Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension system does the 2019-Present Audi S8 use?

The 2019-Present Audi S8 is equipped with an adaptive air suspension system with dynamic damping control. This system automatically adjusts ride height and damping force based on driving conditions, offering a balance between comfort and performance. The system also includes Audi Drive Select, allowing drivers to customize suspension settings.

What is the ground clearance range of the Audi S8's air suspension?

The adaptive air suspension system in the Audi S8 provides a ground clearance range of approximately 120mm to 165mm. This range can be adjusted automatically or manually via the MMI system, depending on driving conditions and selected driving mode.

How does the dynamic all-wheel steering system interact with the suspension?

The dynamic all-wheel steering system in the Audi S8 works in conjunction with the adaptive air suspension to enhance stability and agility. At low speeds, the rear wheels turn in the opposite direction of the front wheels, reducing the turning circle. At high speeds, the rear wheels turn in the same direction as the front wheels, improving stability and responsiveness.

What is the recommended tire pressure for the Audi S8 with adaptive air suspension?

The recommended tire pressure for the Audi S8 varies depending on load and driving conditions. For normal driving, the front tires should be inflated to 2.4 bar (35 psi) and the rear tires to 2.2 bar (32 psi). For high-speed driving or heavy loads, adjust the pressure as indicated in the vehicle's owner's manual.

Can the suspension system be manually adjusted for off-road driving?

Yes, the Audi S8's adaptive air suspension can be manually raised to its maximum height of 165mm via the MMI system, providing additional ground clearance for rough or uneven surfaces. However, the S8 is not designed for off-road use, and this feature is intended for mild off-road conditions only.

What is the lifespan of the air suspension components?

The lifespan of the air suspension components, such as air springs and compressors, typically ranges from 80,000 to 120,000 miles, depending on driving conditions and maintenance. Regular inspections and servicing are recommended to ensure optimal performance and longevity.
