Introduction
Active Cornering Enhancement (ACE) is an advanced suspension technology designed to dramatically improve vehicle stability during cornering maneuvers. Originally pioneered by Land Rover for the Discovery Series II, this innovative system reduces body roll and keeps vehicles level through tight turns, offering drivers enhanced control and confidence on both roads and off-road terrain.
What Is Active Cornering Enhancement?
ACE is a computer-controlled hydraulic anti-roll system that actively combats body roll in real-time. Discovery Series II is the only production sport-utility vehicle that features Active Cornering Enhancement (ACE), an optional system that reduces vehicle body lean during cornering.
The system uses two accelerometers positioned front and rear to detect lateral acceleration and body lean immediately when steering input is applied. By constantly adjusting the suspension ride height to maintain a level ride, Active Cornering Enhancement (ACE) improves handling, decreases body roll, boosts stability, and improves comfort while driving.
How ACE Works
The ACE system operates through an elegant three-part process:
- Sensor Detection: Accelerometers monitor lateral forces acting on the vehicle during cornering
- Electronic Processing: The ACE ECU processes data from sensors, vehicle speed, and steering angle in milliseconds
- Hydraulic Response: Pressurized hydraulic fluid from the ACE pump flows to actuators that stiffen one side of the suspension while relaxing the other
ACE can counteract up to 1.0 g of lateral acceleration in less than 130 milliseconds, helping to make Discovery Series II feel more stable and responsive during corner.
Key Benefits of ACE Technology
Enhanced Stability: ACE reduces body roll, reducing the amount of lost contact between tyres and the road, enhancing traction and vehicle stability.
Improved Safety: According to Consumer Reports’ automotive technology research, advanced suspension systems like ACE reduce rollover risk by up to 50% in SUVs and significantly improve passenger comfort and vehicle control.
Better Handling: The system virtually eliminates lateral body movement, allowing for sharper cornering and more responsive steering feedback without driver input.
Increased Comfort: Reduced body roll produces smoother, more comfortable trips, especially on tight turns and winding roads.
Maintenance and Costs
Regular maintenance is essential for ACE system longevity. Key maintenance points include:
- Fluid Checks: ACE requires high-quality hydraulic fluid; check levels during regular 12-month service intervals
- Component Replacement: ACE pump or valve block replacement typically costs $150-$500 or more
- Preventive Care: Routine checks prevent costly repairs and maintain system effectiveness
If your vehicle performance drops, it may not just be ACE—it could also be your engine or transmission. In such cases, choosing a low-mileage used engine or a tested used transmission can restore performance without high costs.
Future of Active Cornering Enhancement
The future promises even more sophisticated systems with the integration of AI and machine learning, ensuring that the vehicle not only reacts to current conditions but anticipates them. Electric vehicles will benefit from integrated ACE systems optimized for regenerative braking and energy efficiency.
Conclusion
Active Cornering Enhancement represents a significant advancement in automotive suspension technology, combining superior safety, handling, and comfort. Whether you’re navigating mountain switchbacks or cruising highways, ACE works silently to keep your vehicle stable and composed.
According to Consumer Reports, advanced vehicle safety technologies significantly improve stability and reduce accident risks.
Frequently Asked Question
What is Active Cornering Enhancement (ACE)?
Active Cornering Enhancement (ACE) is an advanced suspension technology designed to improve vehicle stability and handling during turns. It uses hydraulic actuators and sensors to reduce body roll when cornering, ensuring better tire contact with the road and enhanced driving control.
How does Active Cornering Enhancement work?
ACE works by automatically adjusting the suspension stiffness in real time. Sensors detect steering input, speed, and lateral forces, and the system applies counteracting force through hydraulic mechanisms to keep the vehicle level during sharp turns.
Which vehicles use Active Cornering Enhancement?
ACE is commonly found in premium SUVs and off-road vehicles, especially models from Land Rover. It is featured in vehicles like the Range Rover and Discovery for improved on-road comfort and off-road capability.
What are the benefits of ACE?
The main benefits of ACE include reduced body roll, improved handling, enhanced passenger comfort, and increased safety. It allows drivers to maintain better control during high-speed cornering and uneven terrain conditions.
Can ACE be repaired or replaced?
Yes, ACE systems can be repaired or replaced, but they require specialized knowledge due to their hydraulic and electronic components. Regular maintenance is important, and replacement parts can be sourced from authorized dealers or trusted auto parts suppliers.
