For the 2020 season, F1 has reduced pre-season testing from eight days to six. While six days might still sound like plenty – especially if you see cars putting in lap after lap without any obvious reliability issues – bear in mind that track running is limited to eight hours a day, four in the morning, four in the afternoon after a one-hour lunch break. So, teams effectively have only 48 hours on-track to test their cars. That’s not a whole lot, considering that our F1 car consists of over 10,000 parts, the vast majority of which have been changed and upgraded for the new season. Making sure that all systems work as intended while also building an understanding of how to extract the maximum performance from the new car makes for very long days at the track and is the reason that the lights in the garage aren’t switched off for testing. There’s always more work to do, which is why F1 teams work with a special night shift crew during pre-season tests to maximise the work that can be done in Barcelona. But the shortened pre-season test doesn’t just impact the programme of the team at the track, it also has a massive influence on the work the team has done at the factories over the past weeks and months. In order to make sure that the test in Barcelona runs as smoothly as possible, both Brixworth and Brackley have put in a lot of effort to try and test every single system of the car to reduce reliability risks as much as possible.
