I put this on GTV6.com, too.

At standard ride height:
Width of an Alfa 75: 1.66 metres.
Height of an Alfa: 1.4 metres.
Frontal area of an Alfa 75: 2.324 square metres.

At 110km/hr you travel 30.56 metres/second.

At 110km/hr, a 75 displaces about 71.02 cubic metres of air every second. That's 71021.44 litres of air per second. 255677184 litres of air displaced in 1 hour @ 110km/hr.

From the ever reliable intrawebz, I found out that air at sea level on a 25*C day weighs 1.18Kg/cubic metre.

So at 110km/hr, a 75 moves 83.804Kg of air out of the way every second. Or 301692.96Kg of air every hour........

Travel for 4 hours at 110km/hr and you shovel over 1.2million Kg of air out of the way in a standard height 75  :o

I want to know which smartass came up with the idea of weighing air?

whilst i dont know, it comes in really handy when designing commercial/industrial AC, but possibly not much else  :)
