George Russell has described his first visit to Mercedes High Performance Powertrains factory in Brixworth as "eye-opening".
The Briton will mark his official debut with the team at the Bahrain Grand Prix 15 months on from his stand-in appearance for new team-mate Lewis Hamilton at the same venue - albeit on the outer loop.
After taking time off to recharge since his move from Williams over the winter, Russell has made his first appearance as an official Mercedes driver at the two factories in Brackley and Brixworth.
Addressing the HPP staff in a video posted by Mercedes, Russell said: "Thank you for the warm welcome.
"It is my first time here at Brixworth so it is pretty special to see what goes on behind the scenes because I think quite often, you don't appreciate what goes into creating this incredible machine.
"When you arrive at the track and you see the end product, you don't see all the hard work that goes into making it so this was eye-opening for me."
