Williams test driver Roy Nissany will debut the team's new 2021 Formula 1 challenger at this week's pre-season test in Bahrain.

Williams has revealed Nissany and full-time drivers Nicholas Latifi and George Russell will equally share the three days of running at the Bahrain International Circuit.

Despite testing time being limited to just three days, the Grove-based outfit has opted to reduce the running of its lead two drivers in favour of giving test driver Nissany more track time. 

The Israeli driver was retained by Williams as official test driver earlier in the year after participating in three FP1 sessions during the 2020 campaign.

Alongside his test driver duties in 2020, Nissany raced in Formula 2 for Trident. 

He could only manage two points finishes on his way to 19th in the drivers' championship. For 2021, Nissany will continue in F2 with DAMS.

Williams launched its new car - the FW43B - last Friday through an online reveal

It was meant to unveil the FW43B through the use of augmented reality but its plans were curtailed after the mobile app Williams had planned to use had been hacked.

The FW43B sports a new blue, yellow and white livery, citing back to its historic colour schemes from the 1980s and 1990s.

Pre-season testing in Bahrain kicks off on March 12 at 7am GMT. 

2021 car launches

Ferrari and Haas are the only two teams yet to unveil their 2021 machinery. 

Ferrari is set to launch the SF21 on Wednesday afternoon, while Haas will conduct a physical presentation of its VF-21 car on Friday morning in Bahrain.
