Adjustments to DRS slot gaps in 2025 are redefining how Formula 1 teams approach race strategy and car design. These changes significantly impact aerodynamics, allowing for better overtaking opportunities and enhanced performance on track.

As teams adapt to these new regulations, fans can expect to see thrilling races driven by innovation and precision.

Mercedes-AMG W15 Rear Wing

The Mercedes-AMG W15 rear wing has drawn attention in 2025 for its impressive flexibility. In the following tweet, it shows significant flexing under load, especially along the trailing edge:

The tweet also noted that despite running a smaller flap angle than rivals, the W15’s wing flexes more than those on McLaren, Red Bull, or Ferrari. This flex may reduce drag and boost top speed during qualifying.

Observers speculate this design helps Mercedes top speed charts. It reflects how subtle aero tweaks drive performance gains.

Red Bull Racing RB21 DRS System

The Red Bull Racing RB21’s DRS system is designed for straight-line speed and aerodynamic efficiency. It features a refined rear wing with an optimized slot gap that reduces drag while maintaining downforce.

A CFD simulation by Luke Morgan shows how DRS alters airflow to boost top speed—mirroring the RB21’s setup. The system activates smoothly and adapts well to different circuits:

In 2025, such precision makes Red Bull’s DRS a key asset for overtaking and qualifying performance.

McLaren MCL60B DRS Package

The McLaren MCL60B features an advanced DRS package aimed at improving straight-line speed and cornering balance. It uses an adjustable slot gap and lightweight materials to fine-tune aerodynamic response.

The following video offers a clear breakdown of this unique rear wing approach:

It shows how McLaren uses airflow tricks to reduce drag without compromising downforce.

Such innovations keep the MCL60B competitive, especially on tracks where efficient DRS use is key.
