That said, FormulaUno.it reports that Mercedes has arrived with much more than a routine upgrade package for the W17. Almost the entire aerodynamic concept has been completely redrawn, leaving the wings as virtually the only major elements from the previous specification.
The most striking visual transformation hits the sidepods. The Brackley aerodynamicists have pivoted heavily toward a downwash philosophy, bringing their machine remarkably close to the route taken by McLaren. It makes for a fascinating technical paradox, especially given that McLaren actually moved in the opposite direction at Baku by drifting closer to older Mercedes ideas.
As it turns out, the timeline explains the twist. Mercedes locked this design into the wind tunnel back in June, extracting solid gains in cornering load that justified rebuilding the central and lower sections of the car. The lower side channel of the previous setup is gone, replaced by a smooth slope that integrates cleanly with the floor, eliminating the old 'double floor' entirely and narrowing the Coca-Cola region.
Naturally, you cannot reshape the bodywork so radically without touching what lives underneath. The floor, floor fences, and floor board are all brand new, alongside a redesigned engine cover built to handle the altered airflow heading toward the rear. Apart from the wings, it is genuinely difficult to spot an aero section on the W17 that has escaped this massive overhaul, though further wing updates are already slated for upcoming rounds.
The driving force behind this massive effort was simple: extra downforce in the corners, specifically targeting medium-to-high speed turns where the tunnel data showed a very significant payoff.
Now, here is the challenge. Rebuilding the entire aerodynamic platform outside of the wings is one thing, but extracting its potential immediately is another beast entirely. Mercedes must now prove that the wind tunnel numbers from June translate cleanly to the track while rapidly figuring out the ideal ride heights, balance, and setup window for a heavily altered machine.
