The storylines to watch as Formula 1 hits Barcelona

It is officially race week, and the paddock is buzzing as we head to the Circuit de Barcelona-Catalunya for the seventh round of the 2026 season. After the drama of Monaco, we are moving to a venue that offers a totally different test of machinery. The big story, of course, is Kimi Antonelli. He is currently on a stunning run of five consecutive Grand Prix victories, a streak that ties him with none other than Lewis Hamilton. While he is only halfway to the record of 10-in-a-row set by Max Verstappen, his form is simply relentless.

Speaking of Hamilton, he is clearly finding his feet with Ferrari. After a difficult 2024, the seven-time World Champion has secured back-to-back second-place finishes in Canada and Monaco, propelling him to second in the Drivers' Championship. Hamilton believes his first win in Ferrari colors is incredibly close. Meanwhile, the weekend will serve as a critical benchmark for upgrades; as a permanent circuit with high-speed corners, Barcelona finally gives teams three full practice sessions to assess their progress away from Sprint formats or the unique demands of Monaco.

Keep an eye on the Friday morning sessions, as the familiar track is seeing a flood of rookie talent. Colton Herta is set for his first outing in the Cadillac, joined by Luke Browning for Williams and Fred Vesti for Mercedes. Other names like Leonardo Fornaroli at McLaren, Dino Beganovic at Ferrari, Ayumu Iwasa at Red Bull, and Paul Aron at Audi are also getting their chance. Finally, the paddock is waiting for the fallout from the FIA's new ADUO regulations, which allow manufacturers falling behind in power unit performance to introduce extra upgrades.
