Abstract
In the development of a transportation technology, efforts have been made to increase vehicle efficiency by optimizing
aerodynamic aspects. In the automotive field, aerodynamics has a huge role in determining vehicle body design. This research
was carried out by simulating and analyzing the Obhi-Mec Unud bio-hybrid vehicle body model using ANSYS Fluent to see
the effect of vehicle body modifications on the drag coefficient, lift coefficient, and the shape of the air flow pattern on the
surface of this vehicle body. The design before modification provides a smaller drag coefficient value, while the design after
modification provides a smaller lift coefficient value. Increasing vehicle speed will increase the drag coefficient value.
However, increasing vehicle speed will produce different airflow patterns in each body design.
