Mod Description
The venturi effect is the action of negative pressure behind an object as air passes over it. In this case, the negative pressure pulls all the dirt into the back of the car making it dirty far more quickly than any other part.Mod Details

The picture above shows the air pressure on the smart as it travels forwards. This thin layer of compressed high pressure air diverts a lot of the dirt and bugs over the car keeping it averagely clean.
As the smart moves forwards it pushes the air around the body. An area of low pressure is created behind the car. Low pressure will pull air from the surroundings to fill the gap drastically altering the air flow around the rear.
The change in direction of the air creates ‘eddies’ which pull the dirt off the road, soot from the exhaust and passing bugs into the rear of the car. This can be worsened if you have a non standard exhaust as the emissions get caught in the low pressure eddies as opposed to being dispersed by the airflow from under the car.
