Wow, my glass roofed Scion TC is second in strength to weight ratio of roofs?

http://scionnews.net/2008/05/0...d-roof-crush-standard/

The current roof crush standard requires the roof to support 1.5 times the weight of the vehicle.

The National Highway Traffic Safety Administration (NHTSA) new proposed standard would require roofs to support 2.5 times the weight of the vehicle.

More?Auto safety critics say such a standard won?t do the job ? that 75 percent of automobiles currently on the road could meet the 2.5 standard.

They are calling for a standard that would require roofs to support at least four times the weight of the vehicle.

Bloch said that the vast majority of rollover fatalities and injuries are the result of the roofs crushing down on the passengers ? or when the roof crush shatters the side window glass, allowing deadly ejections to occur.

Bloch said that in addition to the almost 11,000 fatalities a year from roof crush accidents, in 2005 the total number of quadriplegic injuries in motor vehicle collisions totaled 5,608 according to the National Spinal Cord Injury Statistical Center in Birmingham, Alabama.

A significant number of those are due to roof crush in rollovers, Bloch said.

Bloch said that the auto companies know how to make safe roofs, but only eight vehicles currently on the road meet his proposed standard of a strength to weight ratio of four to one or more.

According to Bloch, those vehicles are: The 2006 Volkswagen Jetta has an SWR (5.1 to one), the 2007 Toyota Scion tC SWR (4.6 to one), the 2006 Volvo XC 90 (4.6 to one), the 2006 Honda Civic (4.5 to one), the 2007 Toyota Tacoma pickup truck (4.4 to one) the 2006 Mazda 5 (4.4 to one), the 2007 Toyota Camry (4.3 to one), and the 2007 Toyota Yaris ? it?s a small inexpensive car ? (4.0 to one).

It says 2007 Scion TC, what about the other model years?

So it can support 4600 lbs?

I saw a jeep wrangler and a scion tc head on collision in pasadena a couple years ago. The scion was unrecognizable but the guy walked away somehow.

Well the Scion TC does have a 5 star Driver's side frontal impact rating.

I figure my 07 Jetta is the same SWR as the 06? And funnily enough, I owned an 06 Civic too. lol, I can pick em good.

But it's still a Scion.

It's physics. The impact of the wreck is taken by the car so it doesn't transfer to you.

Woohooo! That means, I can strap down 50 sheets of wallboard to the roof of a geo metro Seriously though, the guys at a lumberyard once thought I was absolutely insand for putting 5 or 6 sheets of wallboard on the roof of whatever car I was driving at that time.

 

[40Hands]

At least it's not an xB. Those things are the stupidest looking cars. Right next to the VW Bugs.

A beer can has a higher weight bearing capacity to weight ratio than a modern steel building. Does that mean you're going to build a house from beer cans. Ratio specs must be taken with a grain of salt.

And yes, I'm comparing your car to a beer can

 

[Yanagi]

Probably not so much due to roof strength but rather to wind resistance

It's not how many pounds can it hold, it's "can it hold the weight of the car if it's upside down, or flipping over multiple times?" I'm sure the roof of a hummer can hold far more than the roof of a geo metro. However, the geo metro doesn't need to hold more; it simply has to support a safe amount of force which is related to its own weight.

I knew it'd be that photo. Of course, not me. I would read the sticker on the door or in the glove box listing the maximum gross weight. Then, I'd guess at how much of an extra safety factor was built in. For the grand caravan, I just remember the commercials with a bunch of big football players in one. If it can carry 6 NFL linemen, I can safely put 1200 pounds of cargo in it

How do we know if it is the glass roof they tested or just the regular hardtop?

What do you drive? A Ssangyong?

I have never heard of a hardtop Scion TC, please correct me if I am wrong.

The manual is lighter than the automatic so the average weight of the 2 models is 2,937 lbs.

2937lbs x 4.6 = 13,510 lbs.

13,510 lbs is impressive for any roof, let alone a glass one although it would be a few lbs less if they tested the 5 speed version.

Purchased new in 2004 for $15,945 for a fully loaded hatchback coupe, 0-60 times of just over 7 seconds. Four years later the resale value is 85%-95% of the purchase price, rated at 27 highway MPG but got 34 MPG going 70-75mph driving from Virginia to California fully loaded down with my stuff. I am probably going to sell the car later this year for only a few thousand less then what I paid for it brand new 4 years ago. Those things considered, I don't really mind the fact that it is Toyota Scion.

The center section of the roof has next to no impact on the load-bearing capacity. The pillars are what carry the weight. The fact that the tC has a very large sunroof has no real effect on the overall load bearing capacity since the flat part of the roof is not responsible for support. I could take a Sawz-All and cut a giant hole in the roof of almost any steel-roofed car and as long as the edges (where the support structure is) were left intact the ability of the roof to support an even load would not diminish.

Also worth noting is that the glass, like any other sunroof, will almost certainly shatter in a rollover accident.

i'm in trouble now, i don't have a roof (roadster!)

 

[senseamp]

That is one reason I didn't buy a tC. A pillar is too thick, didn't like the visibility.
