It is perfectly possible, what point dont you understand?

I've seen things you people wouldn't believe.

Anyone who has ever been diving understands that this is theoretically possible, as long as there is enough compressed air in the tires. As someone else points out, it's all about water displacement.

Not to mention he was drifting, doing burnouts, and maneuvering at high speeds with the very same deflated the tires.

It doesn't make any sense at all! If the air in the tyres was able to create sufficient bouyancy to raise the car to the surface, they why didn't it just float anyway?

Why would taking that body of air, from the car, and putting it in a bag, attached to the car, be any different from just leaving it where it was?!

I just enjoyed it for what it was, but yeah: dumb logic. Rob Knepper was the best thing going in this movie. I'm excited coz I get to work with him soon :)

Put the air in a lead cube, see how that goes.

The air in the tires is compressed. When released it provides more buoyancy than when in the tires.

Now I'm not a math guy, but I'm guessing you can calculate how much compressed air is in 4 tires, then calculate how much buoyancy that provides, and compare it to the weight of the particular Audi used in the film. It more than likely wouldn't be enough, but dismissing the movie right off the bat w/o any info is a dickish move.

Seeing as it's a Transporter film, and Frank Martin routinely beats the crap out of groups of hoodlums, I'm inclined to take this with a grain of salt and say it's no more outrageous than some James Bond scenes.

the surface area of the bags/balloons also plays a part

I don't know about particular tyres - the pressure used on this index / suspension etc. - but on average car it's about 2 at/1.96 bar/28.44 psi. To put it simply, air released from them would only double by volume. Even more simply, 8 low profile tyres on normal pressure should give enough buoyancy for 2 - tonne Audi A8 to float?

No way.

This is a movie for kids and adult admirers of this kind of kitch carnival to have fun watching. Laws of physics and logic are elegantly sacrified for sake of fun.

911 also broke a butttload of physics law but people still believe in it

There's an easy way to visualize this without doing the math and see that it could make sense. If you were to take the tires and fill a bag (or bags) with air from the tires, how big would they be? No need to answer, just visualize it. Now take that same bag (or bags) and imagine that size filled with water instead of air. Then think about how much they would weigh. Would they weigh more than the car? If so, the car floats.

It's all about displacement.

If the volume of water being displaced weighs more than the object to displace it, the object will float. This is why compressed air makes a difference. It's not displacing as much water as if it wasn't compressed.

This classically follows Boyle's Law, P1V1=P2V2(assuming amount of air and temperature is constant). Remember the air in the tire is Above atmospheric pressure(1 ATM = 14.7 psi), so this must be added to the equation.

I just realized I have way too much time on my hands......

So in the next movie, he'll fill his tires with helium and it'll fly?

This looks like a good one for the Mythbusters team...

[–] throcko1 14 years ago

This makes sense--when I saw that scene I didn't think about the compression factor. Still, there wasn't enough air in those tires and it would have escaped by the path of least resistance (which would have been out of that bag, not by lifting the car).

reply

[–] Rounin1 14 years ago

Just calculated everything. Considering T=const and that there was no pressured air lossage, the force that acts downwards is roughly 18,75 times greater than upwards so the car definetly should have sunken.

Incidentally Jason Statham is a world champion class diver. So a stunt like this is either complete baloney or actually possible. I believe it's the latter.

reply

[–] iamhomercles 14 years ago

If you believe the physics in this film, Statham could swim down to the titanic breathe into a couple of carrier bags and raise it to the surface. Its a comic book movie though, it is not supposed to be realistic.

Laws of anything....? Naaaaaah.

If it was just the physics that sucked, I could live with it, but almost everything else was so horribly bad as well...

[–] jsusna72 13 years ago

Why did he even bother floating his car to the surface anyway? Maybe it's like a Labrador retriever and it will just shake itself dry and he can hop in and drive it away.

Seems possible. More so than calling someone while beeing under a few meters of water... but cell phones ALWAYS work in movies except when the plot demands otherwise...
