Ferrari Leads the Charge with Significant Floor Update
Among the front-runners, Ferrari made headlines by introducing a substantial upgrade package, centered around a redesigned floor for their SF-23 challenger. The Italian Scuderia described this as a key part of their “standard development cycle,” signaling their ongoing commitment to extracting maximum potential from their car throughout the season. The floor, often considered the most crucial aerodynamic component in modern ground-effect Formula 1 cars, plays a pivotal role in generating downforce. Even minor alterations can have profound effects on a car’s overall performance, stability, and efficiency.
Ferrari’s technical documentation submitted to the FIA detailed that “particular attention has been put on losses-reduction in all the updated areas,” with the explicit goal to “improve the overall aerodynamic performance and car efficiency.” In Formula 1 aerodynamics, ‘losses’ refer to any undesirable turbulence or energy dissipation in the airflow, which reduces the car’s ability to generate optimal downforce and minimize drag. By minimizing these losses, Ferrari aims to create a cleaner, more efficient aerodynamic package, which should translate into better cornering speeds and improved straight-line performance on the challenging Miami circuit. This continuous refinement is vital for Ferrari as they battle for supremacy at the top of the constructors’ standings.
Aston Martin Prioritizes Cooling, While AlphaTauri Focuses on Balance
Another team making strategic changes was Aston Martin, who brought an extra cooling option for their AMR23. The decision underscores the harsh environmental conditions often encountered at the Miami International Autodrome. Last year’s race was notably one of the hottest of the season, with ambient temperatures soaring to 30 degrees Celsius. Such extreme heat can severely impact engine reliability, power output, and even driver comfort and performance. By offering an additional cooling option, Aston Martin aims to ensure their power unit and other critical components operate within optimal temperature ranges, allowing the car to maintain peak performance throughout the demanding race distance, regardless of the conditions. This adaptability is key for a team looking to consistently challenge at the sharp end of the grid.
AlphaTauri, a team that had been diligently working to enhance its car’s low-speed balance, introduced a pair of revisions to its AT04. The first was a new front wing, a crucial component that dictates how airflow is managed over the entire car, especially influencing the performance of the all-important floor. A well-designed front wing can optimize the airflow to the underbody, thereby maximizing the ground effect and the downforce generated by the floor. Their second update involved a new winglet integrated into the rearview mirrors, meticulously designed to refine the airflow around these seemingly small but aerodynamically significant elements. Even minor disruptions caused by mirrors can create turbulence, negatively impacting the efficiency of other aerodynamic surfaces further downstream. By optimizing airflow around the mirrors, AlphaTauri seeks to ensure a cleaner, more stable flow field across the car, contributing to improved overall aerodynamic efficiency and stability, particularly in slower corners where balance is critical.
Haas and Alfa Romeo Seek Aerodynamic Gains and Setup Flexibility
Haas, leveraging its close technical partnership with Ferrari, also arrived in Miami with a new floor design for its VF-23. Like Ferrari’s update, Haas’s new floor is strategically intended to improve the car’s overall aerodynamic efficiency. For a team like Haas, operating with a smaller budget compared to the sport’s giants, every aerodynamic gain is immensely valuable. Enhancing the floor’s efficiency can unlock significant performance across various speed ranges, making the car more competitive in both high-speed sections and tighter turns. This continuous development effort is crucial for Haas to climb up the constructors’ standings and consistently challenge for points.
Alfa Romeo, meanwhile, adopted a different approach. They brought a previously-used beam wing, but with the intention of deploying it in a novel configuration for the Miami Grand Prix. The beam wing is a small, often overlooked, aerodynamic element located at the very rear of the car, underneath the main rear wing. It contributes to downforce generation and influences the airflow around the diffuser. By offering a different configuration option, Alfa Romeo gains greater flexibility in managing the drag-downforce trade-off, allowing them to fine-tune the car’s setup to better suit Miami’s unique track layout. This adaptability is vital for extracting optimal performance from the car across a circuit that demands both high straight-line speed and strong cornering grip.

- Description: “This is an additional configuration of previously utilised parts; we have added this possible combination to give us an additional aerodynamic solution to respond to the characteristics of the Miami track.”
Elaboration: Alfa Romeo’s beam wing update provides crucial setup flexibility. The beam wing, located beneath the main rear wing, significantly influences the car’s overall downforce and drag levels. By introducing the option to run the beam wing without its flap, Alfa Romeo can fine-tune the car’s aerodynamic balance more precisely. This is particularly valuable for a circuit like Miami, which features a demanding mix of long, high-speed straights where drag reduction is paramount, and technical, medium-to-low-speed corners where maximum downforce is needed. This configurable element allows the team to optimize for specific track characteristics, potentially finding a sweet spot between outright speed and cornering grip that was previously unavailable.
Aston Martin
Cooling Louvres
- Reason for change: Circuit specific – cooling range
- Difference: “A new bodywork panel is available for R05 with an additional area of cooling exits in the side of the bodywork. Use will be dependent on the conditions.”
- Description: “The additional exit area allows more cooling flow to exit from the underbody cavity hence increasing cooling capacity allowing operating targets to be met in hotter conditions.”
Elaboration: Aston Martin’s new cooling louvres are a direct response to the anticipated high temperatures at the Miami Grand Prix. The additional exit area in the side bodywork allows a greater volume of hot air to escape from the car’s underbody cavity, significantly enhancing its cooling capacity. In Formula 1, effective cooling is vital for maintaining engine performance, preventing overheating of vital components, and ensuring driver comfort. By increasing the car’s ability to shed heat, Aston Martin can ensure their power unit operates at optimal temperatures throughout the race, preventing performance degradation and ensuring reliability, particularly if the Miami heat is as intense as predicted.

Haas
Floor Body
- Reason for change: Performance – local load
- Difference: “Geometry of the surface that control the expansion of the floor has been modified.”
- Description: “With a better control of the pressure distribution and the management of the lateral flow, we have obtained improvement of the car aerodynamic efficiency at low, medium and high speed.”
Elaboration: Haas’s floor body update focuses on refining the geometries that control the expansion of the floor. This aspect is crucial for managing the intricate airflow underneath the car, which in turn dictates pressure distribution. By gaining better control over this pressure distribution and the lateral flow (airflow along the sides of the floor), Haas aims to optimize the ground effect generated by the floor. The benefit is a quantifiable improvement in aerodynamic efficiency across all speed ranges – low, medium, and high. This means the car should generate more effective downforce with less drag, leading to better grip in corners and higher straight-line speeds. For a team like Haas, such fundamental improvements are key to consistent performance gains.
AlphaTauri
Front Wing
- Reason for change: Performance – local load
- Difference: “Compared to launch, the outboard end of the front wing is modified to raise the tip elements and add small winglets to the inboard side of the endplate close to its trailing edge.”
- Description: “These modifications reduce the tip losses generated by the assembly that pass inboard of the front tyre. This increases the energy in the flow field downstream and allows the floor in particular to generate more load.”
Elaboration: AlphaTauri’s front wing modifications are a sophisticated exercise in managing intricate airflow dynamics. By raising the tip elements and adding small winglets to the inboard side of the endplate, the team aims to reduce “tip losses.” Tip losses occur when high-pressure air on the upper surface of a wing spills over to the lower-pressure underside at the wing tip, creating vortices and reducing efficiency. By mitigating these losses, AlphaTauri can preserve more energy in the airflow immediately downstream of the front wing. This ‘higher energy flow’ is then directed towards the car’s floor, allowing it to generate more downforce. Essentially, a cleaner and more energetic airflow from the front wing significantly enhances the efficiency and load-generating capability of the floor, which is the cornerstone of modern F1 aerodynamics.
Sidepod Inlet / Mirror Assembly
- Reason for change: Performance – local load
- Difference: “Relative to the launch mirror assembly that only has an aerofoil section above the mirror body, this update adds an aerofoil section below the mirror body as well. An extra winglet has also been added to the outboard mirror stay where it meets the sidepod upper surface.”
- Description: “The addition of the wing element below the mirror body reduces the size of the wake generated by the mirror glass by generating local up-wash behind it. The reduction in wake losses allows the rear of the car to receive higher energy flow, improving downforce generation as a result. The extra winglet provides some additional outwash to help keep front wheel wake losses further away from the bodywork.”
Elaboration: The AlphaTauri update to the sidepod inlet and mirror assembly showcases the minute details F1 engineers scrutinize. The new aerofoil section below the mirror body, coupled with an additional winglet, serves multiple critical functions. Mirrors, despite their small size, create turbulent “wake” behind them, which disrupts the smooth airflow crucial for downforce generation further back on the car. By introducing an aerofoil section, the team aims to generate “up-wash,” effectively cleaning up the airflow and reducing the size and impact of this wake. This ensures that the rear of the car receives a higher energy, less turbulent flow, thereby improving the efficiency of the rear wing and diffuser in generating downforce. Furthermore, the extra winglet on the mirror stay aims to create “outwash,” pushing the disruptive turbulent wake from the front wheels further away from the sidepod bodywork. This prevents the turbulent air from interfering with the sidepod’s aerodynamic performance, ultimately leading to a more stable and higher-performing aerodynamic platform for the entire car.
