The rear sunroof drain pipe of the Audi A4 is located at the very bottom of the door opening, where there are two small holes, each about one centimeter wide and half a centimeter high. Below is a related introduction to the Audi A4: 1. Powertrain: The Audi A4 3.0 comes standard with Audi's patented quattro all-wheel-drive system, providing the vehicle with double the traction. 2. Configuration: The side head-protection airbags cover almost the entire side from the A-pillar to the rear of the cabin; a new intelligent crash sensor designed for the front airbags can detect the severity of an accident, ensuring timely deployment of the airbags. The ESP (Electronic Stability Program) enhances the active safety of the Audi A4 by comprehensively controlling the driving state and assisting the driver in managing the vehicle's behavior in potentially critical situations caused by improper steering.
