feature is its proactive prediction function—when encountering continuous potholes, it adjusts the damping in advance, making it far more intelligent than ordinary suspensions.

When our car club discussed the Crown configuration, we specifically researched the ADS, which is essentially Honda's cutting-edge suspension system. It features additional electronic control valves compared to conventional suspensions, allowing it to anticipate road conditions based on GPS data. For instance, frequent highway drivers will notice that the suspension automatically stiffens when entering or exiting tunnels or crossing bridge joints to reduce body sway. This system also has a hidden function: when detecting consecutive S-curves, it automatically locks the damping, making cornering as stable as a rail car. Crown owners generally report that ADS is more durable than air suspensions, as there's no concern about airbag aging or leaks, resulting in significantly lower costs.

Last time when accompanying my relative to pick up the Avancier, the manager gave a detailed introduction to the ADS system. Simply put, it's an intelligent suspension that can automatically adjust its stiffness: the shock absorbers act like sponges to absorb vibrations on rough roads, then transform into sturdy pillars when cornering. During the test drive, I specifically compared the ADS system's on and off states – the difference was particularly noticeable when going over speed bumps. With ADS on, there was only a dull 'thud' sound inside the cabin, while turning it off resulted in a metallic 'clang' sensation. The system can also memorize frequently traveled routes; for example, after passing the speed bumps at the residential area entrance daily, the suspension would automatically soften in advance starting from the third day. Elderly family members said they experienced much less motion sickness riding in this car.

As a commuter who drives 80 kilometers daily, the Crown Road ADS is my most relied-upon feature. During morning rush hour traffic jams, it smoothens the frequent start-stop pitching sensation; on highways when encountering road joints, the suspension instantly stiffens to prevent body bounce. The system predicts turning actions through the steering wheel angle sensor—once during rainy highway obstacle avoidance, I distinctly felt the outer shock absorber supporting the vehicle body. The most practical feature is the loading mode: when the trunk is packed with camping gear, holding the ADS button for 3 seconds automatically raises the rear suspension to prevent chassis scraping. This system reacts faster than BMW's air suspension yet requires much simpler , with no failures in six years.

The Avancier ADS essentially replaces modified suspensions with algorithms. Conventional modifications tend to be either too stiff or too soft, while it achieves both characteristics simultaneously: soft as a boat when passing over cement road joints, yet stable as a performance car during emergency lane changes. The sensors collect data including vehicle speed, steering angle, braking force, and even the status of the air conditioning compressor. Once, when fully loaded with the air conditioning on while climbing a slope, the system automatically reinforced the rear axle support. The most interesting aspect is its ability to learn driving styles—after three days of aggressive driving, the system's damping baseline automatically increases. Owners are advised to watch for the green indicator light flashing on the dashboard when the ADS is active, especially when going over speed bumps.
