Mercedes has introduced a significant upgrade package to its W17 car ahead of the 2026 Bahrain Grand Prix in Malaysia, focusing on a redesigned floor and new sidepods. These changes aim to enhance the car’s aerodynamic performance, particularly by improving airflow and increasing rear downforce, as the team seeks to maintain its competitive edge in the championship.
The updates to the floor include modifications to the floor board, leading edge, rear corner, main underbody, and diffuser area. The sidepods have shifted from an undercut geometry to a ramped profile, a design intended to better manage airflow around the car and increase pressure differential near the diffuser. Additionally, rear suspension fairings and winglets inside the rear wheel drums have been revised to complement these aerodynamic changes.
Mercedes delayed early-season upgrades to concentrate on winter development, resulting in fewer parts introduced during the first races of 2026. This package marks the team’s first major upgrade since the Canadian Grand Prix in May. George Russell, who recently secured a victory in Baku, described the upgrade as an important step toward regaining performance on circuits where the team has faced challenges.
The floor’s reworked upper slat now features a lower leading edge and two vertical elements behind it, designed to better control airflow disturbed by the front tyre wake. The new sidepod design is intended to improve the pressure differential around the diffuser, which should contribute to increased downforce at the rear of the car. These aerodynamic refinements are part of Mercedes’ ongoing efforts to optimize the W17’s balance and efficiency.
While the W17 has demonstrated strong pace in the early part of the 2026 season, it has encountered intermittent competition from Ferrari, McLaren, and Red Bull. The upgrades aim to address some of the performance gaps experienced on certain circuits. The team will also run a special teal and black livery in Malaysia to pay tribute to its title partner Petronas, Malaysia’s national oil company.
Russell’s comments suggest the team views this package as a meaningful development rather than a guaranteed solution to all performance issues. The changes reflect Mercedes’ strategic approach to development, prioritizing comprehensive updates over incremental parts throughout the season. This upgrade is expected to provide a platform for improved competitiveness as the season progresses.
Overall, Mercedes’ floor and sidepod updates for the Bahrain Grand Prix represent a technical evolution aimed at refining aerodynamic efficiency and rear downforce. The team’s approach underscores the importance of targeted development in maintaining performance levels amid strong competition in the Formula 1® championship.
