Abstract: Disclosed is a vehicular roof rack that is adapted for reducing wind noise. It includes left and right pedestals for attachment to the vehicle and extending above a roof of the vehicle. It further includes an elongated crossbar extending between the left and right pedestals and above the roof of the vehicle, the crossbar having a leading edge, a trailing edge, and a profile along substantially all of its length, the profile including a smoothly curved envelope with no outwardly protruding portions extending outside of the smoothly curved envelope and with at least one step-down groove that is inside of the smoothly curved envelope and located nearer to the leading edge of the crossbar than to the trailing edge. The step-down groove may be on the top, the bottom, or both sides of the crossbar. The pedestals may include step-down grooves that substantially align with the step-down groove of the crossbar.
