This is the one that we get a sneak peak of in the trailers, when Whiplash cuts Tony’s car in half, and Tony

dons the suitcase suit! OMG, I think I need a change of pants! We get the full sequence of him putting on the suit, and a little of the ensuing fight.
Now, as expected, it falls victim to the “hammerspace” cliche. There’s no way that much suit is in that suitcase, unless it’s only about 1/8" thick all around…but I don’t care! It’s awesome! And besides, what’s better than a comic book movie that’s faithful to the source material? That’s how it worked in the comics, so dang it, that’s how it will work in the movie! Don’t ask too many questions!
I’m not saying the suit is realistic, but I don’t think the case would be all that heavy, given that the suit is probably a futuristic alloy and the suitcase armor version is a stripped down and is obviously very thin version of the standard suit.
A suit of plate armor can weigh as little as 45 pounds according to Wiki, so a modern composite should be way lighter. And it doesn’t have batteries, since it’s powered by Starks chest reactor. So all it needs is a trillion minimotors that allow it to unspool, some repulsors and bam, 25 lb suitcase of doom.
I was more bothered by the fact that super-electro whip man was sitting around tapping his foot for the 25 seconds it takes Tony to get his super suit on. A smart villian would just whipped his face off while he was bending over to hit the “on” button.
There must be an entry on the Evil-Overlord list about not sitting there gawking while your opponent takes the eight minutes necessary to ready his super-attack.
Forty five pounds seems a little light. Steel has a low end density of 7.75 grams per cubic centimeter (cite). Forty five pounds equals 20,412 grams. The average body surface area of an adult male is 1.9 square meters (cite). 20,412 grams distributed over a surface area of 19,000 square centimeters equals 1.07 grams of steel covering each square centimeter of body area. Which is just 1.38 millimeters thick. That’s less than 1/16 of an inch.
Now assume instead Iron Man’s armor is a quarter of an inch thick. That’s .635 centimeters. Over a surface area of 19,000 square centimeters that adds up to 12,065 cubic centimeters. Assuming it’s mostly steel (after all he’s Iron Man not Captain Composite) that’s 93,500 grams, which is 206 pounds.
He wasn’t just sitting around. He was, from what I can tell, blasting the crap out of the car Pepper is in. You can see him on the other side when Stark kicks the car away. I don’t think Whiplash actually saw Tony don the armor.
Well, it started out as calculations over plate armor.
Gold-titanium alloy is a tough one. The density of gold is 19.3 grams per cubic centimeter. Titanium is 4.5 gpcc. So, depending on the mix of the alloy, my theoretical quarter-inch full body armor would weigh somewhere between 54.3 to 232.8 kilograms (119.7 to 513.2 pounds).
It might not have taken as long to don the armor as it looks. When we see the arm pieces sealing up and then see the leg pieces sealing up, I imagine that those are both happening at the same time.
But even if it takes half the time, we’re still looking at twelve seconds or so where evil whip man appears to be just hanging out watching why Tony gets ready to fight him. Course maybe there’s a plot reason for this, or the actual movie will be cut differently, so its kinda silly to nitpick just the trailer. I’ve just been noticing that kind of stuff in movies recently (not that its a recent development in action films, I’ve just started watching for it for some reason) and its been bothering me. The camera will focus on the hero during a fight, and he’ll stop to do some heroy type stuff (get ready to unleash his super-power death move, exchange a long romantic glance with the heroine, figure out what button he needs to push on the mulligan, etc) and then the camera will zoom out and we’ll see that the villian standing a couple feet away just waiting for him to finish.
Period armor on the torso was about 2mm thick but in any case, no primitive armor actually covers the whole body so some allowances have to be made for that of course.
As said above below, the armor is a futuristic composite, not iron. Also, a quarter inch on the pared down suitcase suit may be overstating it a bit, it appeared fairly thin.
Well we know that it isn’t actually just a gold-titanium alloy, since that likely wouldn’t be able to shrug off the damage he’s seen to be taking. It would be reasonable to assume that the material is some sort of super-science composite that is referred to as gold-titanium as a shorthand. And we know that since there is a handle, it must be light enough to carry around in one hand.
I can’t be sure, but it looks like Stark’s bodyguard rammed Whiplash with his car and pinned him to a wall. Stark kicks the car off him and the fight begins.
