As the first pure electric sedan of BYD TOYOTA EV Technology Co.,Ltd,the bZ3 has extremely high energy consumption requirements,which brings great challenges to its aerodynamic development.To achieve this target,CFD simulations and wind tunnel tests were conducted by the aerodynamics team.Optimizations were primarily focused on areas including styling,undercover design,cooling air inlet management,wheels and sealing.The final production car was tested in the wind tunnel,achieving a drag coefficient of 0.218,which is at a leading level among vehicles in its class.Different CFD methods were compared with test results,showing that the LBM has better accuracy,although its precision in simulating underbody airflow still needs to be improved.
