In India coach buses are generally used for long journey from 400 km to 600 km. Volvo B11R bus is widely used by private as well as state government players for its comfortable ride and luxurious feel. No engine is 100% economical so few other parameters influence the fuel consumption and one of them is Aerodynamic drag which depends on exterior body. Without affecting structural integrity of bus body B11R the design changes done with conforming Bus body code AIS-52.CATIA V5 R19 is used for bus body model and Ansys fluent for CFD analysis. Existing bus body CFD analysis is compared with modified design of bus body on different speed varies from 80 kmph to 120 kmph cause the aerodynamic effect is prone on these speed ranges. Drag coefficient is compared both models and analyzed for future design of bus body. Keywords: Economical, Aerodynamic drag, AIS 52, Catia V5 R19, Ansys fluent
