Most Formula 1 teams have incorporated design elements seen on Red Bull cars in recent years, but Mercedes continues to follow its own path. The latest Mercedes challenger, the W15, showcases unique design choices, indicating the team’s independent approach.
While Mercedes has observed trends from the past two seasons, it has not blindly replicated designs like the inlet design from Red Bull’s RB19,
as many others have. Instead, Mercedes has adopted a distinct strategy, likely influenced by lessons learned from the B-Spec configuration of the W14.
One noticeable change from last season’s design is the absence of the upper side-impact spar (SIS) fairing, which previously served its own aerodynamic purpose ahead of the sidepod and inlet.
This adjustment has also led to a repositioning of the cockpit, which now sits farther back by about 100mm, resulting in changes to the chassis and fuel tank.

Additionally, Mercedes has introduced a P-shaped sidepod inlet, allowing air to flow efficiently to the rear of the car. The downsloping sidepod bodywork retains a gentle waterslide solution introduced in 2023 but with modifications.
At the rear, Mercedes has switched from pull-rod to push-rod rear suspension, necessitating a comprehensive overhaul of the mechanical and aerodynamic packaging.
The front wing features a novel flap design, and the front suspension layout has been optimized for the new aerodynamic setup.
Furthermore, Mercedes has refined the airflow passage through the upper wishbone region and abandoned the chassis blister arrangement used in previous models.
Changes have also been made to the rear wing tip section, aligning with solutions introduced by other teams during the previous season.
