McLaren and Red Bull unveiled their 2026 Formula 1 challengers as pre-season testing commenced at the Circuit de Barcelona-Catalunya. The MCL40 and RB22 were revealed via digital renders, with both teams opting for a testing-only black livery to conceal final design details ahead of the season opener in Australia.

The launches coincide with a five-day, closed-door shakedown for the sport's most significant regulation change in decades. With new power units and chassis to master, teams are maximizing limited track time to ensure reliability for the March 8 start. The Barcelona event is self-organized by the teams themselves.

McLaren will run their car from Tuesday, while Red Bull is on track Monday. Both are limited to three of the five days. Fans can watch analysis on Sky Sports, with full livery reveals expected at team season launches ahead of official Bahrain testing in February.
