F1’s closed-doors Barcelona test is already a success for most participating teams – which makes the efforts to keep it so private even more misplaced
The closed Barcelona test in Formula 1 was initially set up to shield teams from excessive scrutiny and provide a secure environment for new cars and engines to rack up their initial laps. The secrecy component appears to have been unnecessary, given the smooth running and significant achievements witnessed so far in Spain. Teams are cautious not to get complacent despite the promising start with new rules. The nearly 50/50 split engines are performing admirably, and sustainable fuels have not led to any notable issues. Teams surpassed expectations with over 400km on average per day, showcasing impressive preparation and management of the new regulations. The significant progress made on day one reflects the evolution and high standards of Formula 1 compared to the challenging 2014 testing debut.
