Pink Bull outlines an enormous vary of modifications to its automobile for 2025, with the entrance wing, nostril, entrance suspension, ground, sidepods, cooling louvres, rear suspension, beam wing, rear wing and rear wing endplate all up to date. It’s the ground that continues to be an enormous efficiency differentiator, and on this space Pink Bull says a “revised form improves stress distribution given different modifications to the ground to extract extra load and preserve circulation stability”.
At Mercedes, a change to the low rear observe rod delivers improved airflow to the ground, the place up to date ground tunnel profiles enhance load and circulation high quality to the diffuser. There’s additionally modifications to the sidepod – together with an elevated undercut – and new beam wing and rear wings that Mercedes says is extra environment friendly.
