All eyes are on the Williams garage ahead of the third day of testing in Barcelona. The struggling British team missed the first two days of 2019 running, amid rumours of design flaws and the potential departure of technical boss Paddy Lowe.
One Williams insider was reported to have said it would be "a miracle" if the FW42 made its test debut on Wednesday.
Rookie driver George Russell, though, said he was "confident" Williams' predictions of running on Wednesday are accurate.
"Everyone is working as hard as possible to get it sorted," the reigning F2 champion added.
A team spokesman said running before lunch on Wednesday was "unlikely", but the car has finally arrived at the Circuit de Catalunya from Grove.
[UPDATE on @WilliamsRacing] - the team’s FW42 car arrived at the circuit at around 4am this morning. There’s unlikely to be any running this morning as the team say there is still work to do to prepare the car. Hopefully we’ll get to see some laps this afternoon. #F1Testing — Rob Watts (@robwattsf1) February 20, 2019
It is an alarming situation for the once-great team's fans, including those of returning F1 driver Robert Kubica.
"As this goes on, surely someone will lose their job," correspondent Krystian Sobierajski, of the Polish broadcaster Polsat Sport, said.
Technical chief Lowe is reportedly the one most under pressure, with reports suggesting that a fundamental design error is to blame for the delay.
Former F1 driver Marc Surer told Speed Week: "If the new car is again bad, I honestly do not know what will become of Paddy Lowe.
"This is his last chance."
