What you're looking at is a carbon fibre drive shaft and a steel drive shaft being twisted with force until they break. As you can see in this torque test between the two, the carbon fibre shaft doesn't budge (that's not a still image, folks) while the steel shaft corkscrews itself and becomes deformed under the same amount of twisting pressure. Gnarly.
The steel shaft gave out at around 1376Nm while the carbon fibre shaft held until 4728Nm. That's a huge chunk of difference. Strands of expensive fibre dominates metal more than three times over. Cool
