Mazda doing well in low speed crashes

http://www.cnn.com/2009/US/08/06/car...udy/index.html

Go Mazda!

I'd agree with the findings that it is pretty unacceptable. Maybe my memory is just horrible, but I thought bumpers were supposed to be designed to result in zero damage to the car (or bumper) in impacts up to 5mph. Maybe it was 3mph. I know even 5mph is a lot of crash energy when your talking about a ton and a half...but seriously? You can't design a bumper and shock absorber from the front and rear that can take a 5mph impact with little or no damage other then maybe some scratching? I'm not looking for a 30mph impact without a scratch, but as the article point out, a small bump.

Re: Mazda doing well in low speed crashes

i can attest to these findings. when i got rear ended while sitting at a light there was not much damage. the other persons car didn't even have a scratch. all i had was a broken reflector and some denting around that area. the foam absorber did it's job definitely. to fix it all i did was replace the reflector and straighten out the bumper cover.

Re: Mazda doing well in low speed crashes

Yeah, smaller cars seem to actually do better then larger cars in low speed crashes. Probably because they have a lot less mass to move/stop.

Re: Mazda doing well in low speed crashes

I got rear ended at a fairly low speed, probably around 10 mph. It was about a grand for a new bumper cover. There's just not much you can do to keep plastic from cracking when it's compressed. Unless they start making our bumpers out of silicone.

Re: Mazda doing well in low speed crashes

I got rear ended pretty good a couple years ago, I had some scratches, a small dent in the license plate, and one part of the plastic was cut. Very very minor. Speed I couldnt say exactly, but I was going 80 km/h, and the light turned, I was close enough to slow down safely, and braked (not gonna lie it was a little hard for comfort). The guy behind me braked as well, but was too close and rear ended me. When I was nearly at a stopped speed he pushed me past the white line, part way into the intersection.

I found it interesting how the 6 received the highest and the Fusion received the lowest. Same car but not.

Re: Mazda doing well in low speed crashes

The design of the car and bumper attachment has a lot to do with how well the bumper does its job.

Years ago, when a bumper was not directly attached to the body (It was attached by means of several springs) the bumper and the springs (and in worst cases the mounting points) would be the things mainly absorbing the crash energy.

Now with the bumpers molded into the body and the rules no longer stating that the surrounding hardware must also take the crash forces unscathed (Even in Canada, where the bumper standard is still 5mph / 8km/h there are no requirements regarding the surrounding hardware) any collision, no matter how small, can result in thousands of dollars in damage as manufacturers seek to lighten cars and better fuel economy with the increased use of plastics in bumpers.

Why the auto insurance industry never fought against this, I'll never know since these things come out of their pockets.

Re: Mazda doing well in low speed crashes

It's okay...my wife was backing up and hit the edge of the mower, scratched the lower front portion of the bumper!
She can't back up STRAIGHT out of the garage, always has to turn the wheel. I'm in the pass. seat and all of the sudden, I hear a "boom" and see the mower go up a few inches and then down. Of course, it was my fault for having the mower right there, where it's against the wall and clear the car doors.
Well, I found some of the 04-06 wagon front lip pieces for a pretty good deal, I think those will cover up the nice scratches and small gash.
The old 1988 5 HP Craftsman is just fine, of course, but I might take off the side discharge (no bagging) so it doesn't happen again.
