Analysis: Can an aerodynamic overhaul make Mercedes’ W16 a regular winner?

The shifting goalposts, on the subject of allegories and idioms about luck, sidestep from “third time’s the appeal” to “unhealthy luck is available in threes”. And, on the subject of Method 1’s present technical laws, Mercedes’ personal expectations could make an analogous step as its third automotive on this ruleset – the W15 – couldn’t convey an finish to the difficulties it has confronted with constructing a constant race winner.

Certain, it gained probably the most races of any automotive it has produced since 2022, however the staff was additionally a distant fourth behind McLaren, Ferrari, and Pink Bull within the constructors’ championship. This reasonably lays the inconsistency of the W15 naked, because the automotive usually struggled to stroll a high-wire act between holding its Pirelli tyres of their temperature window and overheating them to some extent the place the automotive hardly ever felt malleable for both George Russell or Lewis Hamilton. In cooler circumstances with smoother monitor surfaces, this flaw was hardly ever a problem, however these stars had not aligned on the majority of 2024’s races…

Can the W16 repair these points, and permit Mercedes to log out from the present era of automotive on a excessive? To do this, the staff must have understood final yr’s points – and the problems skilled within the earlier two seasons – and stroll the road traced out by all of its earlier misgivings by strategy of elimination.

Visually, there are myriad key variations in comparison with the W15 – which, in flip, was very totally different to the W14. It seems like Mercedes has coated each single risk with its aero work over the previous three years, and the automotive is now set off by a drooped, chiselled nostril that extends additional ahead than its predecessor. The tip now sits midway alongside the entrance wing mainplane, which is spoon formed within the centre.

Lots of the entrance wing’s mod-cons are evolutions of ideas that the staff explored final yr; the distribution of the 4 wing parts incorporates a comparatively short-chord mainplane and a long-chord second aspect, one which extrudes forwards on the junction with the endplate. The third and fourth parts are brief in chord and have the sequence of tiny particulars at their attachment level to the endplate seen final yr; these hyperlink to an extra plate with tiny fins that duct airflow outwards by the hole within the endplate and across the entrance tyre to mitigate the impact of wake turbulence on the ground.

The staff has caught with a push-rod entrance suspension association, deciding to not be part of its fellow front-running hopefuls with the swap to a pull-rod and profit from the decrease rocker place. Regardless, it has revised the place of its entrance suspension members, though it seems to be with out the ‘adjustable’ higher wishbone the place the staff ran with a removable panel that might place the rear leg at two totally different positions alongside the chassis flank.

Maybe the largest seen change to the formulation comes with Mercedes’ adoption of Pink Bull RB20-esque sidepods that characteristic a totally built-in inlet overwing and break up inlets; one recessed into the undercut and the opposite alongside the chassis bulkhead. This has allowed the staff to pursue a big undercut alongside the sidepods, one with a bulge beneath that ought to mitigate any potential era of raise on this space and in addition permit area for the radiators to take a seat.

It seems as if the staff is holding its playing cards near its chest with its ground, choosing one which ran in an analogous specification (alongside the sides, at the very least) on the finish of final season. There’s additionally a quasi-return of the high-sided engine cowl, albeit not as excessive because the one run in 2023, because it has been moulded to shrink the bodywork across the rear suspension – which retains a push-rod structure.

Making the W16 a way more predictable buyer, with out the expense of dropping any velocity, would be the key between providing a real problem for race wins and sinking additional behind

Like Ferrari and Haas, Mercedes has swept the mountings of its higher wing airplane additional ahead, which permits the mainplane to be partially reduce away on the level at which it meets the endplate. This enables the aerodynamicists to play with vorticity right here, giving the automotive the possibility to generate airflow patterns that not solely increase the effectiveness of the rear wing however permit it to hyperlink with the beam wing and the circulate from the underbody.

Making the W16 a way more predictable buyer, with out the expense of dropping any velocity, would be the key between providing a real problem for race wins and sinking additional behind final yr’s Huge Three. The adjustments to the aerodynamics of the automotive have been all-encompassing, with additional modifications below the pores and skin to make sure that the automotive lastly delivers on Mercedes’ aspirations to get again into extra common podium finishes.

With a rookie driver on board in Andrea Kimi Antonelli, the necessity for predictability is magnified. Thought-about to be a precocious-yet-raw expertise, the Italian wants one thing he can depend on to make sure he can get a correct grounding in F1; a yr with final yr’s automotive would probably hamper his studying expertise behind the wheel. It’s going to be as much as Russell to guide the event from the cockpit, and he’ll be a demanding affect on the staff; if he would not assume the brand new automotive is as much as scratch, he’ll say it. With out Hamilton’s aura, Mercedes may very well be forgiven for lacking one thing; Russell should fill that void.
