Mercedes' Antonelli Tops Timesheets on Penultimate Day of Bahrain Testing

Kimi Antonelli set the fastest time for Mercedes on the penultimate day of 2026 pre-season testing in Bahrain, narrowly edging out McLaren's Oscar Piastri. While lap times remain an unreliable indicator of true performance, the day provided significant technical intrigue as Ferrari debuted a radical rotating rear wing and several teams completed heavy mileage programs, with Max Verstappen logging a field-high 139 laps for Red Bull.

Why it matters:

Pre-season testing offers the first real glimpse of the competitive order and technical innovations for the upcoming season. A top time for Mercedes, combined with strong long-run showings from Red Bull and McLaren, sets an early narrative. However, the true story often lies in reliability, innovation, and consistent pace over single-lap glory, making Ferrari's low-lap but high-innovation day and Aston Martin's stoppage equally critical data points.

The Details:

• Mercedes on Top: Rookie Kimi Antonelli clocked a 1:32.803 to lead the day for Mercedes, just 0.058 seconds ahead of McLaren's Oscar Piastri, signaling a potentially strong start for the Silver Arrows.
• Red Bull's Marathon: Reigning champion Max Verstappen finished third fastest but completed a mammoth 139 laps, the most of any driver, focusing on reliability and long-run data collection for Red Bull.
• Ferrari's Innovation: Despite running only five laps in the morning session, Ferrari was the talk of the paddock after unveiling an innovative active rear wing design where the entire assembly rotates, a bold interpretation of the 2026 aerodynamic regulations.
• Mixed Fortunes: The day saw both productivity and problems. Alpine's Franco Colapinto (120 laps) and Williams' Alex Albon (117 laps) had productive runs, while Aston Martin's Fernando Alonso stopped on track after 68 laps, highlighting potential reliability concerns.
• The Timesheets: Lewis Hamilton was fourth for Ferrari, with Lando Norris fifth for McLaren. Further down, Audi, Haas, and the new Cadillac team continued their acclimatization programs.

What's Next:

All focus now shifts to the final day of testing, where teams will typically run qualifying simulations and race rehearsals to finalize their setups for the season-opening Bahrain Grand Prix next week.

• The data from today's high-fuel runs and tomorrow's final preparations will solidify each team's understanding of their car's true potential and weaknesses.
• Ferrari will be eager to put more laps on its novel rear wing concept, while Mercedes and Red Bull will look to confirm their apparent early speed. The final day will provide the last clues before the competitive veil is fully lifted at the first race weekend.
