Mercedes have clearly been strong in the last four years relying heavily on their powerful engine.
But this year, they’ve made small aerodynamic changes in the bid to keep them above title rivals Red Bull and Ferrari.
Craig Scarborough, talking to motorsport tv’s weekly show, has discussed these changes: “At the very end of the first test, they had a small aero update - this consisted of a number of bits and pieces.
“The key thing is it had a slightly different front wing and it’s all the outboard section that goes out towards the wheels.
“As the endplate flicks out it used to have a couple of twisted vanes: they’ve been cut out completely and there’s a big vane there that pushes the air towards the tyre.
“The other change they’ve made is to the cape (tuning vanes underneath the nose cone).
“Before it had a horizontal leading edge. Now it kind of droops down a bit to push more air under the cape to get this bigger vortex effect out the back that goes through the bargeboards.
“They’ve got a few other slots and bits and pieces as well so you can see they are pushing that concept a little bit further every time.”
In the past, the silver arrows car has come under scrutiny when running behind cars in the dirty air. Perhaps this could be the problem solver?
