The Formula 1 circus has arrived at the Bahrain International Circuit for the first day of winter testing. We will get the first indications of how the land lies ahead of the 2024 Formula 1 World Championship opener next weekend. Red Bull Racing will be hoping they will be on top again, whilst Mercedes, Ferrari, McLaren and others hope to have at least closed the gap.
