It's a feature designed to improve aerodynamics - it is intentional - the bumper leads slightly with one side to get the air flowing to the side instead of confronting the wind with a straight bumper wall. It's subtle but effective. Engineering genius.
Doors and panels are designed to slightly “shingle” too, front to back.It's a feature designed to improve aerodynamics - it is intentional - the bumper leads slightly with one side to get the air flowing to the side instead of confronting the wind with a straight bumper wall. Same for slight bumper height differences side to side, wheel cover alignment differences - every little nuance of uneven surface or apparent assembly anomaly introduces a vortex effect that increases range or reduces wind resistance. It's subtle but effective. Engineering genius.
