    also not necessarily true... drop a piece of paper, and notice that it prefers to fall flat side down. therefore falling slower than if it is dropped edge side down.

    It's a commercial everything is possible. Lexus just wanted the "wow" factor anyway.

    One thing's for sure - the black Lexus decellerates faster than the grey one

    Pity we didn't get to see its level of fit 'n finish after the landing

    My guess would be "not good".

    Interesting to note that they block the view of the car landing with the car on the ground.

    On a vaguely related note, falling cars, terminal velocities and gravity completely aside, is it me or does the ground-based IS actually look really fast? I appreciate it's got 300 or so ponies, but the launch in particular looked damn quick.

    God damn bulls**t advertising...

    I think the point is that the weight distribution will will affect how the vehicles falls, that is whether it rotates or remains relativity stable.

    As far as, the advert is concerned after seeing it on TV I just assumed it was BS. Giving it more thought would indicate this is probably true.

    If you assume the car falls undercarriage first the entire time, you could assume the car is more or less a flat plate. That being said a flat plate with a Cd of 1.3 weighting 3400lbs has a terminal velocity of approximately 140 MPH. The car has an electronically limited top speed of 142 MPH.

    So the free falling car will have a higher initial acceleration and approximately same top speed. Therefore it will have a larger velocity profile and travel a distance of 4,000 ft faster than the car on the ground.

    Cool Lexus Gravity Ad

    I don't think it was a standing start, though. Still, very cool.

    I always wanted to do the math and make sure Lexus wasn't bullshitting us like most companies do but I never have the patience.
    It has to sustain about 9.8 m/s^2 for 4000 ft., and I personally don't believe it. And if it is true, I'm sure most other competitors can brag their cars 'defy' gravity as well.

    Hmm. 9.8m/sec is a little over 32 ft/sec. So That would mean a 60ft time of about 2 sec. But then it would need to sustain that acceleration or better to beat the falling car to 4000ft. I really don't see a car like that sustaining that kind of acceleration over that much distance.

    Well it depends on if the others have thought to put it that way before..i'm also too lazy to do the math myself but i think it is possible seeing as how there was a rolling start, i just don't think that in the ad it was an actual test run, the final shot when the one on the ground nicks past the falling one, it's way too close for them to risk the life of a driver, I'm sure they calcualted the possibility and it ould theoretically happen but that the final ad is made up of several shots and then the stunt is done with special effects to ensure that the car passes the other safely w/o being hit..makes the most sense

    You guys up top have to take drag into effect.

    You forgot to account for the wind resistance of the falling car, so it wouldn't actually be an average of 9.8m/s^2, rather much less Anyway, Lexus IS350s can accelerate to 100km/h in less 0.2 secs if the acceleration of my 250 is anything to go by. Lexus IS FTW

    Edit: Damn you Rockefella for beating me to it.
