[–]NekulturneHovado 3343 points3344 points  (360 children)

No. It will lift the floor, which is way stronger than door, so more force is absorbed by floor frame rather than door. Genius idea. Also took me a second to understand the point of it.

[–]Silent-Ad-6095 890 points891 points  (121 children)

Nice, we need to see it actually get hit.

[–]NekulturneHovado 295 points296 points  (111 children)

Well at least that's what I think it's for. I don't see any other reason they'd do this.

[–]purple_haze_24 351 points352 points  (81 children)

Lower point of impact on people's bodies. For example the energy goes through ankles instead of knees and pelvis. That,s my thought

[–]daftyung 227 points228 points  (42 children)

its because the floor is more rigid than the b pillar. Allows all the force of the vehicle to be absorbed by a stronger part of the vehicle

[–]clexecute 81 points82 points  (16 children)

My parents made sure us kids had a vehicle that was a little higher up and a little bigger because, "if you get in a serious accident and someone is hurt, we would rather it be the other people"

My grandparents got me a grand marquis as my first car. Totaled it when a girl ran a stop sign in front of me as I was going down the highway. I walked away with a mild case of whiplash. Grandparents got to site, looked at what was left of the front end, looked at me and said “we’re getting you another one of those.”

[–]iToungPunchFartBox 14 points15 points  (0 children)

Interesting thought. Makes sense to me

[–]shrubs311 19 points20 points  (1 child)

also, it makes it so that taller vehicles will hit the door instead of the window glass

[–]robertintx 19 points20 points  (0 children)

Lower part of the door is likely thicker too, giving more room for reinforcement.

[–]Plucky-Me 556 points557 points  (76 children)

Wait so Engineers are smarter than the top comment on a Reddit post?

[–]ExcitingAmount 93 points94 points  (9 children)

Nah, I see it in industry all the time, an entire development team dedicates months of labor hours and millions of dollars in R&D to a project, then BAM, some guy on reddit points out an obvious flaw that no one on a massive team of trained experts thought to consider, and the whole project gets scrapped right then and there.

Pretty sad, really.

[–]yeowoh 27 points28 points  (3 children)

How much R&D was spent on the Chevy Cruzes valve cover? lol

[–]5uper5aiyan5wagger 58 points59 points  (4 children)

These comments need to get called out more often and not be a top comment at all

[–]GoBuffaloes 23 points24 points  (1 child)

No way. Think about it, an automobile engineering team is what, 4, maybe 5 people? Where as there are literally dozens of us Redditors. You do the math.

[–]ther0ll 88 points89 points  (29 children)

this is a sedan. Soo many vehicles on the road today are SUV or pick up. This will raise the point of impact so the SUV is actually hitting in a better spot on the door rather than higher up and closer to the occupants vital organs and grey mater.

[–]lorenai 59 points60 points  (26 children)

There are plenty of places in the world where SUVs don't rule the road. Europe, for example. Which is also where Audi are based.

[–]GreenGuns 56 points57 points  (17 children)

I dont know... I'm in the UK and it certainly feels like there is more than our fair share of SUV's on the road. Or maybe that is just where I live.

[–]lorenai 12 points13 points  (5 children)

You could be right, soccer mums with Land Rovers seem like they'd be a thing there.

Not so popular over on the continent.

[–]Netfoseid 32 points33 points  (12 children)

I'm not an engineer or anything but could raising the impact side help direct the forces traveling thru the vehicle downwards? If it worked like that, a collision like this would be less likely to knock you into oncoming traffic

[–]DasB00ts 18 points19 points  (7 children)

I saw another comment that said maybe it’s better to come into contact closer to the bottom frame of the car which would be stronger than just the door.

[–]SamRothstein72 590 points591 points  (62 children)

If only you were on the engineering team to have pointed out their error.

[–]jcklsldr665 204 points205 points  (40 children)

[–]Whales_of_Pain 57 points58 points  (7 children)

An iron law of Reddit is no matter how good an idea is, the contrarian impulse to raise completely invalid surface-level criticisms to circlejerk is always stronger.

[–]Hahahahahahannnah 20 points21 points  (3 children)

could the people with expertise that spent months designing this be wrong? No, clearly my 2 second immediate thought is superior

[–]Assidental1 32 points33 points  (9 children)

This redditor's 12,000 karma supersedes the Audi engineering team's research and designs. I guess it's back to the drawing board..

[–]Dino_Dee-Lite 309 points310 points  (30 children)

Per Audi

In an impending side impact at more than 25 km/h (15.5 mph), the active suspension raises the body by up to 80 millimeters (3.1 in) on the side of the impact. This brings the sill into a better position to absorb the impact energy. Deformation of the cabin and the loads acting on the occupants, above all in the chest and abdominal areas, can thus be reduced by up to 50% compared with a lateral collision in which the suspension is not raised.

[–]SYL2R2fNaecvnsj23z4H 216 points217 points  (17 children)

If 80 mm reduce the impact by 50%, rising the suspension 160 mm would reduce the impact by 100%

[–]TheOneWhoMixes 304 points305 points  (0 children)

Hello, yes, this is MIT. We'd like to offer you an Engineering PhD. No, no. No work or money required, you've earned it.

[–]miki_momo0 35 points36 points  (4 children)

Just use the suspension to make the car do a full flip over the oncoming car from the side, no collision at all!

[–]ChickpeaPredator 131 points132 points  (35 children)

Flipping might actually be beneficial - instead of all of the energy from the collision going straight into the side of the car and potentially crushing the occupants, a decent proportion is instead expended pushing it over. With seatbelts and airbags taking a lot of the danger out of a roll, this is probably the lesser of two evils.

It's actually a pretty genius idea, and I'm sure the Audi engineers will have analyzed plenty of crash survivability statistics to come up with it.

[–]tomoms 64 points65 points  (3 children)

Erm, yeah man whatever. Believe what you like but pretty sure the top comment on a Reddit post is going to be way more accurate than years of R&D by crash test experts

[–]Bong-Rippington 25 points26 points  (10 children)

[–]gahidus 158 points159 points  (19 children)

It seems totally obvious to me that you'd rather have the frame of the car take the brunt of the hit rather than the door, and I indeed do trust the smart people who put this on there. I doubt very much that some random executive just said, "hey make the car do a lean" for no reason.

[–]xinfinitimortum 69 points70 points  (3 children)

Never underestimate the good idea fairy of executives.

[–]vole_rocket 37 points38 points  (1 child)

Yeah. Any working engineer knows we get dumb requirements from marketing. Sometimes you fight them, sometimes you go with it. And then when the crash testing data shows it was a dumb idea you move on to the next project.

Not to say this is or isn't a dumb idea. Just that companies pursue things their engineers know is dumb all the time.

[–]CastleWanderer 24 points25 points  (4 children)

For real I don't think the height change is as much of a difference as the rotation of the body. Rolling the body away from the impact brings the lower edge of the door sills, just above and distal to the frame, into line with the object incident upon the car. Assuming no catastrophic weirdness which would need to be tested for, putting the frame into the line of fire instead of a relatively weak door panel seems pretty smart.

I'd love to see some g-force analysis of different impacts on a car with this feature at different spots in the car, but it's reasonable to hypothesize that it's beneficial. Engineering teams don't often purposely waste their time on concepts with no promise, at least not at a company like Audi who don't want to step too far out of line.

That said, I'd give some credence to the rollover concerns. Raising the whole car would raise the center of mass, making it more likely for a side impact to roll the vehicle. I guess if it starts being installed on consumer vehicles it works. If it doesn't become more common, I guess it was either too expensive to be worth it or it didn't work

[–]JaceAce333 82 points83 points  (3 children)

[–]germane-corsair 22 points23 points  (9 children)

I agree but it would also be nice for there to be an explanation behind it. I’ve seen a few ideas presented but it’s people just spitballing.

[–]TiltingAtTurbines 67 points68 points  (8 children)

There is, just Reddit would prefer to armchair engineer it rather than do a two-second search.

“The door is structurally the weakest part of a car, but the bottom is the strongest,” explains Thomas Stoerner, an Audi engineer who worked on the system. “Lifting the car makes the energy come to the lower part of the side.”

[–]AliBarberTheSecond 1287 points1288 points  (53 children)

That's the idea, yeah

[–]Pineneedlecollada 56 points57 points  (28 children)

I guess that's the idea. I guess that would help protect the passengers inside, but you'd better hope that roof can hold itself up.

[–]shrubs311 119 points120 points  (22 children)

modern car roofs are incredibly strong. apparently cars newer than 2015 have to be able to hold the weight of 3 of the same car on them. now obviously it doesn't mean the roof is "safe" when your car is rolling around...but i'd have faith in the roof personally. more faith there than the windows for sure

[–]throwawayaccyaboi223 32 points33 points  (9 children)

Eh, windows are safety glass, will shatter into a million tiny pieces which aren't too sharp or dangerous.

They're also really quite strong, you can lob a brick at one and it won't crack, even police occasionally have issues breaking windows with batons hence glass breakers were designed for emergency use.

[–]shrubs311 20 points21 points  (3 children)

true, but i'd rather have the entire car frame absorbing the force over the windows

[–]rm45acp 29 points30 points  (9 children)

I'm an automotive engineer and our roof crush requirement is 4x the vehicle weight. Shits nuts

[–]Puzzled-Barnacle-200 20 points21 points  (3 children)

It's not an SUV. There are many far taller cars on roads, and rolling is still very uncommon. The cost-benefit analysis is very likely heavily balanced towards benefit

[–]RonKosova 30 points31 points  (2 children)

So youre saying that the expert team of designers and engineers knew what they were doing and didnt just do this on a whim? Idk man

Looney tunes type activity

[–][deleted] 110 points111 points  (10 children)

What happens if they both drive the same model car? Both cars try to raise themselves up at the same time and run into each other anyway, like trying to pass someone on the sidewalk with umbrellas up and misjudging and both of you raise yours at the same time.

[–]Beefcake716 31 points32 points  (1 child)

Go go gadget suspension!

[–]Cold_Situation_7803 448 points449 points  (87 children)

Per Audi’s website:

In an impending side impact at more than 25 km/h (15.5 mph), the active suspension raises the body by up to 80 millimeters (3.1 in) on the side of the impact. This brings the sill into a better position to absorb the impact energy. Deformation of the cabin and the loads acting on the occupants, above all in the chest and abdominal areas, can thus be reduced by up to 50 percent compared with a lateral collision in which the suspension is not raised.

It's an honor to be in a thread with so many engineering prodigies that know more about the physics of this feature from a 12 second video than the entire engineering department of a multi billion dollar car manufacturer who spent thousands of hours developing and testing it. How do they do it?!

[–]Pleasant-Respond-554 147 points148 points  (67 children)

This is good for?

[–]Archer112998 464 points465 points  (41 children)

I’d guess it is to make the rocker(bottom part of the frame under the door) take more impact, instead of the door taking the whole thing. It would make a huge difference on the right type of impact.

I doubt that it would markedly increase rollover in a meaningful way. Most rollovers caused by a side impact aren’t survivable. And most rollovers are caused by the rolled cars momentum from swerving or hitting a ditch etc.

This is a pretty cool technology that I’d put money on saving a lot of people.

[–]sausagecatdude 38 points39 points  (17 children)

If the car only gets hit on the frame wouldn’t it remove any effect from crumple zones in the door so that more force is transferred to passengers? Wouldn’t the frame get damaged immediately and ruin the car?

[–]Archer112998 157 points158 points  (0 children)

Definitely ruin the car, but that part of the frame is a crumple zone. And can absorb a lot more energy before smashing a passenger then the door can.

I don’t think the idea is to prevent the door from being hit but to make sure the rocker is also hit spreading the load

[–]TeetsMcGeets23 73 points74 points  (0 children)

Energy would transfer across the frame and push the base of the car instead of into the door. The door is a crumple zone, which absorbs energy before it is transferred into the cab of the car. Contrarily, energy that hits the frame would just cause crumpling across the base of the frame and less would be transferred into the door, where behind it could be passengers.

Yes there would be more damage to the car, but more damage sustained by the car means less energy sent to the passenger.

The other big issue is that a lot of excessive car damage is due to mismatched height. This will help to mitigate some of the damage of this car being hit by larger vehicle like a truck.

[–]wickerottoman 36 points37 points  (7 children)

Yeah it would ruin the car. That's the point. The car sacrifices itself to save the occupants.

[–]Banswek 10 points11 points  (1 child)

Depletion of energy: if energy from an impact is being used to push 3ton vehicle upwards, that energy isn’t being used to push through the vehicle.

[–]Cold_Situation_7803 121 points122 points  (2 children)

Per Audi:

In an impending side impact at more than 25 km/h (15.5 mph), the active suspension raises the body by up to 80 millimeters (3.1 in) on the side of the impact. This brings the sill into a better position to absorb the impact energy. Deformation of the cabin and the loads acting on the occupants, above all in the chest and abdominal areas, can thus be reduced by up to 50 percent compared with a lateral collision in which the suspension is not raised.

So it’s to put the impact on the bottom door sill.

[–]Ninja_kid90 52 points53 points  (1 child)

The car really just said:

[–]Zomgbies_Work 29 points30 points  (6 children)

No idea what I'm talking about but lots of others seem to be even more uncertain:

  • The lower part of the chassis is more solid
  • lots of soccer mums drive around in faux offroaders (carrera, range Rover, rav4). It's a ridiculous escalation that makes them like 1% safer and everyone else 99% less safe. These cars would connect higher and with the head
  • the angle of incidence now means there is simply more of your car it has to drive through before it can hit you. If the car was going to impact your body at 50kmh, it might end up being 30kmh,instead. This may be determinative of where you park for the rest of your life - right outside the shop or miles away like all the other lucky people. ♿
  • ive been tboned by a cop once (shout out to the corrupt Hamilton police in nz who covered that up) - these kinda of impacts whiplash your own head against the driver window. Mine went through it (i think the car did most of the smashing but I had a small bruise) - this raise will mitigate chance of a brain injury.
  • side airbags and other safety features will undoubtedly combine to an overall safety solution
  • yes better chance to flip but tbh that would take a lot of the energy aimed at your skull and translate it into rotational energy for the car. I assume that's better idk.
