Norris Leads Barcelona Practice as Antonelli Struggles with Pace

Lando Norris set the benchmark during Friday's practice sessions at the Barcelona-Catalunya circuit, narrowly edging out George Russell for the fastest lap. While the top contenders showed strong stability, the primary talking point of the weekend has been Kimi Antonelli, who appeared significantly off the pace during his initial runs in the 2026 Mercedes machinery.

Why it matters:

With the 2026 technical regulations introducing radically different power units and aerodynamic philosophies, these early sessions are critical for benchmarking. The disparity in pace between the seasoned veterans and a rookie like Antonelli underscores the immense complexity of the new regulations, where fine-tuning the balance between energy recovery and raw aero efficiency is more volatile than in previous eras.

The details:

• Front-Runner Pace: Norris's McLaren demonstrated exceptional stability through the high-speed corners of Sector 3, maintaining a slight edge over the Mercedes duo.
• The Rookie Gap: Kimi Antonelli struggled with consistent lap times, frequently battling oversteer in the mid-speed sections, leaving him adrift of the top ten.
• Technical Struggles: Early telemetry suggests Antonelli is struggling to optimize the deployment of the new 2026 power unit's electrical output during corner exit.
• Mercedes Internal Delta: George Russell's ability to stay within striking distance of Norris suggests the car has the inherent pace, shifting the focus toward Antonelli's adaptation process.

The big picture:

McLaren's continued dominance in early practice sessions confirms they have transitioned seamlessly into the 2026 era. For Mercedes, the priority is now managing the psychological and technical integration of Antonelli. The team must determine if the rookie's lack of pace is a result of a conservative setup or a genuine struggle to master the new aerodynamic platform.

What's next:

Teams will spend the remaining practice hours refining their setups for a high-fuel race trim. The critical narrative heading into qualifying will be whether Antonelli can bridge the gap to his teammate or if he will continue to struggle as the weekend progresses.
