Testing Week: What to Watch on Day 2
Day 2 of testing is where the paddock stops introducing the new era and starts interrogating it.

With the 2026 reset (and the Barcelona Shakedown running January 26–30, 2026, with each team allowed three days), Day 2 isn’t about the headline time you’ll never fully trust anyway; it’s about how a car behaves when the track grip comes up, the run plans get longer, and the drivers stop driving around problems and start driving *into* them.
