No, this is not correct. The volumetric flowrate of the air captured by the inlet generally increases somewhat with vehicle speed. Volumetric flowrate = velocity * area. Think about how much flow area it takes to recieve 1 cubic meter per second of cooling air at a vehicle speed of 10 m/s as compared to a speed of 1 m/s.
