Porsche topped the times in every session over the course of the two-day official World Endurance Championship test at Paul Ricard.
The fastest time overall went to Neel Jani in the #18 Porsche 919 Hybrid, in which the Swiss set a 1m37.220s during the Friday night session.
The Swiss driver recorded the time during a qualifying simulation run early on in the two-hour period before darkness had fallen.
His two team-mates in the #18 car, Marc Lieb and Romain Dumas, also each attempted a qualifying run, both setting times in the 1m37s bracket.
