Many of these buses are available in Ethiopia with a poor aerodynamic shape, which appears to be rectangular blunt, which has a high drag resistance force, leading to increased fuel consumption. Isuzu Midi Bus is one of Ethiopia's most available buses; its external exterior body is locally constructed with a poor aerodynamic shape. In this work, carbon dioxide emissions and fuel consumptions were reduced by aerodynamic improvement of the external body shape of Isuzu midi bus. Analyses were performed numerically using the computational fluid dynamic/ANSYS Fluent modelling of the realizable k-epsilon turbulence. The standard model of the bus modelled on SolidWorks with a scale of 1:20 was investigated at different speeds, and a drag coefficient was observed. It is also tried to reduce the drag coefficient by improving the rear spoiler. Four models have been developed, such as model I, model II, model III and model IV. The drag coefficient was later converted into a quantifiable fuel efficiency performance parameter. The improvement in the aerodynamic configuration of model IV decreased the drag coefficient by 54.35%, leading to a decrease of 32.61% of fuel consumption. This decline in fuel consumption has a major environmental effect.
