Abstract

An adjustable aerodynamic system for a motor vehicle includes a deployable rear spoiler assembly, a deployable rocker extension assembly and a deployable air dam assembly. The deployable rear spoiler assembly includes a main body portion operatively associated with the rear deck lid and linearly translatable rearward to a deployed position. The deployable rocker extension assembly includes a lower member and an intermediate member. The lower member is driven by a ball screw motor to a deployed position and the intermediate member is downwardly spring biased so as conceal a gap created between the vehicle and the lower member upon deployment. The air dam assembly is operatively associated with the front facie and downwardly translatable to its deployed position. In the deployed position, the air dam functions to lower the front profile of the vehicle and further functions to block one or more venting passages in the front facia.
