All through our analyses, now we have typically talked about “aerodynamic load,” “high-downforce circuits,” and “low-downforce circuits.” However what do these phrases imply? How can we differentiate between numerous 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 sometimes led to single-seaters displaying fully completely different behaviors from one GP to the subsequent.

However why does this occur? Primarily, two elements are concerned. On one hand, it’s in regards to the means 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 concept, they need to be capable to carry out optimally on any kind of monitor. Nevertheless, this isn’t easy. Because of this, updates are launched to the automobiles in the course of the season. The purpose? To seek out the correct compromise for a particular monitor between downforce (often known as “aerodynamic load”) and drag (resistance to ahead movement). Subsequently, it’s essential to grasp 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 automotive’s flooring in fashionable automobiles. That is complemented by the load generated by the wings and the general automotive physique.

Downforce refers back to the pressure created by the airflow hitting the automotive, urgent it downward, and maintaining it glued to the bottom. Increased downforce interprets into higher grip and, consequently, greater cornering speeds. Nevertheless, elevated downforce additionally ends in better drag, which reduces prime pace. Because of this, 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 way 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 automotive’s downforce is extra necessary than the engine’s energy. Subsequently, in high-downforce circuits, a good portion of a automotive’s efficiency comes from the downforce it generates slightly than engine energy. Nevertheless, it isn’t correct to say that energy has no affect 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 better downforce and grip in corners. Frequent examples of high-downforce circuits embrace Monaco, Singapore, Mexico, Hungary, and Brazil.

Low-downforce circuits: the way 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 quick, sluggish corners). On this case, engine energy is extra necessary than downforce. For these tracks, a good portion of efficiency comes from engine energy slightly 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 totally open. For this dwelling race, groups convey 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 prime speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Identical monitor, differing types: it’s potential

Sure, it’s potential. Inside the similar 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. As an example, McLaren has usually appeared extra aggressive in high-downforce sectors. Because of this, the automotive’s setup is set by discovering the correct compromise between downforce and prime pace. Moreover, different track-specific elements, resembling 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 knowledge).
