Red Bull Formula 1 – Could Vettel had traction control in the past?

In the past years when Formula 1 had traction control, the engine had a slight crackling noise around a turn when traction control was in use.
This goes to question Sebastian Vettel’s dominance in the past four years. Interestingly enough, Mark Weber’s F1 car did not make the same noise. Judge for yourself. (Allegedly)

Check out the noise Sebastian Vettel’s F1 car makes when it goes around a very bump curve and compare to the other drivers on the road.

Now watch this video below and listen to the noise it makes when the F1 car traction goes off around the corner. This was when traction control was legal in F1. See the similarities?
