2026 F1 Testing Begins: Mercedes Hits Track Immediately, Red Bull Takes Aggressive Tyre Stance

The 2026 Formula 1 season has officially commenced with pre-season testing underway at the Circuit de Barcelona-Catalunya. Mercedes has confirmed it will roll out immediately on Day 1, joining Red Bull and Alpine on track, while Ferrari and McLaren have opted to delay their initial runs. Tyre allocations have also been revealed, highlighting a stark contrast in strategic philosophy between the top teams regarding the new Pirelli compounds.

Why it matters:

With the new 2026 regulations introducing significant changes to power units and aerodynamics, maximizing track time is critical for identifying reliability issues early. Mercedes' decision to run immediately suggests confidence in their build, while Red Bull's aggressive tyre selection indicates a specific focus on qualifying pace and single-lap performance data right out of the gate.

The details:

• Mercedes' Plan: The Brackley-based team has finalized its approach for Day 1, with George Russell and Andrea Kimi Antonelli scheduled to share driving duties. The decision was influenced by favorable weather forecasts expected in Montmeló.
• Track Activity: Mercedes joins Red Bull Racing, Racing Bulls, and Alpine in heading out immediately. Conversely, McLaren and Ferrari have chosen to hold back, potentially prioritizing preparation or waiting for optimal track conditions.
• Tyre Strategy Split: Pirelli has provided C1, C2, and C3 compounds for the test, corresponding to hard, medium, and soft tyres.
  • Red Bull's Aggression: The reigning champions have selected a bold allocation, taking 18 sets of the soft C3 tyre and zero sets of the medium C2.
  • Ferrari's Caution: The Scuderia has taken the opposite approach, selecting just three sets of softs while stocking up on 12 sets of the medium compound to focus on long-run data.

Looking ahead:

As the first day unfolds, the immediate focus will be on completing installation laps and ensuring the new 2026 packages are reliable. The divergent tyre strategies will provide an early, albeit limited, glimpse into how teams are interpreting the performance characteristics of the new generation of F1 cars.
