The 2018 Audi A8 can react to a potential side collision by lifting it's side to protect passengers

Wouldn't that increase the odds of a rollover? I'm assuming the engineers did tests, but still, I'd be worried if my car had that feature.

u/Suave_Jelepeno Aug 13 '22
The act of a rollover means much of the force is transferred to momentum instead of crushing the passengers. I'd take a rollover compared to the alternative.

I suppose as long as the roof is relatively strong

u/BabbitsNeckHole Aug 13 '22
All cars in America are mandated to be able to support themselves in the case of a rollover. Even convertibles. This lead to larger blind spots so now backup cameras are mandated also.

u/The_Gray_Beast Aug 13 '22
Interesting. I look at auction cars when I am bored and I saw a nice f250 literally plastered in blood with the roof caved in
Wonder what happened there. Id imagine it’s not only it’s own weight that is the issue

u/New-Ad-5003 Aug 13 '22
Heavy duty trucks often do not have to comply to typical auto regulations, such as emissions, and probably safety too.

I think lowering the point of impact (relative to the audi) is also beneficial. The doors, door beams, and roof are relatively weak compared to the structural members of the floor. By tilting it’s bringing that point of impact lower and closer to the chassis and the strongest structural bits so that more energy of the impact goes into shoving the car rather than crushing it.

u/p4r24k Aug 13 '22
the key part here is "to the audi"... screw the motorcycle rider

u/xlRadioActivelx Aug 13 '22
If you’re on a motorcycle and t-bone a car at those kinds of speeds, you’re having a real bad day no matter what.
I don’t think the tilt makes really any difference to the motorcyclist. The tilt moving the point of impact closer to the strongest structural members of the car would reduce the amount of crush-zone, making the impact happen over less time therefore higher G-forces. However, the motorcyclist is not rigidly attached to the bike, the G-forces experienced by the bike don’t really mean anything for the G-forces experienced by the rider (above a certain point). The rider is going to keep moving forward after the impact until they hit their bike, and probably the car after that.
In other words hitting something relatively soft like a car and hitting a solid brick wall are very different for cars, the occupants of a car, and the motorcycle itself, but less different for the motorcyclist.

u/p4r24k Aug 14 '22
but the car is now taller for the biker, therefore, more chances that their flight gets intercepted by the car.
1
u/xlRadioActivelx Aug 14 '22
The car is already 5’ tall, the rider is almost certainly going to hit it, an extra two or three inches isn’t going to change that. Besides if you’re going fast enough to fly over the car, and quite likely into traffic, you’re having a real bad day and hitting the car doesn’t seem much worse.

Perhaps. But this reduces the chance of something coming in through the window. Which is arguably worse

Still now costs more to fix a car than is worth. Cars like these are theoretically worthless now unless you’re upper middle class at the very least and that’s being general

Don't worry, your crumpled mass of steel will be slightly higher on the right after said crumpling.

u/CDavid2005 Aug 13 '22
I'm almost positive a roll-over impact is signicantly less dangerous than just tanking a hit to the face or side of your car, so I'd much rather prefer this system.

u/No_Reaction7902 Aug 13 '22
It depends on if there is cab intrusion or not, but a truck slamming into the side right into both doors is a worst case scenario, and this feature could save your life if it caused a rollover instead of the cab of the car crushing and stabbing you
2
u/CDavid2005 Aug 13 '22
Yeah exactly. A cab intrusion is the short end of the stick, and from what I've seen you only see so many freak accidents in your life, most of which are not caused by sane, sober, and safe drivers, so I'd like to think my chances are very good lol

Depends on speed and if everyone is wearing a seatbelt and there is nothing in the car that will become a projectile. If this results in a rollover when the car wouldn't have been in a bad accident then that is not good for anyone involved.

Better would be some sort of reactive armour to neutralize the threat.

u/ours Aug 13 '22
Or active protection like for tanks and armored vehicles where it automatically blasts an explosive at threats in short range. Might make insurance cases... interesting.

u/xSnakyy Aug 13 '22
It’s kinda what it does. It makes it so the impact is on the harder and stronger chassis and not on the body which is much weaker

u/RandoKaruza Aug 13 '22
It just seems that designing the car in such a way that the impact zones can actually be impacted without sophisticated proximity sensors would be a more elegant approach
3
u/RacerKaiser Aug 13 '22
That would require a bar to be in the middle of the door. So you would be climbing through a window. That’s what race cars do, not luxury sedans.
0
u/RandoKaruza Aug 14 '22
Side impact bars create deformation zones in just this way while allowing full ingress and egress. this tilt won’t do much for a full size SUV… but it does look cool… which is what luxury sedans are for I suppose so it’s quite on brand.

u/Jaripsi Aug 13 '22
I dont get what you are suggesting. This seems to be a pretty elegant solution already as it doesnt require anything added to the car but a piece of code if the car already has 360 degree parking cameras and air suspension.

Only in America, in Germany it’s quite a bit different. But again, they have great public transit that isn’t just designed for the poors.

u/W0lfwraith Aug 13 '22
LOL nice way to get flipped if it’s anything larger than a sedan.

u/theultimatecat07 Aug 13 '22
Better than being crushed

u/W0lfwraith Aug 13 '22 edited Aug 13 '22
Not always no. Vehicles are designed to crush around you not into you. I’d rather be trapped with a broken arm/hip than be a qudraplegic.
Editing: upon some reflection I realize I am wrong. I’m a bit stoned and need to remember to keep my mouth shut when that is the case.

u/zackson76 Aug 13 '22
Rolling make the momentum from impact get transfered over a wider/longer vector, thus reduce impact. What would hurt more, punching a dangling sandbag or a brick wall?

Yes, I am well aware of what crumple zones are. I mean what the hell are you talking about specifically here with broken arms and quadraplegics?
1
u/W0lfwraith Aug 13 '22
What I’m referring too is that I’ve seen more than a few collision aftermaths and a full on T-bone that sends a car rolling more often than not does more than break bones. I used a rather poor comparison to try and make that point and I apologize.

u/PM_ur_Rump Aug 13 '22
Some people say steel toed shoes are dangerous because the steel toe cap can cut your toes off if something very heavy is dropped on them.
This is true, at least the second part.
But dropping something heavy enough to bend the steel would more than crush your fleshy little toes. See where we are going?

u/JonLongsonLongJonson Aug 13 '22
There are no crumple zones on the sides, though. They’re the biggest weak point. This reduces the chance of getting crushed.

u/GrindMagic Aug 13 '22
Maybe safe for the Audi driver but not so much for the poor old lady in the Camry that ends up going underneath it. 😳
3
u/Jaripsi Aug 13 '22
Collision to the side is usually less safe than a head on collision as the front of the car has lot more crumple zone than the sides. Even with this trade off the old lady in the camry is better off.

u/Straight-Knowledge83 Aug 13 '22
How does one go underneath an Audi in a Camry?
1
u/XsniperxcrushX Aug 13 '22
I'm guessing the Camry crumples down close to the ground while the audi is tilting upward so that the Camry slides under the Audi before if/can roll over.

How about just building a car from steel again that could actually take a hit and little just pop it out later with a hammer. Watch a modern car hit or get hit by an old car, the steel cars walk away usually in better shape

u/PBAHA97 Aug 14 '22
Yeah but this feature will not be available to non-premium user in the coming years. You'll actually have to perform a micro transaction to access this safety feature. You'll have 0.0001 of a second to to say yes before another car hits you.
