2024 Saudi Arabian GP: Quali session

Quali session deltas

The quali session deltas plot shows all the deltas between the different drivers for all of the 3 quali sessions of the day.

You can read the charts like this:

  1. Choose a driver from the left side of the plot (y-axis)
  2. Choose a second driver from the bottom of the plot (x-axis)
  3. See where they intersect. The number that you see is the delta for their best lap in that quali session.
  4. Negative numbers mean the driver on the left side was faster than the driver he’s being compared to.
  5. Positive numbers mean the driver on the left side was slower than the driver he’s being compared to.
  6. For example: Leclerc on Q3 vs Pérez on Q3. The delta is of -0.282 seconds. This means that Leclerc’s best lap was 0.282 seconds faster than Pérez’s.
Deleted laps
The charts finally considers laps that have been deleted and therefore are not shown here =)

Tale of the session

It’s surprising I didn’t think of this earlier. Often, we witness drivers either advancing or getting eliminated by a mere fraction of a second, sometimes less than a tenth. In such cases, the evolving track conditions play a significant role and can alter the session’s outcome drastically. Even a 30-second difference in sending a driver out for their run could potentially result in a gain of half a tenth or more, depending on the track conditions.

The charts are straightforward but insightful. Each chart displays the three fastest laps for every driver in each session. Now, it becomes evident when the driver was sent out to perform their run, allowing us to assess whether the team’s strategy of sending the driver early or waiting until the end of the session was the right call.

Note
A tire was considered to be new new only if it had a life of only 1 lap when starting the lap, meaning that the tire was only warmed up for one lap and then used for the flying lap.
Extra note
Session time isn’t perfect—it may be off by a minute or so due to data limitations—but the idea is just to show the order in which the drivers were sent out.

Quali best sector times

Best sector times for each driver Sector times from the best lap done by each driver

I’ve decided to add some additional information about the FP2 section to this article. The two charts that I’m showing have very similar information about the best sector times of the session. The difference between them is as follows:

  1. The first chart (Best sector times for each driver) shows the best sector times done by each driver, regardless of the lap those sector times were done. It could’ve been on a random lap and not necessarily on their best flying lap.
  2. The second chart (Sector times from the best lap done by each driver) shows the sector times of each driver for their fastest lap of the session.

Usually, you will see that the best sector times were done during their best lap of the session. Having said that, this won’t always be the case. For example, if a driver had 2 great sector times during a flying lap and then made a mistake on the final sector then chances are his best third sector time was done on an entirely different lap.

Quali top speeds

I think a lot of people like to see what were the top speeds of the session so I’m adding a chart for those too.

Maximum speeds

Quali session summary table

Just as before, I am adding a table that contains most of the information about the quali session.
