With the Formula 1 fever spreading like a pandemic, it’s important to get up to speed with all its rules, regulations, and lingo. As a fan dives deeper into the world of F1, attempting to broaden their horizons with the nitty-gritty of the sport, they quickly scratch the surface of the important rules with regular consumption of the sport. However, there are still some aspects that don’t get enough attention and get talked about as often. We’re going to discuss one such aspect, which is the F1 out-lap and in-lap. So you can store it in your F1 memory bank and use it as you please.

We are all aware of the all-important qualifying session during a weekend and its different types. During the session, which determines the starting position of each driver on race day, we often see and hear David Croft and Martin Brundle use terms like ‘out-lap,’ which also makes a frequent appearance on the timing board. So, let’s understand all these terms thrown around during a qualifying session and their importance.

What is an out-lap in F1, and what is its significance?

An out-lap is the first lap the drivers embark on right after leaving the garage and getting on the track. We see this scenario in every part of the qualifying session by each and every driver on the track. What is its significance? Let us tell you!

An out-lap is the first and crucial step the drivers take to get their car in the right window. The out-lap is slow and is used to warm the tires and brakes up enough to get the car ready for a fast lap or hot lap. This out-lap is crucial as, without the right temperature in the tires and the brakes, the cars tend to skid off the track and kiss the barriers or play with the gravel.

The out-lap not only ensures there is enough temperature in the tires and breaks but also lets drivers get a feel of the track before they embark on a flying lap (another name for a hot lap). This is precisely why we see the drivers weaving on the track with their cars like they’re bumper cars. It’s essentially to get the right temperature in the tires, and once they feel confident, toward the end of an out lap, the drivers speed up right after the last corner to start their hot lap, which gets their timing on the board.

Safe to say, an out lap is the qualifying equivalent of a formation lap. Now let us talk about what comes after the out lap.

What is a hot lap during qualifying?

Hot, flying, or fast. These are the terms used to talk about a lap where the drivers register their qualifying times on the board. Every driver needs to register at least one hot lap time on the board in all of the sessions they take part in. However, more often than not, the drivers register two in each of the Q1, Q2, and Q3 sessions.

The purpose, as we are all aware, is to set the grid for the race. The hot lap is the most important part of a qualifying session, and it’s when the drivers go the fastest as they push the limits of their F1 challenger. So, impeding a driver during their hot lap even warrants a grid penalty, which is a possible scenario considering that many cars are on the track during each qualifying session.

However, after a hot lap, the drivers instantly start thinking about the next steps, which brings us to the last terminology, an in-lap.

What is an in-lap and its purpose?

Taking the qualifying session as a sprinter’s routine on the track, an out-lap is the warmup, a hot lap is the sprint, and in those terms, an in-lap is the cool down. The in-lap serves the purpose of preserving the important fresh rubber on a tire as the drivers make their way back to the pits.

The in-lap comes right after a hot lap, and the purpose of driving slowly back to the pits, which the drivers do after the race as well, is to cool the car down and not put it under more stress. This lap cools down the tires and breaks to stop the graining process to get the best out of a “used set of tires” during the race.
