Mercedes has struggled to master the complexities of ground effect since its introduction in the 2022 regulatory changes. The Brackley-based team has secured only three race wins during this period, all of which came in the span of just four races this season. This brief surge initially sparked optimism within the team, but hopes were dashed following the summer break. Now, Mercedes’ technical department seems at a loss when it comes to effectively integrating ground effect into the design of the W15.
However, the Mercedes squad has shown signs of a comeback for the first time after the summer break. The rigorous work of a technical team led by James Allison is finally reaping results, as George Russell finished 0.012 seconds behind pole sitter Max Verstappen in sprint qualifying. Following this sudden upsurge, the technical expert explained the upgrade package and its efficacy.
A Deep Dive Into Mercedes’ Technical Overhaul For Austin GP
Mercedes has made significant strides in improving its car’s performance after facing setbacks with its floor configuration earlier in the season. The team, which had to modify its Spa floor setup repeatedly, seems to have found a more stable direction at the United States Grand Prix. The updates introduced are extensive and have been designed to work harmoniously across various car components, from the front wing to the rear.
One of the key adjustments involves a new spanwise flap distribution in the front wing, which has altered the balance between outwash and downforce generation. This is complemented by changes to the upper wishbone fairing, which has been a recurring feature during this regulatory period. Further along the car, Mercedes has adopted an overbite sidepod solution while retaining the P-shaped inlet, though it has been repositioned further back. This alteration has also led to adjustments in the bodywork around the sidepod, improving airflow performance, including around the undercut region.
In an effort to boost the floor’s performance, the team has also modified the forward fences and edge wing. Notably, the edge wing now features six strakes instead of five, with the latest addition presenting a hook-like shape to enhance airflow collection. Mercedes has also increased the car’s cooling capacity, adding outlets around the upper wishbone’s forward leg.
Andrew Shovlin Explains Mercedes Extensive Upgrade Package
Trackside engineering director Andrew Shovlin clarified that while the floor upgrade is new, it is more of an evolution of the previous floor used at Spa rather than a completely different design. He emphasized that the changes reflect a continued development process, with constant improvements being made in the wind tunnel. Shovlin noted that while the aerodynamic team is working daily to push performance boundaries, the updates introduced in Austin aim to provide a significant enough step forward to make a noticeable impact on the car’s performance on track.
