Formula 1’s 2024 launch season is in full swing, and teams and journalists are scrambling to uncover the important changes and innovations. Haas’s VF-24 reveal didn’t showcase much innovation, as they wanted to keep their designs under wraps. However, other teams are expected to reveal more in the coming weeks.
The key to spotting these changes lies in understanding where to look. Red Bull’s success can be attributed, in part, to its powerful ground effect venturi tunnels in the underfloor. These tunnels generate significant downforce without causing bouncing issues. The level of detail in Red Bull’s underfloor design, especially after Sergio Perez’s crash in Monaco, was remarkable. The variation in the topography of the underfloor, combined with the suspension characteristics, ensures consistent downforce generation.
While the underfloor details may not be immediately obvious, the sidepods offer a visible area to analyze. The interaction between the sidepods, floor edges, and underfloor is crucial in this generation of cars. It is expected that teams will adopt the Red Bull-style ‘downwash’ sidepod design, which directs airflow downwards via a ramp. Ferrari’s shift away from its scalloped sidepod shape in 2023 makes them a fascinating case study for 2024.
Another important design trend to watch is how the sidepods are packaged to maximize airflow around the sides. Red Bull has led the way in raising the sidepod inlet to enhance the undercut. This improves not only downforce generation but also the car’s overall consistency. McLaren’s sidepod updates in 2023 demonstrated this evolution, with wider and shallower cooling inlets.
The shape of the chassis and the positioning of the driver within the car can also vary. Last year, Lewis Hamilton complained about his cockpit positioning, feeling he was too far forward, impacting the Mercedes’ rear-end feel. The location of the cockpit opening determines how far back the driver sits. Mercedes’ cockpit position may be worth observing closely.
The decision between pushrod and pullrod suspension configurations is another noticeable design choice. Red Bull and McLaren were the only teams to opt for pullrod front suspension and pushrod rear suspension in 2023. This decision primarily affects aerodynamics rather than mechanics. The impact on suspension wishbones and airflow configuration makes it a significant choice for teams.
The interaction between aerodynamic and mechanical characteristics is crucial in optimizing the current ground effect F1 cars. Red Bull has shown mastery in this area, with anti-dive and anti-squat geometry in their suspension. Other teams may replicate these changes, particularly at the rear end, which requires modifications to the gearbox casing.
While F1’s regulations are highly prescriptive, there is still room for innovation and surprises. Teams may introduce small details that go unnoticed at first glance but have a significant impact on performance. The launch versions of the cars may hide these innovations, but they will eventually be uncovered.
In the end, the 2024 cars will serve as a reminder that this process is not simply about copying Red Bull’s direction but also about finding new and innovative ideas. Despite creating an evolutionary car, Red Bull may still surprise everyone with their designs.
Pre-season testing is the first time Formula 1 teams can all run their cars together and get the first clues of who is – and isn’t – going to be competitive in the upcoming season.
