The opening session of the Le Mans 24 Hours test day featured an incident involving Toyota's #8 car, which collided with the #25 Algarve Pro Oreca 07, leading to a red flag. Despite this, Cadillac's Filipe Albuquerque topped the timesheets with a lap of 3m27.011s, narrowly beating the #35 Alpine A424 by 0.328 seconds. The session began productively, with all 18 Hypercar entries recording timed laps within the first half-hour. Initial fast laps were set by Will Stevens in the #12 Cadillac V-Series.R. However, the session was interrupted by a safety car drill lasting nearly 40 minutes. Following the resumption, a Full Course Yellow was deployed to clear debris after the Toyota incident. The recovery was swift, allowing drivers to make final attempts to improve their lap times before the session concluded. The next three-hour session is set to take place later in the day, providing teams another opportunity to refine their performance ahead of the race.
