Thanks to targeted aerodynamic measures such as air vent control the active rear spoiler or the air curtain in the front apron your bmw is able to achieve an optimised drag coefficient.
Bmw air curtain system.
This has a positive effect on efficiency and driving stability while also reducing the noise level in the cabin.
The 4 series has so called air curtains and air breathers similar to those on the new bmw x5.
Many factors enter into considering installing an air curtain such as local environment what is going through the door.
Good ideas don t always have to be complicated.
