What is the ground clearance of the Audi A7 with adaptive air suspension?
The ground clearance of the Audi A7 with adaptive air suspension varies depending on the drive mode selected. In Dynamic mode, the clearance is approximately 120 mm (4.7 inches), while in Comfort or Auto mode, it increases to around 135 mm (5.3 inches). In Lift mode, the clearance can reach up to 145 mm (5.7 inches) for improved off-road capability.
Q3 How does the adaptive air suspension system work?
How does the adaptive air suspension system work?
The adaptive air suspension system in the Audi A7 uses air springs and electronically controlled dampers to adjust ride height and stiffness based on driving conditions. Sensors monitor vehicle speed, road surface, and driver inputs to automatically adjust the suspension settings. The system also allows manual adjustment through the Audi Drive Select system, offering modes such as Comfort, Dynamic, and Lift.
Q4 What is the recommended tire pressure for the Audi A7 to maintain optimal suspension performance?
What is the recommended tire pressure for the Audi A7 to maintain optimal suspension performance?
The recommended tire pressure for the Audi A7 varies depending on the tire size and load conditions. For standard 19-inch tires, the front tires should be inflated to 36 psi (2.5 bar) and the rear tires to 39 psi (2.7 bar) under normal load conditions. For full load conditions, increase the front tire pressure to 39 psi (2.7 bar) and the rear to 42 psi (2.9 bar). Always refer to the tire pressure label on the driver's door jamb for specific recommendations.
Q5 Can the suspension system be upgraded or modified for better performance?
Can the suspension system be upgraded or modified for better performance?
Yes, the suspension system of the Audi A7 can be upgraded or modified. Aftermarket options include performance coilovers, lowering springs, and upgraded sway bars.
