The height from an end of a front bumper to a front wheel center is within a predetermined value.

Abstract: Disclosed herein is a variable rear spoiler apparatus of a rear bumper for a vehicle. The variable rear spoiler apparatus includes a linkage mechanism configured to be installed on a bumper back beam and having a length varying in a vertical direction when the linkage mechanism undergoes a rotation.

Abstract: An adjustable rear bumper spoiler system for a vehicle controls air turbulence by driving the air spoiler device so that the vehicle can be pressed downwards during high-speed driving. The adjustable rear bumper spoiler system also controls air turbulence by driving flap devices so that the vehicle body is pressed downwards with respect to the turning direction during turning. This consequently improves the driving performance and driving reliability of the vehicle.
