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 numerous 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 lovers. There’s been loads of motion on monitor and a number of other drivers contending for victory. A contributing issue is that some vehicles 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 following.

However why does this occur? Basically, two elements are concerned. On one hand, it’s in regards to the capability 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 idea, they need to be capable to carry out optimally on any kind of monitor. Nonetheless, this isn’t easy. Because of this, updates are launched to the vehicles in the course of the season. The objective? To seek out the best compromise for a particular 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 flooring 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 conserving it glued to the bottom. Larger downforce interprets into higher grip and, consequently, increased cornering speeds. Nonetheless, elevated downforce additionally leads to higher drag, which reduces high pace. Consequently, the facility unit must ship extra energy. Based mostly on these ideas, tracks are categorized as “high-downforce circuits” and “low-downforce circuits.”

Excessive-downforce circuits: methods to 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. Subsequently, in high-downforce circuits, a good portion of a automobile’s efficiency comes from the downforce it generates fairly than engine energy. Nonetheless, it’s not correct to say that energy has no affect on efficiency. Actually, increased energy permits groups to go for extra aggressive setups and obtain optimum efficiency. On these tracks, groups use rear wings with increased 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: methods to 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 brief, 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 totally open. For this residence race, groups convey excessive automobile setups that gained’t be used once more in the course of the season. On this case, rear wings have minimal incidence angles to attain increased high speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Identical monitor, differing kinds: it’s doable

Sure, it’s doable. Inside the similar monitor, it’s doable to establish 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. Because of this, the automobile’s setup is set by discovering the best compromise between downforce and high pace. Moreover, different track-specific elements, akin 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).
