All through our analyses, we’ve got usually talked about “aerodynamic load,” “high-downforce circuits,” and “low-downforce circuits.” However what do these phrases imply? How can we differentiate between varied monitor sorts? We’ll discover these questions on this article with the assistance of our graphics.

Beginning with the fundamentals: aerodynamic load

The 2024 F1 season has undoubtedly delivered thrilling moments for motorsport fanatics. There’s been loads of motion on monitor and a number of other drivers contending for victory. A contributing issue is that some automobiles tailored higher than others to particular tracks all through the season. This often led to single-seaters displaying fully totally different behaviors from one GP to the following.

However why does this occur? Basically, two components are concerned. On one hand, it’s concerning the potential of the automobiles to “digest” sure monitor traits. On the opposite, it’s concerning the tracks themselves.

Let’s begin with the automobiles. In concept, they need to be capable to carry out optimally on any sort of monitor. Nevertheless, this isn’t easy. For that reason, updates are launched to the automobiles in the course of the season. The aim? To seek out the fitting compromise for a particular monitor between downforce (also referred to as “aerodynamic load”) and drag (resistance to ahead movement). Due to this fact, it’s essential to know the distinction between downforce and drag. The picture beneath reveals how these two forces act. It’s evident that the load is primarily generated by the automotive’s ground in trendy automobiles. That is complemented by the load generated by the wings and the general automotive physique.

Downforce refers back to the power created by the airflow hitting the automotive, urgent it downward, and maintaining it glued to the bottom. Greater downforce interprets into higher grip and, consequently, greater cornering speeds. Nevertheless, elevated downforce additionally leads to larger drag, which reduces high pace. Because of this, the ability unit must ship extra energy. Based mostly on these ideas, tracks are categorized as “high-downforce circuits” and “low-downforce circuits.”

Excessive-downforce circuits: acknowledge them

The time period “high-downforce circuit” sometimes refers to tracks the place the prevalence of corners outweighs that of straights (a excessive variety of corners and few straights). On this case, the automotive’s downforce is extra necessary than the engine’s energy. Due to this fact, in high-downforce circuits, a good portion of a automotive’s efficiency comes from the downforce it generates quite than engine energy. Nevertheless, it’s not correct to say that energy has no influence on efficiency. In reality, greater energy permits groups to go for extra aggressive setups and obtain optimum efficiency. On these tracks, groups use rear wings with greater incidence angles to attain larger downforce and grip in corners. Frequent examples of high-downforce circuits embrace Monaco, Singapore, Mexico, Hungary, and Brazil.

Low-downforce circuits: acknowledge them

The time period “low-downforce circuit” or “energy circuit” sometimes refers to tracks the place the prevalence of straights outweighs that of corners (lengthy straights and quick, gradual corners). On this case, engine energy is extra necessary than downforce. For these tracks, a good portion of efficiency comes from engine energy quite than downforce. Nevertheless, it’s incorrect to say that downforce is pointless on low-downforce circuits. Monza is the quintessential energy circuit. It’s estimated that 75% of a lap right here is accomplished with the throttle absolutely open. For this dwelling race, groups carry excessive automotive setups that received’t be used once more in the course of the season. On this case, rear wings have minimal incidence angles to attain greater high speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Identical monitor, differing kinds: it’s potential

Sure, it’s potential. Throughout the similar monitor, it’s potential to establish each high-downforce and low-downforce sectors. Examples embrace Silverstone, Spa, and Austin. Micro-sector analyses have proven that automobiles carry out higher in sure sections of the monitor than others. As an illustration, McLaren has typically appeared extra aggressive in high-downforce sectors. For that reason, the automotive’s setup is decided by discovering the fitting compromise between downforce and high pace. Moreover, different track-specific components, similar to monitor evolution, grip, and asphalt abrasion, play a job.

To conclude, we current beneath a abstract desk of the F1 2024 season circuits with their downforce ranges (Pirelli knowledge).
