Lewis Hamilton topped the timesheets with a 1m16.348s lap for Ferrari on the final day of the private Barcelona shakedown test, edging out Mercedes' George Russell by 0.097 seconds. The five-day event allowed teams to debut their 2026 cars amid major regulation changes, focusing on reliability rather than outright pace. Mercedes completed the most laps at 500, signaling their pre-season favoritism.
The Barcelona shakedown, held from Monday to Friday at the Circuit de Barcelona-Catalunya, marked Formula 1's first on-track runs for the radically redesigned 2026 cars. New regulations introduced engines with 50% electrical power output, the removal of the MGU-H component, fully sustainable fuels, and smaller chassis with active aerodynamics via moveable wings.
Mercedes emerged as early frontrunners, completing 500 laps across three days—Monday, Wednesday, and Thursday—more than any other team. George Russell set a benchmark time of 1m16.445s on Thursday, while rookie Kimi Antonelli ran a full race simulation. Russell praised the car's intuitiveness: "It is very different, but when you wrap your head around it, it feels quite intuitive."
Ferrari showed strong reliability, amassing 440 laps. Hamilton's late 'glory run' on soft tires on Friday secured the overall fastest time, with Charles Leclerc third at 1m16.653s. Hamilton noted the car's fun handling: "The car generation is actually a little bit more fun to drive—it's oversteery, it's snappy and sliding, but it's a little bit easier to catch."
McLaren, world champions in 2025, recovered from a Thursday fuel issue to log solid mileage, with Lando Norris second-fastest at 1m16.594s and Oscar Piastri fourth. Red Bull's in-house Ford engine debuted reliably, despite Isack Hadjar's Tuesday wet-weather crash; Max Verstappen completed 118 laps on Friday.
Aston Martin, featuring Adrian Newey's first design, arrived late and managed only 65 laps, with Fernando Alonso completing 61 on Friday. New teams Audi and Cadillac faced teething issues but gained valuable data. Williams skipped the test due to unreadiness.
Leclerc highlighted paddock excitement: "There is a lot of excitement, not only in Ferrari but around the whole paddock." Teams now prepare for official Bahrain tests on February 11-13 and 18-20, before the season opener in Australia on March 6-8.
