Drag reduction spoiler

A vehicle comprising:

• a roof panel and a rear windshield disposed downward from the roof panel;
• a drag reduction spoiler configured for attachment to the vehicle, the drag reduction spoiler comprising:
• a fixed spoiler portion configured for attachment to the roof panel;
• an extendable top portion configured for movement relative to the fixed portion, the extendable top portion including a first top portion and a second top portion;
• first and second side spoiler portions configured for attachment to opposing sides of the rear windshield;
• and
• at least one actuator configured to deploy the extendable top portion, the at least one actuator being secured to the first top portion;
• wherein the first and second side spoiler portions have a stowed position and a deployed position;
• wherein the extendable top portion has a stowed position and a deployed position;
• wherein the first and second side spoiler portions are configured to pivot about a hinge axis between a folded configuration defining the stowed position and a generally vertical configuration defining the deployed position, the stowed position being generally horizontal adjacent the rear windshield and the deployed position being generally vertical relative to the rear windshield;
• wherein the first and second side spoiler portions each include a first end having a first radius of curvature and a second end having a second radius of curvature, the second radius of curvature being greater than the first radius of curvature.

A method of deploying a drag reduction spoiler for a vehicle comprising:

• providing a spoiler having a fixed portion configured for attachment to the vehicle, an extendable top portion configured for movement relative to the fixed portion, the extendable top portion including a first top portion and a second top portion, and first and second opposing side spoiler portions configured for movement relative to the vehicle;
• providing at least one actuator configured to extend and retract the extendable top portion, and securing the at least one actuator to the first top portion;
• providing a side actuator for each of the first and second opposing side spoiler portions;
• actuating the side actuator for each of the first and second opposing side spoiler portions and pivoting the first and second opposing side portions from a folded stowed configuration to an upright deployed configuration;
• and
• actuating the at least one actuator and extending the first top portion to an extended deployed position, the first top portion engaging the second top portion and pulling the second top portion to an extended deployed position.
