I see these pictures today... and I wonder if this has something to do with the turbulent air from the front wing and suspension?
Front View
Simon: Nils? You can close in now. Nils?
John McClane: [on the guard's phone] Attention! Attention! Nils is dead! I repeat, Nils is dead, ----head. So's his pal, and those four guys from the East German All-Stars, your boys at the bank? They're gonna be a little late.
Simon: [on the phone] John... in the back of the truck you're driving, there's $13 billon dollars worth in gold bullion. I wonder would a deal be out of the question?
John McClane: [on the phone] Yeah, I got a deal for you. Come out from that rock you're hiding under, and I'll drive this truck up your ass.
It looks as if it aides airflow to the radiators by helping to clean up the turbulent air from the front aero. It doesn't seem to be able to generate much downforce, if any. I also remember hearing the F1 commentators saying that at certain tracks McMerc runs smaller cooling vents to minimize drag, the result was a fast car that sometimes caught on fire (Monaco '06).
