A wind turbine rotor blade with an airfoil having a suction side and a pressure side is provided. The airfoil comprises an inner airfoil portion and an outer airfoil portion, where the inner airfoil portion is comparatively thicker than the outer airfoil portion and provided with vortex generators. The thickness of the inner airfoil portion is between 30% and 80% of the inner airfoil portion's chord length, and the vortex generators are located at the suction side of the inner airfoil portion between 8% and 12% of the chord length, as measured from the leading edge of the airfoil portion.
