With the gradual maturity of intelligent driving technology, driving in platoon is easy to achieve, which might benefit for energy saving. Hence, it is urgent to discover the mechanism of aerodynamic in platoon condition. Aerodynamic drag and mechanism in two-vehicle platooning in different spacing are studied by numerical method with the DrivAer model. As spacing grows, three configuration models share the same law, but the leading and trailing car appear the opposite drag change compared with that in the isolated condition. Pressure changes of some crucial parts and wake field are analyzed in detail. Some new styles of vehicle shape might be needed for driving in platoon.
