Abstract

Automotive systems and methods for operating vehicles are provided. In an embodiment, when a speed sensor senses that the vehicle speed is above a first speed threshold and an ambient light sensor senses that an ambient light intensity is below a first intensity threshold, a controller provides a first command to a suspension system to lower a first end of a vehicle body to a second front trim height position relative to a horizontal plane, where the second front trim height position is below a first front trim height position, and to lower the second end of the body to a second rear trim height position relative to the horizontal plane, where the second rear trim height position is below a first rear trim height position.
