Abstract
The disclosure provides a vehicle body lower structure, which can improve aerodynamic performance and improve driving stability. The vehicle body lower structure includes an airflow guiding plate that is arranged on the vehicle body of a vehicle and is movable between a receiving position covering the lower part of the vehicle body and a deploying position protruding downward. The airflow guiding plate includes a first airflow guiding plate and a second airflow guiding plate. The first airflow guiding plate is arranged in front of the left and right front wheels of the vehicle, and the second airflow guiding plate is arranged under the center of the vehicle body. Moreover, the protruding amount of the first airflow guiding plate is different from the protruding amount of the second airflow guiding plate in the deploying position.
