Can this actually be done?

[Savvy]

If so I want one!!!!

I doubt it IMHO, however, I agree.........I want one!

Course its theoretically possible, its just centrifugal force. An F1 car can theoretically drive upside down on the underside of a tunnel, due to the huge ammounts of downforce they produce. All you need is a long enough and smooth enough tunnel and a suicidal driver.

What a disgusting colour for such a beautiful car. Anyone who knows their motoring history will tell you that a fast Mercedes should be Silver...

Please do not use a force that does not exist to explain one of the many flaws in gravitation!

didn't they do it on Top Gear?

ok the car might not be as good and jezza didn't make it look as good but stil...

No he technically never did it, because of the force of gravity and the car was already forcing itself to one side, its curious that it only returned on all 4 wheels by chance, the physics behind that happening again would allow someone with enough speed to drive on the underside for about 0.8 seconds but would most definately be in a 1 in 100 chance of landing on all four wheels, no car (including F1 cars) allow any amount of downward thrust to do such thing while the laws of gravitation exist. To do a loop de loop similar to that of size to roller coasters is possible.

Google it, and F1 car does produce enough downforce to theoretically be able to drive upside down in a tunnel.

Oh and its reacive centrifugal force for the merc

In a Vacum where no other force exists it would be possible yes, but no such place exists (otherwise you couldn't breathe) due to reactionary forces, if somehow a F1 car did start upside down by such technology that does not exist today it is possible, however to start off the ground and climb up the lateral 'walls' the reactionary force would reverse itself so the downward force would be reversed as it drove upside down to allow it to stick to the cieling, The downward force would act with gravity due to the time taken to climb to the cieling (even if it was a tenth of a second) so to do it in a similar fashion of the merc, it would be possible to the same extent of the Top Gear incident, but it could not begin driving upside down for as long as it wants as it would just fall to the ground.

F1 cars have 'wings' that allow the downward force (like an upside down airplane wing) to act with gravity to allow the huge downward force, so when turned upside down it does not act against gravity as an 'upward' force. its the same as applying the situation to an airplane, that if it turned upside down it's lifting force would be applied with gravity and fall to the ground, its purpose is to act against gravity and planes can in effect fly upside down.
