Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension system does the 2022-present Acura MDX use?

The 2022-present Acura MDX features an advanced Adaptive Damper System with Amplitude Reactive Dampers. This system adjusts damping force in real-time based on road conditions and driving dynamics, providing a balance of comfort and performance. The front suspension is a MacPherson strut design, while the rear uses a multi-link setup.

What is the ground clearance of the 2022 Acura MDX?

The 2022 Acura MDX has a ground clearance of 7.3 inches (185 mm) for standard trims. For the MDX with the Advance Package, the ground clearance remains the same, but the adaptive suspension system enhances off-road capability and stability.

How does the Integrated Dynamics System (IDS) affect the suspension?

The Integrated Dynamics System (IDS) in the 2022 Acura MDX allows drivers to select between Comfort, Normal, Sport, and Snow driving modes. Each mode adjusts the suspension damping, steering response, and throttle mapping. In Sport mode, the suspension becomes firmer for improved handling and cornering stability.

What is the recommended tire pressure for optimal suspension performance?

The recommended tire pressure for the 2022 Acura MDX is 35 psi (241 kPa) for all four tires. Maintaining this pressure ensures proper suspension performance, ride comfort, and tire longevity. Always check tire pressure when the tires are cold for accurate readings.

Can the suspension be adjusted manually?

No, the suspension on the 2022 Acura MDX is not manually adjustable. The Adaptive Damper System automatically adjusts damping force based on road conditions and driving dynamics. However, the Integrated Dynamics System (IDS) allows drivers to influence suspension behavior by selecting different driving modes.

What is the towing capacity of the 2022 Acura MDX, and how does it affect the suspension?

The 2022 Acura MDX has a maximum towing capacity of 5,000 lbs (2,268 kg) when properly equipped. The suspension is designed to handle this load, but it is recommended to use a weight-distributing hitch for heavier loads to maintain stability and prevent excessive strain on the suspension components.
