The major target of automotive industries in the production of vehicles is achieving vehicle fuel consumption. The resources of fossil fuels getting depleted and the prices are increasing. Sino truck is one of the successful vehicles being used in the transportation of goods. There is a need to develop fuel-efficient Sino truck. There are many fuel-saving technologies are tried by researchers and engineers. Out of which designing of the aerodynamic shape of a vehicle for reduction of drag is observed to an important method for fuel be saving. An effort is made for reducing the aerodynamic drag of Sino truck model-321 by modifying the tractor-trailer gap with an aerodynamic shape. The modified Sino truck with different tractor-trailer gap shapes is analyzed using CFD to find their influence on the flow around Sino truck. Also, the analysis was done to identify the critical zones where the drag is more. CFD analysis was done on modified Sino truck by varying trailer and tractor gap, varying the height of the trailer concerning cab, varying the shape of the roof of the trailer and with under trailer coverage. The analysis was done at different speeds from 64 to 96 kmph with 12 m/s crosswinds. Out of all these, it is observed that undercarriage coverage has a great influence in the reduction of drag resistance. Modifications on the rear side of the trailer helped in reducing the separation of the flow separation and in the reduction of drag.
