All through our analyses, we’ve typically talked about “aerodynamic load,” “high-downforce circuits,” and “low-downforce circuits.” However what do these phrases imply? How can we differentiate between numerous observe 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 fans. There’s been loads of motion on observe 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 often led to single-seaters displaying utterly completely different behaviors from one GP to the subsequent.
However why does this occur? Primarily, two components are concerned. On one hand, it’s in regards to the potential of the vehicles to “digest” sure observe 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 sort of observe. Nonetheless, this isn’t easy. Because of this, updates are launched to the vehicles throughout the season. The purpose? To search out the suitable compromise for a particular observe 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 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 drive created by the airflow hitting the automobile, urgent it downward, and maintaining it glued to the bottom. Increased downforce interprets into higher grip and, consequently, increased cornering speeds. Nonetheless, elevated downforce additionally leads to larger drag, which reduces high velocity. Because of this, the ability unit must ship extra energy. Based mostly on these ideas, tracks are categorized as “high-downforce circuits” and “low-downforce circuits.”
Excessive-downforce circuits: how you can 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 essential than the engine’s energy. Subsequently, in high-downforce circuits, a good portion of a automobile’s efficiency comes from the downforce it generates quite than engine energy. Nonetheless, it isn’t correct to say that energy has no impression 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 larger downforce and grip in corners. Frequent examples of high-downforce circuits embrace Monaco, Singapore, Mexico, Hungary, and Brazil.
Low-downforce circuits: how you can 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 essential than downforce. For these tracks, a good portion of efficiency comes from engine energy quite 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 house race, groups deliver excessive automobile setups that received’t be used once more throughout the season. On this case, rear wings have minimal incidence angles to realize increased high speeds and decrease drag. Frequent examples of low-downforce circuits embrace Miami, Azerbaijan, Canada, and Belgium.
Identical observe, differing types: it’s potential
Sure, it’s potential. Inside the identical observe, it’s potential 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 observe than others. For example, McLaren has usually appeared extra aggressive in high-downforce sectors. Because of this, the automobile’s setup is set by discovering the suitable compromise between downforce and high velocity. Moreover, different track-specific components, resembling observe 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).
