The rain may have disappeared by accidents and red flags still struck the morning warm-up in preparation for the 24 Hours of Le Mans.

Audi topped the charts with Andre Lotterer setting the fastest time in a session that was disrupted by crashes by two LM P2 machines.

Paul-Loup Chatin went off early in the session and suffering impact with the barriers in the Paniz Barthez Ligier.

While the rain has stopped, there were still a couple of wet patches and this caught out David Cheng who spun into the barrier near Indianapolis with 10 minutes remaining.

Lotterer set the fastest lap of 3:25.886, 1.243s clear of the No. 6 Toyota of Kamui Kobayashi and the No. 2 Porsche 919 Hybrid of Marc Lieb.

Nissan-power again topped the timesheet in LM P2 but Michael Shank Racing’s Honda-powered Ligier threatened to be second fastest.

Changes to the GTE-Pro balance of performance overnight enabled teams to run with their new settings this morning. The pole-winning Ford now runs with an extra 10kg of ballast and a reduction of boost pressure. The fast Ferrari also has 15kg added to their race weight.

Both the Corvette and Aston Martin now have a slightly larger restrictor while the Porsche is unchanged.

The changes didn’t stop Dirk Mueller from again setting the fastest lap at 3:57.397.

In GTE-Am, the WeatherTech team attempted to make a driver change with Cooper MacNeil becoming ill overnight. Gunnar Jeannette was on standby to take over the role after driving at the test day but the request was denied by the ACO – leaving the team with just two drivers for the race.

The 24 Hours of Le Mans goes green at 3:00pm
