ABSTRACT:
Normally all the car bodies are streamlined for very less wind drag coefficient, but still due to the length of car
as constraint the rear portion of the car was not fully streamlined. The present paper objective is to design the
wind friction reduction attachments to the rear portion of a car which can be opened and closed depending on the requirement, thereby mileage of the vehicle at high speeds will be improved and the car can travel at higher speeds without increasing the engine capacity. The rear attachments of car can be closed in traffic and parking
periods and when the vehicle is travelling on highways at high speed, the attachments are opened. To open and
close the wind friction reduction attachments a hydraulic system is designed. The wind friction reduction attachments are designed to be inside the rear door in the closed condition so that there won’t be any problem in
aesthetic point of view.
