watch the intro video in the film section, its amazing

do you still believe in santa claus?

Dark_Knight

ummm no, but I believe some of porno is real and sometimes women can be nice to you

Thanks for sharing the interactive AMG site. Very cool. I believe it is all editing that makes the SLS appear to defy gavity

tasho3

its old and its fake, i watched the making of this video, and they had a small scale model where they did the editng, but i heard Gumpert is trying to do this in reality but can not find a dumb enough driver to drive the car upside down lol

The SLS video is just a publicity stunt by MBZ. The only car that can theoretically drive on the ceiling would be a Formula 1 car. Minimum weight to compete in a race is 1334 pounds, which includes the driver and fluids. The aerodynamic devices on a F1 car generate in excess of 2000 pounds of downforce, which would make this feat possible. The hard part is finding someone to make that stunt, as it would have to be done at a very high rate of speed in order to work.

Incorrect......

"Saleen happily declares that the S7 is the most aerodynamically efficient street car ever built. For the S7's early development, his team spent two months testing in Scotland at the University of Glasgow's wind tunnel. He says the S7 body makes so much downforce that the car can drive upside down in a tunnel at any speed above 160 mph. Yet, he adds, the shape is slippery enough that the car can reach redline in sixth gear, which works out to 223 mph, although that's a figure we did not confirm on the track."

I stand corrected....... until you buy an S7 and perform that stunt personally

BTW, you missed that I said theoretically

mr inkredibul

I can see why one might think this is real though.

503C43 ////AMG

well theoretically you were incorrect .... I'm just kidding, I just remembered reading an article a long time ago about the S7 and when you made the statement about a car driving upside down I recalled the article. You couldn't pay me enough to even attempt driving upside down regardless of what any scientist or engineer claims a car is capable of.

Count me in...I'll drive the SLS, if I complete the tunnel stunt, can I have the car?

A NEW car in case I "accidently" destroy the test car

503C43 ////AMG

Well according to the specifications of the deal you would need to complete the tunnel stunt and if you "accidentally" destroyed the car I don't think we could consider that a successful attempt but I would LOVE to see you try

allenc63

You MUST be an attorney....for MB

Kidding. I would LOVE to TRY

Yuille36

Does anyone know why this stunt has never been attempted?
Because, they can't find a dumb A** stupid enough to try it.
Maybe the guys from jacka** might try it.

Have you ever tried to run an engine upside down? A lot of stuff breaks haha.

For the record, my track car flipped years ago when it was lent out and the engine was running upside down for a bit. Whole top end needed replacement once we got the car back together.

Gravity's a *****.

Video is definitely not real but very cool nonetheless. I'm not sure finding a driver is the issue, there's always someone out there who will try it. I think the fear of being sued to oblivion when something happens to the driver is more probable

People are doing these kind of ridiculous stunts on motorcycles and skateboards, its just a matter of time before they find the right idiot to sign the dotted line of the insurance waiver Either way it will be good as we will all laugh or have our jaws hit the floor, I'm down for either of the 2.

Your physics is wayyyyy off. You don't need to generate downforce if you're just temorarily rotating within a tunnel. You can use the centrifugal force of an object to momentarily plant you to the inside of a tunnel.

Cool video. I love the sound of that car.

SMP

How did you study physics, when you have an obvious handicap in reading?

Read my post again: Not only did I say "theoretically", but also "driving on the ceiling". It depends on how you look at it, but I guess we're both right. Centrifugal force gets you there, and downforce will keep you there

firstbite

No physics needed, just go with it. The Stig could do it.

e1000

If you read back on your combined first and second sentences, they clearly reference the SLS video and therefore it can be understood that the SLS maneuver is in question. Yes if you wanted to stay inverted on the ceiling of a tube, you would need to generate downforce greater than the weight of a given car. The video however, clearly shows a momentary rotation within a tunnel, and for this type of movement, no downforce is necessary.

NickZag

I'm dumb enough, I'd do it

The Gumpert Apollo can also be driven upside down. I dont know who would be crazy enough to do it, but given the wing adjustment, it will generate enough down force to drive upside down at very high speeds (190+MPH).
