'09 Malibu Vs. '59 Bel Air Crash Test
theodp writes "To celebrate their 50th anniversary, the Insurance Institute for Highway Safety crashed a 1959 Chevrolet Bel Air into a 2009 Chevrolet Malibu. Hate to spoil the ending of the video, but if you find yourself participating in a similar car-jousting contest, pick the Malibu over the Bel Air. (Not that you'll be complaining afterwards if you don't, or doing much of anything.) Guess there is something to those crumple zones after all."
Why would the pointlessly ruin a 1959 Belair? It's not like they make those anymore.
All I can say is "You bastards! You murdered a car with tail fins! Have you no heart?
Right around that year GM went to a wild X-frame design which allowed the door sills to be moved down several inches, making the cars easier to step out of. But the X was not very strong-- there were plenty of news photos showing Impalas broken in half by not very hard accidents.
Also if you look at a 50's car, the bumpers are massive but held up by a couple thin pieces of mild steel stock-- a strong toddler could bend them out of place.
Now this is a story all about how my life got flip turned upside-down. I'd like to take a minute, just sit right there, I'll tell you how I totally destroyed a classic car in the name of science.
Funny may not give karma, but +5 Informative never made anyone snort coffee out their nose.
The comments on the video are rather telling. A number of people claim the video must have been faked, because "The Chevy would have barely gotten scratched."
Notably, a number of the panelists on the hearing about the sinking of the Titanic expressed serious doubts that mere ice could have torn iron. In other words, time marches on, but ignorance of physics remains a constant. (Also see, "This is the first time in the history of mankind that fire has melted steel.")
Actually I am a lab rat in an elaborate plot to take over the world.
A recent TopGear did something similar: they crashed an NCAP (European crash standards body) 5 star+ rated (the highest rating) car (Renault Espace) into an earlier model of the same car (a 1998 Espace I think it was) at 35 mph.
The crash investigator they had evaluate the results said the driver of the older car would have had multiple broken bones, including both femurs, and even if he'd survived the crash he would have bled to death by the time they could extract him, which would take 30-40 minutes as the car was so badly deformed.
In contrast, the modern Espace's computers decided the crash wasn't bad enough to deploy the air bags! Only the seat belt pre-tensioners fired. The investigator thought everyone in that car would have walked away from the accident uninjured.
Their conclusion was that modern crumple zones and stiffer chassis work but because they are stiffer older cars suffer much more when colliding with a modern car.
What always surprises me is how much damage is done to any car, old or new, at these low speeds! Really says to me that any speed limit over 40 mph on any single-carriage way road is just insane.
Bad analogies are like waxing a monkey with a rainbow.
A few people were calling shenanigans, claiming there was no drive train or that the IIHS used a vehicle with a rusted out frame.
So a writer for the NY Times caught up with "David Zuby, the senior vice president at the institute's crash-test center in Virginia"

o0t!
Top Gear tries to stay away from useful facts and info as much as possible.
And the idea of Top Gear having TWO cars that cost below $40,000 on the screen at the same is pretty far fetched.

One reason that the door crumpled so readily is the crazy wraparound windshield. The windshield pillar contains a free-hanging right angle, which is not the way that a structural engineer would have done it. It also bangs the knees.
The big problem with older cars is that the body shape was sculpted from clay in a studio separate from the rest of the car designers, rather than being designed as part of an automobile. The end result being that the body shape had no basis in sound mechanical design.
The determined Real Programmer can write Fortran programs in any language.
and that cars should have a spike on the steering wheel reminded me of an old Letterman top 10... thank you, Internet!
Top 10 Ways American Cars Would be Different if Ralph Nader Had Never Been Born
10. Dashboard hibachis
9. Seat belts made of piano wire
8. Windshield replaced with ant farm for kids
7. Strobe headlights make oncoming traffic look like old time movie
6. 50-foot antennas allow you to broadcast while driving
5. Optional front-seat hammocks
4. Wiper fluid reservoir routinely filled with thousand island dressing
3. New York City taxis would be exactly the same
2. The paper Buick
1. Speedometer replaced with electronic voice chanting "Punch it! Punch it!"
Literalism isn't a form of humor, it's you being irritating.
My friend, many motorcyclists care deeply about their bikes, but that does not prevent surgeons from referring to them as "organ donors".
From scarped cliff or quarried stone she cries "A thousand types are gone, I care for nothing, no not one."
And why do they collide at an angle, because that definitely favors one style of construction over another - frame, engine placement, driver's side vs. passenger side, body materials, bumpers, etc.
Because in the real world, cars collide at an angle just short of 100% of the time. Getting an actual, straight, head-on collision is a very difficult task that requires a great deal of setup and effort on the part of the people doing the testing. In the real world, drivers don't arrange their crashes with such mathematical precision. "at an angle" is pretty much a given...
"Convictions are more dangerous enemies of truth than lies."
Mainly because they don't look as nice.
That said, a car accident has a massive amount of energy involved even at low speeds. That energy has to go somewhere. In a new car the energy goes into destroying the vehicle or parts of it. In an old car the energy goes into throwing the driver around. Essentially, at some people people decided that losing a car is preferably to losing their life or suffering life long disability.
The straight 6 engines in those cars offered no protection in an offset crash, and just smashed back through the dash killing the occupants, who were dead anyway.
Fucking classic-car-driving zombies...
I'm an orthopaedic surgeon, and wind up taking care of a lot of people from car accidents. Even a 10 MPH crash is enough to cause whiplash.
Car repairs are much, much cheaper than hospital bills, and there are some things that we aren't still good at fixing like cartilage damage, and whiplash - who likes chronic pain?
..........FULL STOP.
Your physics makes no sense. Why is this modded informative? The ground is not a magical reference point!
If two cars travelling in opposite directions at 40 MPH slam into each other, that's exactly equivalent, in terms of energy dissipation and momentum transfer, to one car travelling at 80MPH slamming into a stationary vehicle. Each vehicle, in its own reference frame, sees another vehicle travelling at 80MPH.
Think about it: if two identical cars crash, and one is stationary, then for a moment (before they come to a stop due to friction against the pavement) they'll be moving together at half the speed of the moving car before the crash. One car goes from 80MPH to 40MPH (40MPH difference); the other goes from 0MPH to 40MPH (40MPH difference).
This is exactly equivalent to going from 40MPH to 0MPH (40MPH difference).
When you're working out simple kinematics like this you should be starting with momentum, which is linear with velocity. You can work out how much energy is released afterwards; you'll see that it works out:
(1/2) * (1500kg) * (36m/s) ^ 2 = 972 kJ - Amount of kinetic energy in the moving car at 80MPH
(1/2) * (1500kg) * (18m/s) ^ 2 * 2 = 486 kJ - Amount of kinetic energy left after the crash: 2 cars at 40MPH
972 kJ - 486 kJ = 486 kJ - Amount of kinetic energy dissipated in the crash
(1/2) * (1500kg) * (18m/s) ^ 2 * 2 = 486 kJ - Amount of kinetic energy in 2 cars at 40MPH
(1/2) * (1500kg) * (0m/s) ^ 2 * 2 = 0 kJ - Amount of kinetic energy left after the crash: in 2 cars at 0MPH
486 kJ - 0 kJ = 486 kJ - Amount of kinetic energy dissipated in the crash
(Yes, kinetic energy is 1/2 mv^2, not mv^2!)
