All through our analyses, we’ve got 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 several other drivers contending for victory. A contributing issue is that some vehicles tailored higher than others to particular tracks all through the season. This sometimes led to single-seaters displaying utterly totally different behaviors from one GP to the subsequent.

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

Let’s begin with the vehicles. In principle, they need to have the ability to carry out optimally on any kind of monitor. Nevertheless, this isn’t easy. For that reason, updates are launched to the vehicles throughout the season. The purpose? To seek out the precise compromise for a selected monitor between downforce (also referred to as “aerodynamic load”) and drag (resistance to ahead movement). Subsequently, it’s essential to know the distinction between downforce and drag. The picture under exhibits how these two forces act. It’s evident that the load is primarily generated by the automobile’s ground in trendy automobiles. That is complemented by the load generated by the wings and the general automobile physique.

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

Excessive-downforce circuits: the best way to 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 automobile’s downforce is extra vital than the engine’s energy. Subsequently, in high-downforce circuits, a good portion of a automobile’s efficiency comes from the downforce it generates somewhat than engine energy. Nevertheless, it isn’t correct to say that energy has no affect on efficiency. In reality, 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 attain higher downforce and grip in corners. Frequent examples of high-downforce circuits embrace Monaco, Singapore, Mexico, Hungary, and Brazil.

Low-downforce circuits: the best way to 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, sluggish corners). On this case, engine energy is extra vital than downforce. For these tracks, a good portion of efficiency comes from engine energy somewhat than downforce. Nevertheless, it’s incorrect to assert 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 house race, groups convey excessive automobile setups that received’t be used once more throughout the season. On this case, rear wings have minimal incidence angles to attain larger prime speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Similar monitor, differing kinds: it’s doable

Sure, it’s doable. Inside the similar monitor, it’s doable to determine each high-downforce and low-downforce sectors. Examples embrace Silverstone, Spa, and Austin. Micro-sector analyses have proven that vehicles 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 precise compromise between downforce and prime pace. Moreover, different track-specific components, comparable to monitor evolution, grip, and asphalt abrasion, play a task.

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