Technologies like Active Cornering Enhancement are changing how we manage tight bends as current cars become more sophisticated. By controlling hydraulic pressure and minimizing body roll during tight turns, ACE improves stability.
It gives drivers more confidence behind the wheel by maintaining the vehicle’s balance and control through a network of sensors. The outcome is a safer and more comfortable ride, regardless of whether you are negotiating traffic or curving roads.
This intelligent technology adjusts the suspension in real time according to the driving circumstances. Larger cars benefit most from it as it keeps them level when navigating bends or making abrupt lane changes.
It successfully strikes a mix between comfort and performance and is frequently found in high-end SUVs. We will go over how ACE functions, its importance, and how to keep it up to date for long-term safety in this post.

Appreciating the Technology of Active Cornering Enhancement (ACE)
To optimise vehicle dynamics, Active Cornering Enhancement (ACE), a sophisticated system, automatically regulates body roll while cornering. Increasing steering responsiveness, enhancing cornering stability, and ensuring a smoother ride are its primary goals, especially in SUVs and other vehicles with a high centre of gravity.
Different from ACE, Active Cornering Assist often uses selective braking to help with cornering. With hydraulic actuators and anti-roll bars, on the other hand, ACE physically prevents body roll. As the first luxury SUVs to employ the technology, Land Rover and Range Rover upped the standard for handling and comfort in both off-road and on-road scenarios.
ACE Systems Mechanical Structure and Essential Elements
To enhance vehicle stability during turning, Active Cornering Enhancement (ACE) systems utilise a combination of sophisticated mechanical and electrical components. The main elements and their purposes are explained in depth below, with a clear summary table following.
The control module, which sits at the core of the ACE system, communicates directly with the Electronic Control Unit (ECU) of the car. This module transmits commands to the hydraulic actuators after processing data from many sensors. To resist the lateral forces that induce body roll during turns, the hydraulic actuators located on the anti-roll bars dynamically modify their stiffness.
The responsiveness of the system depends on its sensors. They keep an eye on important aspects like:
- Yaw Stability: The vehicle’s rotating movement around its vertical axis is measured by yaw stability.
- Steering Angle: The steering angle measures the degree and direction of steering input.
- Wheel Speed: Monitors each wheel’s speed to evaluate slip and traction.
The ACE system may modify suspension settings and maintain chassis stiffness based on these sensor inputs, which will keep the car balanced and stable regardless of road conditions and driving style. Comfort and safety are enhanced by the seamless connection with the suspension system, which enables real-time modifications.

The Real-Time Functions of the ACE System
Active Cornering Enhancement (ACE) dynamically modifies suspension behaviour to change how cars react in tight bends. The sensor integration in the system monitors lateral forces that might indicate body roll as you approach a curve. The control module determines the required counterforce instantly, which causes hydraulic actuators to activate the anti-roll bars.
By transferring torque to the outer wheels, this clever intervention improves steering responsiveness and flattens the vehicle’s stance. A notably smoother and more stable ride is the result, particularly when navigating sharp turns or abrupt lane changes. There is a noticeable decrease in roll and improved control for drivers.
Crucially, ACE does not function in isolation. It works in tandem with electronic stability programs to manage braking and avoid oversteer and traction control systems to preserve grip. Together, these systems make sure the car maintains its composure under stress, whether it is negotiating congested city streets or rough back roads.
ACE continually adjusts in real-time when circumstances change during the turn. To maintain traction control and adjust chassis movement, its active body control distributes torque across the wheels. No matter the road surface or driving style, this, when paired with electronic stabilization elements, guarantees the best possible safety and performance.
ACE’s Advantages and Possible Drawbacks
By decreasing body roll and enabling a speedier steering reaction during forceful corners, ACE significantly increases cornering stability. This results in smoother rides on roads and off-road paths and increased passenger comfort. The following are some advantages of Active Cornering Enhancement technology:
Principal Advantages:
- Significantly less body roll and significantly better cornering stability, particularly in big SUVs.

- Check for fluid leaks under the vehicle or near the hydraulic actuator.
- Examine the wires and connections for corrosion or looseness.
- Obtain error codes about ACE components using an OBD-II scanner
Changes in steering response or handling should be carefully monitored, as a delayed response, instability, or unusual feedback might point to underlying system problems. If problems persist, expert diagnostics are recommended. By acting quickly, you can help keep the system operating at its optimal level of efficiency while also avoiding more costly repairs.
Considering the Significance of the ACE Warning Light
Your dashboard’s ACE warning light indicates a possible problem with the system when it glows. A brief light could be a short sensor error, but continuous lighting suggests a more significant issue that has to be fixed.
Reduce your speed and steer clear of abrupt corners until the system verifies whether the light is still on. Consult the owner’s handbook and arrange for a diagnostic check as soon as possible to stop additional damage or impaired vehicle dynamics.
Diagnostic Steps and Repair Considerations
The first step in diagnosing problems with the Active Cornering Enhancement (ACE) system is to use a professional OBD-II or factory diagnostic tool to look for particular error codes. These codes aid in determining if the sensor network, control module, or hydraulic actuators are the source of the issue.
Finding parts and adhering to system-specific troubleshooting protocols requires consulting the owner’s manual (OM) for the vehicle.Preventing significant failures is mostly dependent on routine maintenance. Make sure all ACE-related connectors and fasteners are tight, clean important sensors, and periodically check and replenish hydraulic fluid.
In a variety of driving situations, preventive care guarantees the best traction control reaction and helps maintain cornering stability. pair expenses and extend the system’s lifespan. It is important to seek the advice of trained technicians skilled in suspension tuning and high-end vehicle diagnostics when problems continue or repairs call for component replacement.
