The best social media from Day 4 in Barcelona

The penultimate day of the F1 Barcelona Shakedown saw teams rigorously testing their new machinery ahead of the 2026 regulations. Notably, Aston Martin made its debut on track with the Adrian Newey-designed AMR26, driven by Lance Stroll. McLaren's Oscar Piastri also got his first feel for the new MCL40. This private five-day shakedown, a departure from last season, offers crucial data gathering opportunities before the official pre-season tests in Bahrain. Other drivers like Andrea Kimi Antonelli, George Russell, Charles Leclerc, Lewis Hamilton, Liam Lawson, and Sergio Perez also logged valuable track time, as teams prepare for the exciting season ahead.
