Wing Blocker?

[78F350]

Boxsters do not have a "wing". It is a spoiler. It provides down-force when it raises (automatically at about 75 mph), with less drag than a wing.

According to the owner's manual: "The rear spoiler reduces air resistance and, particularly at high speeds, reduces rear axle lift."

Some people don't like the way it looks, but it is effective and efficient. Aerodynamically it works much like a Gurney flap, with the rear of the car.

it does not produce down force, it reduces lift
It is basic aerodynamics.

Not to quibble, but I used the term down-force, thinking that it would be more proper on a car forum than the aerodynamic term I would use at work, 'negative lift'.

Negative lift: An aerodynamic downward force created by any airfoil. /or/ The downward component (vector) of lift, relative to the body acted on by the airfoil.

Downforce (from Wikipedia) is a downwards thrust created by the aerodynamic characteristics of a car. The purpose of downforce is to allow a car to travel faster through a corner by increasing the vertical force on the tires, thus creating more grip.

There are other things we can call it too. I don't fault you far saying "it reduces lift", as that is one way to look at its effect on total force.
