All through our analyses, we now have typically talked about “aerodynamic load,” “high-downforce circuits,” and “low-downforce circuits.” However what do these phrases imply? How can we differentiate between varied monitor varieties? 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 fans. 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 utterly completely different behaviors from one GP to the subsequent.

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

Let’s begin with the automobiles. In idea, they need to be capable to carry out optimally on any kind of monitor. Nonetheless, this isn’t easy. For that reason, updates are launched to the automobiles through the season. The objective? To search out the best compromise for a selected monitor between downforce (also called “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 exhibits how these two forces act. It’s evident that the load is primarily generated by the automobile’s flooring in trendy autos. That is complemented by the load generated by the wings and the general automobile physique.

Downforce refers back to the drive created by the airflow hitting the automobile, urgent it downward, and holding it glued to the bottom. Larger downforce interprets into higher grip and, consequently, larger cornering speeds. Nonetheless, elevated downforce additionally ends in larger drag, which reduces high pace. In consequence, the facility unit must ship extra energy. Primarily based on these ideas, tracks are categorized as “high-downforce circuits” and “low-downforce circuits.”

Excessive-downforce circuits: how one can acknowledge them

The time period “high-downforce circuit” usually 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 automobile’s downforce is extra necessary than the engine’s energy. Due to this fact, in high-downforce circuits, a good portion of a automobile’s efficiency comes from the downforce it generates fairly than engine energy. Nonetheless, it isn’t correct to say that energy has no impression on efficiency. In truth, larger energy permits groups to go for extra aggressive setups and obtain optimum efficiency. On these tracks, groups use rear wings with larger incidence angles to realize larger downforce and grip in corners. Frequent examples of high-downforce circuits embrace Monaco, Singapore, Mexico, Hungary, and Brazil.

Low-downforce circuits: how one can acknowledge them

The time period “low-downforce circuit” or “energy circuit” usually 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 fairly than downforce. Nonetheless, 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 residence race, groups convey excessive automobile setups that gained’t be used once more through the season. On this case, rear wings have minimal incidence angles to realize larger high speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Similar monitor, differing types: it’s potential

Sure, it’s potential. Throughout the identical monitor, it’s potential to determine 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. For example, McLaren has typically appeared extra aggressive in high-downforce sectors. For that reason, the automobile’s setup is set by discovering the best compromise between downforce and high pace. Moreover, different track-specific elements, equivalent to monitor evolution, grip, and asphalt abrasion, play a task.

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