All through our analyses, we’ve 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 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 fully 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 skill 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 be capable of carry out optimally on any kind of monitor. Nonetheless, this isn’t easy. For that reason, updates are launched to the vehicles throughout the season. The purpose? To search out the proper compromise for a selected monitor between downforce (also referred to as “aerodynamic load”) and drag (resistance to ahead movement). Subsequently, it’s essential to grasp the distinction between downforce and drag. The picture under reveals how these two forces act. It’s evident that the load is primarily generated by the automotive’s ground in fashionable autos. 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 retaining it glued to the bottom. Larger downforce interprets into higher grip and, consequently, increased cornering speeds. Nonetheless, elevated downforce additionally ends in better drag, which reduces prime pace. In consequence, 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: learn 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 essential 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. Nonetheless, it isn’t correct to say that energy has no affect on efficiency. In reality, 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 realize better downforce and grip in corners. Widespread examples of high-downforce circuits embody Monaco, Singapore, Mexico, Hungary, and Brazil.

Low-downforce circuits: learn 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, sluggish corners). On this case, engine energy is extra essential than downforce. For these tracks, a good portion of efficiency comes from engine energy slightly than downforce. Nonetheless, 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 residence race, groups convey excessive automotive setups that gained’t be used once more throughout the season. On this case, rear wings have minimal incidence angles to realize increased prime speeds and decrease drag. Widespread examples of low-downforce circuits embody Miami, Azerbaijan, Canada, and Belgium.

Similar monitor, differing types: it’s attainable

Sure, it’s attainable. Inside the similar monitor, it’s attainable to determine each high-downforce and low-downforce sectors. Examples embody Silverstone, Spa, and Austin. Micro-sector analyses have proven that vehicles carry out higher in sure sections of the monitor than others. As an example, McLaren has usually appeared extra aggressive in high-downforce sectors. For that reason, the automotive’s setup is decided by discovering the proper compromise between downforce and prime pace. Moreover, different track-specific elements, similar to monitor evolution, grip, and asphalt abrasion, play a job.

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