Definition of Front End Opening is main development factor to develop vehicle exterior design and vehicle performance for Aerodynamics and powertrain cooling. This front opening definition has to be applied in early design development stage. And required opening area based on vehicle performance condition should be reflected to this definition. This opening is key factor for styling and engineering design to meet styling needs and performance requirement. In terms of vehicle performance, this opening is area to supply cooling airflow (FEAF, front end airflow) for powertrain and a factor to generate drag in engine room compartment. This study is to develop a method to optimize front end opening and to develop a prediction tool and supply a tool to design studio to meet each requirement by Kriging method that is one of DFSS tools.
