Mercedes Introduces Major W17 Upgrade Package at Sepang

Entering the 15th round of the season at the Sepang International Circuit, Mercedes has introduced an aggressive W17 upgrade package aimed at increasing overall downforce without incurring drag penalties. The Brackley-based team focused its alterations on the rear of the car, featuring an upward ramp to condition airflow towards the rear axle, reprofiled suspension fairings, and repositioned rear-drum winglets. Additionally, Mercedes brought a substantially reworked floor featuring a completely redesigned floor board, edge, corner, and body to increase local load and improve robustness.

Among other top teams, McLaren introduced a circuit-specific engine cover designed to handle cooling under Malaysia's sweltering climate. Red Bull fitted a tweaked version of its existing floor, specifically modifying the outer extremities at the front to enhance airflow stability behind the front tyres. Meanwhile, Ferrari brought a single upgrade to its SF-26, altering the diffuser to gain additional downforce across its operating window.

In the midfield, only three teams opted for package alterations at Sepang. Racing Bulls brought revisions to its front and rear wings, while Alpine made minor changes around the front brake drum corner for cooling purposes. Haas brought a standby upgrade package featuring a revised rear impact structure available on track for targeted tuning.

In contrast, Williams, Aston Martin, Audi, and Cadillac did not bring any upgrades for this race weekend.
