What you're looking at is a carbon fiber 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 fiber shaft doesn't budge (that's not a still image, folks) while the steel shaft cork screws itself and becomes deformed under the same amount of twisting pressure. Gnarly.
The steel shaft gave out at around 1376 newton meters while the carbon fiber shaft held until 4728 newton meters. That's a huge chunk of difference. Strands of expensive fiber dominates metal more than three times over. Cool
