    Hello fellow Xers,

    We've recently added a 2016 Model X to our fleet.
    I don't like the looks of the rigid spoiler and am considering removal.

    Can anyone tell me the benefits - real and imagined - of the spoilers?

    I find it just occludes the already poor rear visibility.

    Thanks
    MDR

    IMO, spoilers, for the most part, are properly named. They spoil the look of the car.

    From a practical point, at high speeds, they increase the downforce on the rear wheels. This is a good thing if you have to make a high speed maneuver. It can help keep the rear of the vehicle at the rear.

    True enough.
    In this case, I've seen where Tesla implies that the spoiler contributes to the low Cd of the Model X
    Just wondering how significant that contribution is.

    The Tesla spoiler is not a downforce spoiler. As noted above it’s there to reduce drag and clean up / direct the airflow coming off the rear.

    It’s only effective at highway speeds. I would guess it improves range 2-5% at speeds over 55mph.
