A beam blade wiper assembly including a rubber wiping element and an elongated beam having first and second longitudinal ends. The wiper assembly also includes an airfoil having an attachment portion and an upper portion extending between first and second distal ends. The attachment portion includes a flat rib and a pair of legs adapted to operatively engage the rubber wiping element. The upper portion includes a solid base having a leading edge that extends from the base toward the wiping element. The base and the rib define a space that receives the elongated beam. The base and the elongated beam define a cavity that provides flexibility between the upper portion and the attachment portion during wiper operation. The upper portion further includes a spoiler that extends from the base in a manner opposite to the leading edge.
