Williams has been forced to extend the delay of its 2019 pre-season testing debut, confirming the the FW42 will likely not appear on track until Wednesday “at the earliest.”

The team confirmed on Sunday that it would miss the opening day of Formula 1 pre-season testing at the Circuit de Barcelona, as its new 2019 car was not ready to run.

The news followed the cancellation of a filming day scheduled for Saturday, in which the FW42 was planned to have a shakedown.

Deputy team principal Claire Williams has now confirmed that the new car will not make an appearance on the second day of testing.

“It is looking more likely than not that we will now not be in a position to run on track until Wednesday at the earliest,” she said.

“This is obviously extremely disappointing, but it is unfortunately the situation we are in. We will be getting the FW42 on track as soon as we are able.”

Reigning Formula 2 champion George Russell, who will make his F1 debut with Williams this season, was scheduled to run on Tuesday morning, with the team’s reserve driver Nicholas Latifi set to take over in the afternoon.

If Williams is able to run on Wednesday, Latifi is scheduled for the morning session before Robert Kubica – who makes an F1 race comeback this season after injury cost him a his seat in 2012 – is planned to jump in for the afternoon.
