Formula 1's 2026 pre-season testing kicked off in Barcelona on Monday, with McLaren and Red Bull both revealing their new challengers for the upcoming campaign.
The reigning champions, who secured both the drivers' and constructors' titles last season for the first time in over two decades, presented their MCL40 wearing an all-black temporary livery exclusively for this week's running.
McLaren plan to showcase their official race colours at a dedicated launch event scheduled for February 9.
Meanwhile, Red Bull released carefully composed studio images of the RB22, with angles selected to conceal significant design elements from rival teams and observers.
The RB22 represents a watershed moment for the Milton Keynes outfit, marking their debut with a power unit manufactured entirely in-house.
This engine has been developed in partnership with American automotive giant Ford, ending Red Bull's reliance on external suppliers.
The team had previously unveiled its new livery at an event in Detroit on January 15, though that presentation featured only a show car rather than the actual racing machine.
Unlike some competitors, Red Bull chose not to conduct any shakedown running before the Barcelona test, meaning the RB22 will make its track debut during this week's sessions.
