Audi Q7 4M air suspension front dust cover product introduction

1. Excellent comfort
   The intelligent air pressure adjustment system can adjust the spring stiffness in real time according to the road conditions (response time >50ms), reduce the body vibration by 60%, and greatly improve the driving comfort. Test data shows that when driving on rough roads, the noise inside the car is reduced by 5-8 decibels.

2.  

   Precise body control

• Automatic leveling function (error ±3mm) ensures stable body posture under any load conditions

• Automatically lowers body height (20-40mm) to reduce wind resistance when driving at high speed

• Automatically strengthens outer support force in curves (maximum increase of 30%)

3. Enhanced passability
   In off-road mode, the chassis height can be increased by 45-80mm, and the four-wheel drive system can increase the pass angle by 5-8°. The specially designed anti-scratch airbag has a service life of more than 100,000 times under complex road conditions.

4.  

   Smart interconnection function
   The ECU control system supports OTA upgrades and can memorize and store 5 driving mode parameters. Real-time monitoring of air pressure (accuracy ±0.1Bar) and system health status through the mobile phone APP.

3. Excellent durability
   The multi-layer composite airbag has passed 2 million fatigue tests (far exceeding the industry standard of 1 million times). The core components are made of aviation-grade aluminum alloy with a corrosion resistance level of C5.

3. Energy saving and environmental protection
   Compared with traditional steel suspension, it can reduce weight by 30-50kg and reduce fuel consumption by 3-5% under comprehensive working conditions. The closed-loop gas circulation system achieves zero pollution emissions.
