> Leclerc was able to keep in front of Piastri at his second stop as well, and both drivers were stationary for just two seconds as their crews swarmed over the cars. But that single stop of Norris' was even faster at 1.9 seconds, and while he was driving slower than his teammate, he held track position at the front and was driving flawlessly.

Wow, I know nothing about F1 racing, but that is a fast tire change. Here's how it works: https://www.youtube.com/watch?v=FE5FGSEQc8Q. Three people on each tire, one single bolt. Full stop over the jack, unbolt, old tire off, new tire on, rebolt, drop and go.

The record is 1.8s. This was after changes were introduced to try to slow down pit stops. I believe in the past signals were sent that the wheels were on before they were fully secured (anticipating that by the time the signal was given to the driver the wheel would be fully secured). A delay was introduced and over a couple of seasons the crews managed to get back to (and beat) their old times.
And there's a lot of redundancy, just waiting to execute the task if anyone or some equipment fails.
On the other hand ... why isn't this fully automated yet?
They specify tires that don’t last a full race and have to be changed because the pit stop as it is is such a core aspect of race strategy.
F1 is a wonderful sport if you're a geek.

The drivers are of course the athletes - they have to spend a couple of hours driving cars at up to 200mph through lateral and longitudinal forces that can exceed 5G, or race in conditions where they can lose 4kgs (9lbs) of weight in sweat - but the edges, the performance gains, it's all in the engines and aero departments back at the factory, the crews getting setups right, the pit stops down into the sub-2s, and so much more.

If you were to ask a casual fan who has won the most World Championships they might suggest in recent history that is Max Verstappen (he's won four). A more serious fan will tell you that Lewis Hamilton (still driving today) is tying with Michael Schumacher (who isn't), with 7 drivers' championships, which is the all-time record.

But a more serious fan might suggest it's Adrian Newey - an engineer who has designed cars that have won 12 constructors' championships and 14 drivers' championships. He is now working at Aston Martin on their 2026 car, when all the regulations are changing and Cadillac is joining as an 11th team.

There is ample geekery on YouTube about various design aspects (Phase changing materials to change airflow over inner brake drums? Rear wings that flex "illegally"? Technical regulation deep dives? It's all there), and there is a sofa-friendly series to get partners interested in "Drive to Survive" on Netflix where you'll get to know all the human personalities, and even a - frankly absurd, but popcorn-worthy fun - Hollywood film starring Brad Pitt.

On race weekends there are teams of hundreds of people back at factories analysing not just their own teams' data, but what data is available from other teams: just over 1m data points a second through 3 practice sessions, a qualifying session, potentially a sprint qualifier and sprint race, and then the race itself.

There are team members who specialise in strategy, some who do nothing but figure out the likelihood of rain and understanding where the prevailing wind is coming from (aerodynamics are critical), and squads of people who think long and hard about tires - the three compounds they can choose from (and they must race a minimum of two per race), pressures, and degradation - and even a few people making sure that the car (which is fuelled to not quite finish the race for weight reasons), is correctly being coasted when needed if a safety car doesn't turn up.

Then there's the simulator setups. There are sims back in the factories with dedicated sim drivers testing setups with engineers, but you can join in at home to a point. The gaming sims are now getting good enough that with a decent wedge or with a visit to one of the F1 arcades, you can get something that, g-forces aside, will give something that's about 80% accurate in terms of track layout and some car setups, which is enough for the lay person to realise how insanely hard it is to get the car setup right and consistently send it around the tracks at those speeds and tolerances.

It's a deep well. It's my favourite sport to watch, and I recommend it to all.

So I picked up watching F1 during the pandemic. I like it but you have to know a bit to really appreciate it so let me give you some basics.

First, it's what's called a constructor series. That is, there are different engine manufacturers and each team builds their own car. Soem components can be shared (ie bought from manufacturers), some can't. The cars are intentionally not identical. Some are just better. There are constraints but teams have a lot lf latitude.

This is as opposed to a spec series 9eg Formula E) where the cars are basically identical. This is a spectrum.

There are 10 teams (11 next year; there have been more in the past). Each team fields 2 cars with 2 drivers. The first 10 places award points (up to 25) to both the driver and the team. The team (constructor) standings at the end of the year award prize money. There is a title for the best team and the best driver.

The fact that there are 2 drivers and they both want to win the drivers championship. This creates a ton of tension and conflict.

Because there are only 20(ish) drivers in a season, the individual personalities matter. The complete polar opposite of this is probably the NFL, which has I believe ~1700 full time players in any given year, probably not even including practice squads.

There is now a constructor (and engine) cost cap. That's relatively new (since 2022). Before that some teams would spend 2-3x+ what other teams did, kinda like MLB.

So because there are unequal cars, there are periods of dominance. Currently the clear #1 car is fielded by McLaren. Previously that was Red Bull. Then for a long time it was Mercedes. Sometimes (notably in 2021) there was a close fight between 2 teams for both championships.

The current engine regulations are for a hybrid engine with ground effect cars. Next year it's even more hybrid but they're getting rid of ground effect.

There are currently 24 races in a season going from March to early December with some breaks in between. Race weekends generally run from Friday to Sunday. The format is to have 3 free practice ("FP") sessions on 2 days, each lasting an hour, where teams can change their setup, run different tires and have different run plans to fine tune their setup.

The second session on the Saturday is qualifying (often just "quali") in 3 sessions. In each session each driver is trying to do the fastest single lap possible. In the first 2 sessions the bottom 5 drivers are eliminated. They have a tire allowance for all this that I won't go into. But the starting order for the race (on Sunday) is set from fastest to slowest times. These sessions are called q1, q2 and q3.

The actual race typically runs ~300km (Monaco is less). With different lap lengths that's a different number of laps. In the current regulations the cars are fully-fueled at the start. Previously there was in-race refuelling but no more, for safety reasons.

Tires will last a varying number of laps and there are 3 compounds to use, called soft, medium and hard. There's more complexity to this but I'll ignore that. You have to use at last 2 differnt compounds in the race. That's what the pit stops are, to change tires and possibly a broken front wing (and, as I said, previously refuelling).

The starting order and finishing order are usually called p1 to p20. The top 3 places are also called podium places because, well, you get a trophy. On a podium.

There's more to it like sprint races and how wet weather changes things as well as safety procedures like safety cars, red flags and yellow flags.

But when you go beyond this, you get into the lore, which is both fascinating and hilarious, like industrial espionage on teams that was exposed by a Kinko's employee or someone intentionally getting a driver to crash to affect the world championship or the two childhood friends who ended up teammates and ended up not speaking to each other after a bitter championship fight.

Would love to know how such high performing teams operate and execute.
You might like this video[1]. The driver crashed on his way to the grid. The team had a very limited amount of time to fix the car, on the grid. The video includes radio communication between the various parts of the team and they organise equipment, analyse the issue, and make sure they comply with the various rules. Really fascinating to see how something like this is managed so calmly.

The Hungarian circuit is very difficult for overtaking. Therefore, the front-runner has a much better chance of winning, making tire changes a critical issue.
Fast tire changes only matter a very limited amount of the time (pretty much only if the extra time drops you a place, so there has to be 1 car/20 in a specific 1 second window on what is typically a 90s lap for 3s (a slow stop) vs 2s (a fast stop) to matter. Maybe 20% of the time a slow stop happens, it costs a driver.

Strategy matters a lot and good strategy is worth at least a few positions in a race.

You're forgetting the offset from undercutting. The cars don't need to be within 1s on track for it to matter - you could be within 4s and that extra 0.5s in the pit stop costs you the position if you pit later. Un-lapped 'traffic' is also critical. If you're trying to find a gap to pit into and it's tight an extra second could put you behind a slow car and cost you 'real' positions later.
I've been watching Netflix's "Drive to Survive." One of the most frustrating aspects of it is the team will talk about strategy, but will never say what their strategy is. They'll say the car needs improvement, then say the car is improved, but never say what they did to improve it. They'll say they need to negotiate to get driver X, but never give any hint over what the negotiations were.

Watch it for a while, and you'll see. You never get any real information.

That's because DTS is for people who don't watch the sport. To get them interested. If you've watched the sport for any significant length of time DTS is basically hell on earth to watch. They even go as far as showing footage in the wrong order (turn 1, turn 12, turn 4) to fit their narrative.

There are great technical writers that do pretty in depth analysis (including drawings) of all upgrades teams bring to their cars. I don't know the names off hand but I've seen these as far back as the early 00's. Strategy is covered pretty well on the live broadcast too by ex-strategy engineers.

I remember when they asked Senna what his F1 strategy was. He replied "start in the pole position, and stay in front!"
