Barcelona F1 test – Day 1: Red Bull’s Hadjar leads the way

Red Bull wasted no time stamping its authority on Formula 1’s tightly guarded private test in Barcelona, as new recruit Isack Hadjar set the pace on a dramatic opening day behind closed doors.

With security high, information tightly controlled and live timing quietly disappearing partway through the session, those inside the paddock were left piecing together clues from fleeting glimpses on the timing screens.

What was clear, though, was that Red Bull had arrived ready.

Red Bull and Mercedes Trade Blows

From the moment the cars hit the Circuit de Barcelona-Catalunya, Red Bull and Mercedes emerged as the headline acts. The two teams repeatedly swapped the top spot, hinting at a familiar duel as F1’s next chapter begins to take shape.

Hadjar, stepping into life as a full Red Bull driver, looked immediately at home. Running predominantly on Pirelli’s C3 soft compound, he steadily improved through the day before delivering the benchmark lap: a 1m18.159s.

It left the Red Bull-powered RB22 more than half a second clear of the field – even if it remained well shy of last year’s Spanish Grand Prix pace.

Mercedes, meanwhile, split duties between generations. Rookie Kimi Antonelli impressed during the morning session and briefly stood as Hadjar’s closest challenger, before George Russell climbed into the W17 for the afternoon and secured second place overall.

Red Flags, Rookies and Heavy Mileage

The day wasn’t without interruption. Alpine triggered the first red flag of the test, but Franco Colapinto recovered well to place the Mercedes-powered car third after running the entire day.

If consistency had a prize, it would have gone to Esteban Ocon. The Haas driver racked up a staggering 154 laps – comfortably the highest total. Mercedes wasn’t far behind when combining Antonelli and Russell’s efforts.

For newcomers Audi and Cadillac, however, it was a tougher introduction. Audi’s day unravelled early after a stoppage with Gabriel Bortoleto at the wheel, bringing out a red flag and effectively ending its running.

Cadillac did manage laps with Valtteri Bottas and Sergio Perez, but persistent issues limited track time, with Perez barely reaching double figures.

As the blacked-out Barcelona test rolls on, the cast will continue to grow. McLaren and Ferrari are set to join the action on Tuesday, but Aston Martin will make a late appearance later in the week — while Williams sits this one out entirely.

For now, though, the opening headline belongs to Red Bull and Hadjar: a fast start, a quiet statement, and an early glimpse of what may be to come.
