The three days of the 2022 Barcelona F1 pre-season test concluded with success for many, with a few surprises and a slight foreshadowing of what lies ahead. While some teams have started off strongly, others have a lot of development to do. Most of the teams were occupied trying to understand the new ground-effect technology on the 2022 cars, which is unchartered territory for many.Here are five key takeaways from the F1 preseason test in Barcelona:Charles Leclerc's Ferrari F1-75 takes on the straights of the F1 circuit in Barcelona (Photo by Rudy Carezzevoli/Getty Images)#1 Porpoising Porpoising is essentially F1’s new buzzword, which refers to the car bouncing like a dolphin or a porpoise. Excessive downforce and less suspension control in the car make its floor stick close to the track. When the floor is too close to the track, it stalls and makes the car bounce as a result of the sudden loss in downforce, creating a bouncy movement called porpoising.Most of the cars on the grid were porpoising on the straights, a problem that cannot be necessarily simulated in the best of simulators, therefore a lot of the teams had a reality check with the real-time data collected from the test. Most will return to their factories, however, to find a quick fix or permanent solution to overcome the obstacle.

In the morning session on the final day, however, five red flags were brought out, out of which two were due to stoppages caused by technical failures.While the top teams had minor teething issues, the teams that had a difficult test were Alpine, Aston Martin, Alfa Romeo and Haas. The Alpine team was unable to use its DRS during the test and suffered a hydraulic leak that led to an engine failure on Fernando Alonso’s car. Aston Martin driver Sebastian Vettel’s car had an oil leak leading to smoke coming out of the rear and causing a stoppage for him.Formula 1@F1A total of 3,109 laps were completed by the teams at the pre-season session in Barcelona #F1 @Circuitcat_eng6:30 AM · Feb 26, 202215799833A total of 3,109 laps were completed by the teams at the pre-season session in Barcelona 😮👏#F1 @Circuitcat_eng https://t.co/qYTuuIskamAlfa Romeo's Guanyu Zhou had two off-track moments which led to the car needing severe repairs, which altered his team-mate Valterri Bottas’ track time. Nevertheless, when it comes to engine reliability, Alpine and Aston Martin are the only two teams to have witnessed technical issues. Ferrari, Red Bull, Mercedes and McLaren were able to rack up a significant amount of mileage on their cars, with the scarlet squad topping the overall list.
