any thoughts on fender vents for the wheel wells? bmw uses them on the front
and mercedes is even using them in the rear for their super low drag EQS
also hyundai uses something called '' ''separation traps on both sides of the rear bumper '' for their new ioniq 6 which is also low drag, but they never specifiy exactly what they are or how they work.
