All through our analyses, we have now 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 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 fanatics. 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 sometimes led to single-seaters displaying fully totally different behaviors from one GP to the following.

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

Let’s begin with the vehicles. In concept, they need to be capable of carry out optimally on any sort of monitor. Nevertheless, this isn’t easy. Because of this, updates are launched to the vehicles through the season. The objective? To search out the best compromise for a selected monitor between downforce (often known as “aerodynamic load”) and drag (resistance to ahead movement). Due to this fact, it’s essential to grasp 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 drive created by the airflow hitting the automotive, urgent it downward, and holding it glued to the bottom. Larger downforce interprets into higher grip and, consequently, increased cornering speeds. Nevertheless, elevated downforce additionally leads to higher drag, which reduces prime velocity. In consequence, 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: find out how 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 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 fairly than engine energy. Nevertheless, it’s not correct to say that energy has no influence on efficiency. In truth, 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: find out how 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, 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. 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 deliver excessive automotive setups that gained’t be used once more through the season. On this case, rear wings have minimal incidence angles to attain increased prime speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.

Identical monitor, differing kinds: it’s attainable

Sure, it’s attainable. Throughout the identical monitor, it’s attainable 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. As an illustration, McLaren has typically appeared extra aggressive in high-downforce sectors. Because of this, the automotive’s setup is set by discovering the best compromise between downforce and prime velocity. Moreover, different track-specific elements, reminiscent of 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).
