Formula 1 teams return to the Bahrain International Circuit for the final three days of pre-season testing before the 2026 season opener in Australia. The crucial test sessions begin Wednesday at 7am local time, with all 11 teams fine-tuning their new cars under the radical 2026 regulations. Sky Sports F1 provides live coverage throughout the sessions.

Last week's opening test revealed early performance indicators, with teams completing extensive mileage to validate their designs. The new technical rules represent the most significant regulatory overhaul in years, affecting everything from power unit configurations to aerodynamic packages. Teams used the first test to establish baseline performance and identify development priorities for the final pre-season running.

Wednesday's driver lineups feature a mix of race drivers and reserve drivers across the grid, though some teams continue to finalize their schedules. The testing window offers teams their last opportunity to resolve reliability issues and optimize setup before the season begins. Performance data from these sessions will be critical in shaping team strategies for the Australian Grand Prix, where the true competitive order will begin to emerge.
