That's not even that impressive and pretty standard for the industry. The relatively pedestrian Mazda3 resists 18,239lbs, which is 6x it's weight.

Just about every family sedan on the market does >5x body weight.

Is the Mazda3 roof made out of glass?

It doesn't matter because the glass isn't load bearing. Sunroofs are even less rigid and safe than panoramic glass roofs and cars have been passing safety tests with those for decades.

What's being measured is the strength of the bars that make up the roof, not the glass.
