Okay boys,
Lets try and get back to the topic please... Quote:

But the fact remains that the gauge of the Maruti metal is their weak link in comparison to the other manufacturers. From the pic you can see at max 250 kgs of weight would have piled on the roof that too not instantaneously.
Therefore roof need not have really dented. |
emkay,
Im pretty sure that if you get 4 grown men to celebrate on the roof of any car, there will be dents.
However, im not doubting that some cars dent easier than others, but then again (as below) thats what keeps FE high and manufacturing costs low, which is probably why you like your swift too...right?

3. Lesser weight means less wear and tear of movable parts (Tyre, brakes etc.)
4. Lesser weight gives lesser braking distance for the same speed.
5. Lesser weight means lesser money to produce cars.
Yes thin sheet metal bodied cars have disadvantage of being fragile but advantages IMO more than outweigh this disadvantage. |
Well said DieselFan,
To add another point, the stronger/thicker (~=heavier) the metal is on the roof, will raise the CG of the car and make more bodyroll and pitching happen.
Also, in terms of rollovers its the pillars that must be taking most of the load, and hence the thickness of the roof doesnt really matter too much.
