What type of suspension system does the 2012-2018 Audi S7 use?

The 2012-2018 Audi S7 is equipped with an adaptive air suspension system, which includes air springs and electronically controlled dampers. This system allows for adjustable ride height and damping characteristics, providing a balance between comfort and sporty handling.

What is the ride height adjustment range of the Audi S7's air suspension?

The adaptive air suspension on the Audi S7 offers a ride height adjustment range of approximately 25 mm (1 inch) in both directions. The system can lower the vehicle at high speeds for improved aerodynamics and raise it for better ground clearance on rough terrain.

How does the Audi S7's suspension handle dynamic driving conditions?

The Audi S7's suspension system features dynamic ride control (DRC) and Audi Drive Select, which allows the driver to choose between multiple driving modes (Comfort, Auto, Dynamic, and Individual). These modes adjust the damping force, throttle response, and steering effort to optimize handling and stability during dynamic driving conditions.

What is the recommended maintenance schedule for the Audi S7's suspension components?

Audi recommends inspecting the suspension system, including air springs, dampers, and bushings, every 20,000 miles or 2 years, whichever comes first. Regular checks for leaks, wear, and proper alignment are essential to maintain optimal performance and safety.

Can the Audi S7's suspension be retrofitted with aftermarket components?

While aftermarket suspension components are available, Audi strongly recommends using genuine OEM parts to ensure compatibility, performance, and warranty compliance. Non-genuine parts may affect the vehicle's handling, safety, and warranty coverage.
