Lewis Hamilton's Mercedes team have held a secret testing session in a desperate bid to get their 2022 F1 campaign up and running.
In what has been torrid start for the Silver Arrows, and Hamilton in particular, the W13 cars have been way off the pace set by front-runners Ferrari and Red Bull. The seven-time world champion is already 68 points adrift of championship leader Charles Leclerc, ahead of the sixth race of the season in Barcelona this week.
Mercedes have been plagued by 'porpoising' thus far, affecting their straight-line speed. However, Toto Wolff's team are expected to bring a number of new parts to the Circuit de Catalunya in the hope of combating the problem.
