However, after a clean session of running this morning, with Lewis Hamilton having made his official F1 debut for Ferrari, a strange problem hit the drivers in the cars this afternoon.
As we headed into the evening in Bahrain, the circuit suffered a huge power cut, plunging the track into darkness and bringing out the red flag.

FIA announce testing update
This occurred at approximately 5 pm local time in Bahrain, with running ending up being halted for roughly an hour.
With testing time limited across the three days, that is a huge amount of time for teams and their drivers to lose out on.
However, that will now not be the case after the FIA offered an official update.
Although cars did manage to make it back on track under the lights for the final hour of the session, the FIA revealed that they had extended the session time by an hour, therefore mitigating for the lost hour due to the power cut.
As such, testing will now end at 8 pm local time in Bahrain, or noon on the East Coast in the United States.
