Formula 1's first track action for the new era began quietly in Barcelona this week. The shakedown test runs Monday through Friday behind closed doors, with no media or fans present. All 11 teams have the opportunity to run for three of the five days, marking the unofficial start of the 2026 season.

The unusual January timing stems from the sport's most comprehensive regulation overhaul in decades. Teams need extra time to adapt to the new hybrid power units, which must deliver 50% of their power from the battery. This marks a similar approach to the 2014 power unit change, where Red Bull famously managed only 21 laps at the first test.

Bahrain hosts the first official test in February, creating a contractual reason for the low-key Barcelona event. Being closer to European factories allows teams to fix issues quickly. The real drama will begin when cars hit the track, as new engine suppliers Audi and Red Bull Powertrains join the grid.
