Mercedes has disclosed the complete list of upgrades it will bring to the Spanish Grand Prix at the Circuit de Barcelona‑Catalunya. The German team aims to close the performance gap that has persisted since the start of the 2024 season, focusing on increased down‑force, reduced drag, and a more predictable tyre‑temperature window.
Key aerodynamic changes
- Front wing assembly: A new three‑element front wing with a revised end‑plate geometry designed to generate additional front‑end down‑force without compromising straight‑line speed.
- Rear diffuser and brake duct: Updated diffuser vanes and a slimmer brake‑duct profile to improve airflow to the rear tyre, aiding stability through the high‑speed corners of Turn 3 and Turn 9.
- Side‑pod inlet redesign: A narrower inlet shape that reduces turbulent airflow around the side‑pods, feeding cleaner air to the power unit and rear‑wing end plates.
These aerodynamic tweaks are complemented by a suite of power‑unit refinements. Mercedes has introduced a revised turbocharger map and a new software calibration aimed at delivering a broader torque band, which should help drivers maintain optimal tyre temperatures on the abrasive Barcelona surface.
Strategic intent
Team principal Toto Wolff emphasized that the upgrades are part of a “continuous development philosophy” intended to extract maximum performance from the W15 chassis. "We have identified specific areas where we can gain a few tenths of a second per lap, and the Spanish circuit is an ideal test‑bed for those concepts," Wolff said in a post‑release briefing.
Drivers Lewis Hamilton and George Russell will have the opportunity to evaluate the upgrades during the free‑practice sessions on Friday. Both drivers have highlighted the need for a more stable rear‑end feel, especially under heavy braking into Turn 1, a concern that the new rear‑wing and diffuser package directly addresses.
For Indian fans
