Nice oneOriginally posted by ditzy:No windows = no problems at all.![]()
no windows mean more air will come in? wun it screw up the aerodynamics even more??Originally posted by ditzy:No windows = no problems at all.![]()
A boeing 747 has so many windows, but no one's complaining right?Originally posted by Icemoon:no windows mean more air will come in? wun it screw up the aerodynamics even more??

That proves windows closed better lor. You cannot say boeing 747 inside no aircon also.Originally posted by Icemoon:talk cock.
none of the windows open mah.

But they can leave their doors open. Do you drive around with your doors open? I don't think so.Originally posted by Icemoon:talk c-o-c-k.
not as if 747 has the option of leaving windows open when flying.![]()
Above 80km/h windows down acts as a drag. If you're in crusing speed you're already saving fuel so having the air-con on will have not much of an effect.Originally posted by Icemoon:I read a magazine article saying the window should be down, to reduce the aerodynamic side-effects. Having the window up is like an open parachute, slowing down the car.
The whole issue is about saving fuel.
But I thought having windows down means switching on air-con which eats up fuel as well?!
So how?
opps .. I didn't know having windows down will slow down the car on the expressway.Originally posted by nullifi3d:Above 80km/h windows down acts as a drag. If you're in crusing speed you're already saving fuel so having the air-con on will have not much of an effect.
You're theory is the opposite. Windows up is more aerodynamic than windows down.

I will close window on expressway from now on ..Originally posted by mr sunray:Think < 80km/h won't slow your car down but > 80km/h will.
So open windows < 80km/h = no problem.
But open windows > 80km/h = big problem.
So which problem you want??
It's not a matter of the car slowing down per se. For every car design there is a certain amount of drag. In this cas the matter of having the windows down above 80km/h will create a little more drag but not substantial enough to cause the car to slow down.Originally posted by mr sunray:Think < 80km/h won't slow your car down but > 80km/h will.

i think you've mixed up "up" & "down", unless your windows so special, close by winding down.Originally posted by Icemoon:I read a magazine article saying the window should be down, to reduce the aerodynamic side-effects. Having the window up is like an open parachute, slowing down the car.

Wow, if this is true, we can save fuel two ways. Wind down the window and last longer distance and you switch off the aircon which also save the fuel.Originally posted by Kuali Baba:Mythbusters took 2 identical cars to a race track and brimmed them with fuel for an endurance race. One car had the windows wound down (with the air-con off) and it lasted a few laps longer than the one which was sealed but had the air-con running.
