During recent pre-season testing, Mercedes and Ferrari showcased their engineering prowess by experimenting with serrated edges on their rear wings, a design element aimed at enhancing aerodynamic performance.
"Engineering a Formula One car, especially in an era of rule stability, is all about finding marginal gains," said a source close to the teams. This sentiment captures the competitive spirit as teams seek every advantage available.
Mercedes began its experiments with serrated edges late last season. At the Suzuka circuit, the Silver Arrows introduced serrations to their front wing flap, laying the groundwork for their ongoing aerodynamic refinements. Notably, they also tested a serrated pattern on the trailing edge of the rear wing main plane, which proved to be a focal point during the pre-season testing in Barcelona. On the final day of testing, a new rear wing main plane and top flap were introduced—much akin to the designs pioneered by McLaren in 2014.

The motivation behind the introduction of serrated designs is clear. "The thinking behind this design is to improve efficiency by reducing airflow separation and to allow airflow to reattach more easily once the DRS wing flap has reverted back to the standard position," a technical analyst explained.
In parallel, Ferrari pursued a similar path, echoing the design philosophy of past competitors. Their experimentation with serrated edges recalled the efforts made by Williams over a decade ago, specifically employing a serrated Gurney flap on the trailing edge of the top flap. "This solution helps to create mini vortexes which should reduce drag and increase efficiency," explained a Ferrari engineer. However, the Scuderia only retained this design on the SF16-H during the first morning of the second test, raising questions about its future implementation.
Fans and experts alike are left pondering whether Ferrari will integrate this innovation into their race weekend strategy in the upcoming season. "Will they use it at a race weekend in 2016? Watch this space…" noted a Formula 1 analyst, hinting at the unpredictability of team strategies in a highly competitive environment.
With both Mercedes and Ferrari pushing the boundaries of design in pursuit of performance, the upcoming season promises to showcase thrilling developments in F1 technology. As teams finalize their plans for the season, the significance of these aerodynamic advancements cannot be overstated, hinting at a battle for supremacy both on and off the track.
