The current US impact standard calls for bumpers to be tested at TWO-AND-A-HALF miles per hour, not SIX. Why would these crooks test bumpers at a speed they were never meant to absorb? Even the original 1973 standard (lobbied for by the same insurance institute that's complaining now) never went above FIVE mph. Notice they never said what "standard" the bumpers were made to? They simply quote the automakers defensively saying that their bumpers "meet the standard" without saying what the "standard" was. The Escort in question had plain-steel 5mph bumpers. $86? I wonder about that. Did they source the hydraulic cylinders from a wreckers and not count labor costs? Did they just live with a bent bumper bar? They don't say. In any modern bumper, most of the repair cost for the actual bumper would have been in replacing and painting the bumper skin covering the rebar. And did you notice the Escort didn't submarine under the impact bar? Most all the others did. Most of the expensive damage wasn't from the bumper repair, but from damage to the hood, cooling system, rad support, fenders and lighting. All resulting from underriding the beam. There are bumper-height standards the automakers have to meet. I'd like to know why the underriding. Did you know the United States and Canada are the only countries in the world with bumper impact standards? A final, hilarious irony: The video starts with an ad for the Honda CR-V, which, since it's a light truck, DOES NOT HAVE TO MEET ANY BUMPER STANDARDS AT ALL! What a joke. F-U, MSNBC. -- Tegger |

Inflation. Anyway, the difference is that instead of chrome plating the bumpers and and hanging them so they stick out inches from the body work, the bumpers are painted steel and live behind a decorative painted flexible cover that is styled into the body work of the car. Also instead of cheap sealed beams the headlamps are molded and styled into the bodywork. |

On cars of that vintage there are hydraulic cylinders that are supposed to be replaced with every bump but generally are servicable as is if the bumper is hit square. They hit the bumper square which is, now that I look at the video the biggest part of how the the insurance institute for higher surcharges has once again skewed a test for much more dramatic results and has to do with your question below. > And did you notice the Escort didn't submarine under the impact bar? > Most all the others did.

There are > bumper-height standards the automakers have to meet. I'd like to know > why the underriding. The underriding is clearly due to the location the bar being crashed into relative to modern car bumpers. The bar appears to be set at the height of the top of large 74-80something bumpers. The bar is also rather narrow in width from top to bottom. It actually looks a bit smaller than the '81 escort's. There is another thing, lots of space under the test bar, where on anything but a truck, this wouldn't be. Trouble is, todays cars don't have squared off bumpers, so what happens is that the bumper hits the bar but because of the shape of the bar and the bumper, the bar runs along the surface of the bumper cover and smashes into the head lamps as there is space under the test bar for the bumper of the car to go. All the cars would have done significantly better if they were bumped into each other instead of a test bar with geometery that favored the older style bumpers. There would not have been any under-riding. The test if anything, shows the difference when rear ending a box truck or similar large vehicle with an overhanging fixed heavy steel bumper at the high end of passenger car bumper height. The test was IMO designed to get the results it did. Having an '81 escort on hand to compare pretty much seals that. |

Because people do actually have accidents at higher speeds. Therefore, having bumpers tested at higher speeds, and probably designed to deal with higher speeds, is a good idea. >The Escort in question had plain-steel 5mph bumpers. $86? I wonder about >that.

But maybe they declared the Escort totalled and $86 was considered the value of the vehicle. >And did you notice the Escort didn't submarine under the impact bar? >Most all the others did.

I think that is shameful. Welcome to the SUV Revolution. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Everybody has an '81 Escort... hardly anybody has one that actually runs... --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

"Tegger" > wrote in message ... > > wrote in > And did you notice the Escort didn't submarine under the impact bar? > Most all the others did. That was exactly my take on it too, Tegger. The submarining brought the impact bar up into expensive country on the newer cars. |
