Buses have been used as one of the main and important public transportation facilities in society. Especially for high-speed coaches, they have been played and will play an important role in a long-distance transportation system between city-to-city and state-to-state in future. In general, the size of engine installed in a high-speed express coach is on the range of 12~16 liters in displacement volume and 800~1,200 kw in brake power. Its fuel consumption is surprisingly high and the rate is on 2.5~3.5 km/liter in its cruising speed(110km/h) on a high speed. In this research, a streamlined design of a high-speed, long-distance coach was studied to understand its effect on the fuel consumption and carbon dioxide reduction compared to its original configuration. For this, one of popular models of high-speed express bus was selected and compared its aerodynamic performance to its streamline designed model"s. For a streamlined design of the model bus, a frontal configuration of the vehicle was modified to reduce the stagnation pressure drag and an IDRD (induced drag reduction device) was installed to reduce the induced drag at the rear-side of the bus. Five models of streamlined designed vehicle were developed with the combination of the modified frontal area and rear spoiler. From the study, it was found that 27.4% of the total drag of the original bus (Model-0) was reduced on the model-3 that is equivalent to 17.3kW of an engine brake power at 120km/h in speed. The annual economical effect is the reductions in about 14,610 liters of fuel and 41.2 tons of CO2 per year by each car at the assumed operating condition.
