Russian driver Sergey Sirotkin will be the latest name added to the honour role of Formula 1 drivers next month.
The 22-year-old steps into the Williams seat vacated by Felipe Massa. His FW41 will be sporting the number 35 when it rolls onto the starting grid for the Australian Grand Prix in four weeks' time.
A new start for Sirotkin means a new look, and the rookie driver has just unveiled his new helmet for the forthcoming campaign.
"Getting ready for testing," he wrote on social media site Instagram along with a picture of his new lid.
The new look combines the classic colours of team sponsor Williams on the top with a blue band for personal backers SMP Racing at the bottom.
Sirotkin's picture also shows his race boots, water bottle and HANS device laid out in readiness for the start of testing.
All teams are taking part in the four-day pre-season test session at the Circuit be Barcelona-Catalunya. Sirotkin will be sharing driving duties with his new team mate Lance Stroll on Monday.
On Tuesday, Sirotkin will be back behind the wheel again. But this time he'll be diving the track time with Williams' reserve driver Robert Kubica.
Sirotkin will sit out Wednesday before returning on the final day of the test, once again paired with Stroll.
There will be a second four day test the following week. After that, the cars will be crated up for dispatch to Melbourne.
"I feel really excited ahead of the season," Sirotkin said this week. "I’ve spent a lot of time at the factory, I’m almost living there at the moment!
"It’s busy times, but I am really enjoying it. I’m getting ready for the season in the best possible way."
