Cape Town - Eagle-eyed viewers have spotted Lewis Hamilton's steering wheel moving forward and back during Thursday's testing at the Circuit de Catalunya in Barcelona.
Hamilton, who set the early pace on the first day of testing, hopped back into the Mercedes W11 for the morning session of day two and his on-board footage has caused many to speculate over what is exactly going on with his steering wheel.
Not only is the steering wheel being pushed and pulled as Hamilton navigates the corners and straights, but those movements also seem to be perfectly aligned to the movement of the front wheels.
The leading suggestion is Hamilton is able to increase his input into the steering wheel to create dynamic ride height adjustment as he makes his way through the circuit.
Hamilton could be seen employing the mode when exiting the pit lane, hitting a button which brought up ‘marker’ on his dashboard before heading down to Turn 1.
