Now, that is how you answer a challenge. Mattia Colnaghi had briefly planted his machine at the top of the timesheets with a 1:30.671, looking untouchable for a moment. But Taito Kato had other ideas, immediately eclipsing that benchmark by 0.085s with a stunning 1:30.386.
Things were moving fast on track. Keanu Al Ahzari jumped into the mix, briefly going fastest by 0.073s on a 1:30.787, before Dion Gowda pushed hard to reset the benchmark. Gowda punched in a 1:30.935, leaving teammate James Egozi 0.094s behind in a tight intra-team battle. Later in the running, Kato dropped a 1:31.463 to edge ahead of Keanu Al Ahzari by just 0.003s, while Ernesto Rivera kept his strong test rolling by topping the times with a 1:31.584, beating the following pack by 0.075s.
Of course, testing is never entirely clean. Alexander Abkhazava brought out a red flag when he beached his machine in the gravel at Turn 3. Teams played it smart early on, holding their cars in the garages for the first twenty minutes to let others sweep the cold track clean before Pedro Clerot eventually went fastest with a 1:31.659 once running properly resumed. Another brief stoppage followed when Alessandro Giusti suffered an issue in the pitlane, but the action quickly got back underway.
Looking back at Day 1, the margins were razor-thin. Kean Nakamura-Berta finished the opening day on top by a microscopic 0.002s ahead of Mattia Colnaghi. Meanwhile, the Argentinian driver put in a massive shift on the opening day, grinding out 73 laps to complete the most mileage of anyone.
With the Barcelona post-season test already locked in for October 26-27, the field is clearly using every minute available here in Jerez to find their limits.
