Overview
- Filipe Albuquerque put the Wayne Taylor Racing #101 Cadillac fastest in the morning with a 3:27.011 lap, with Alpine and the Hertz JOTA Cadillac close behind.
- The No. 8 Toyota and the No. 25 Algarve Pro Oreca collided at the Goodyear Chicane, leaving the Toyota with heavy left‑rear damage and both cars unable to return to the pits under their own power.
- Race Control staged a nearly 40‑minute safety‑car procedure and later deployed a Full Course Yellow, which reduced on‑track time and limited opportunities for long runs.
- Teams used the session to run reserve drivers, with Jamie Chadwick and Esteban Masson logging their first Hypercar laps, while AF Corse topped both LMP2 and LMGT3 in the morning.
- Because Test Day mixes mandatory checks, procedural drills and differing fuel and tyre programmes, lap times are not definitive, but the Hypercar field being covered by under three seconds points to a very close battle that will shape setup and repair priorities ahead of afternoon running.
