Moving images of Mercedes trick that could cost Verstappen the title

After the first free practice session of the United States Grand Prix, it has been noticed that Mercedes seems to be driving with a flexible rear suspension. It would provide an aerodynamic advantage which would mainly ensure a higher top speed of the W12. Does Mercedes have an important advantage over Red Bull Racing here?

On the straights, the rear suspension of Lewis Hamilton and Valtteri Bottas' cars seems to sag a little, lowering the rear end. The rear wing drops a considerable amount, which increases top speed. On braking for the corner the rear suspension returns to its original position.

At Sky Sports they analyse footage of the Mercedes car at Istanbul Park and it seems that Mercedes has invented a clever trick which for now still fits within the regulations of the FIA.
