George Russell’s retirement during the Belgian Grand Prix has created a unique opportunity to analyze the secrets of Mercedes’ Formula 1 car, which currently leads the championship. The moment his vehicle was lifted by a crane allowed for the observation of cryptic details about its design, especially its platform.
F1 teams typically keep the specifications of their platform designs secret, as this part of the car generates most of the downforce. However, an accident can uncover these details that usually remain hidden both on the track and in the garage.
Sergio Pérez’s fall in Monaco in 2023 was a paradigmatic example, as it allowed other teams to analyze the efficiency of his RB19 from underneath, meaning they will better understand its performance on the track.
Currently, although the importance of platform design is not as critical as before, the view of the underside of Russell’s car at Spa-Francorchamps has revealed key aspects of the construction of the platforms of vehicles competing at the top of the grid.
Details of the Mercedes Platform
Analyzing further, this year’s Mercedes platform presents several interesting characteristics:
- Diffuser: responsible for expanding the airflow, creates a low-pressure zone behind the car, which is absorbed to generate downforce.
- Diffuser release line: indicates where the platform no longer needs to be flat.
- Wear plate: made of resin, limits how high the car can run. If it erodes more than 1 mm during the race, it is considered grounds for disqualification.
- Outer edge of the platform: establishes a size above the main body to limit downforce.
- Outer components of the diffuser: connect aerodynamics with the wheel axles and the diffuser.
- Strake diffuser: to help condition airflow under the car.
- Hole in the diffuser: an innovation to increase diffuser efficiency this year.
Additionally, other design details have been detected, such as the small droplets on the upper edge of the diffuser. Mercedes had used larger variants to increase the working volume, but had to reduce them as a result of FIA regulations.
The suspension components and rear wing have been designed to expand the low-pressure zone created by the diffuser, all interconnected to produce a high and uniform downforce at the rear of the car.
With the length of the body of the platform, one of the main challenges is to avoid airflow separation. Keeping the air moving and accelerated under the car is essential to prevent energy loss caused by surface friction.
The grooves at the corners of the platform, located in front of the rear tires, have also been adjusted to better control the tire ‘squeeze’, which can interfere with turbulent flow and affect the diffuser.
These aspects underscore that, despite a simpler set of rules than previous ones, the complexity of the platform remains crucial for the stability of the rear axle, which affects the driver’s confidence when accelerating safely.
