Frequently Asked Questions

Find answers to common questions about torque specifications

What type of suspension system does the 2015-Present Audi TTS use?

The 2015-Present Audi TTS features a sport-tuned suspension system with MacPherson struts at the front and a four-link independent suspension at the rear. It also includes Audi Magnetic Ride adaptive damping, which adjusts damping forces in real-time for optimal handling and comfort.

What is the ground clearance of the Audi TTS?

The ground clearance of the 2015-Present Audi TTS is approximately 120 mm (4.7 inches), which is optimized for sporty handling while maintaining sufficient clearance for everyday driving.

Can the suspension be adjusted manually?

The Audi TTS suspension is not manually adjustable. However, the Audi Magnetic Ride system automatically adjusts damping based on driving conditions and can be customized via the Audi Drive Select system, which offers modes like Comfort, Auto, Dynamic, and Individual.

What is the recommended tire pressure for the Audi TTS suspension system?

The recommended tire pressure for the Audi TTS is 39 psi (2.7 bar) for the front tires and 36 psi (2.5 bar) for the rear tires under normal load conditions. Always refer to the tire pressure label on the driver's side door jamb for specific recommendations.

How often should the suspension components be inspected?

Audi recommends inspecting the suspension components every 15,000 miles or 12 months, whichever comes first. This includes checking for wear on struts, shocks, bushings, and control arms, as well as ensuring proper alignment and damping performance.

What is the role of the Audi Magnetic Ride system?

The Audi Magnetic Ride system uses magnetorheological fluid in the dampers, which changes viscosity in response to an electromagnetic field. This allows the system to adjust damping forces within milliseconds, providing a balance between sporty handling and ride comfort.
