Hi All,
Look over the driver on the new Matrix. The roof peaks, and then is downhill towards the aft. So, the thirdman model is incorrect, and not predictive.
The downhill section is going to impart downward movement to the air. If they did not have that extension, flow would seperate in front of the rear of the car a little bit. That the extension is for, to keep the flow from sepearting.
The tip of the spoiler is higher than the lowest portion of the roof. But well below the height of the roof over the driver.
