Audi remains out front in qualifying for the Le Mans 24 Hours after the second of three sessions ahead of this weekend's 90th running of the race was hit by poor weather conditions.
Heavy rain before the session got underway led to challenging conditions on track and prevented teams from making a push to improve their lap times from Wednesday evening, with the only improvements coming from those cars that had failed to post a time in the opening session.
The first of two sessions on Thursday kicked off with standing water around much of the early part of the lap and with teams having no option but to with wet weather tyres to gain some kind of grip on track.
Over the course of the opening hour, conditions would gradually improve, with Anthony Davidson being the first man to set something resembling a quick time in the #7 Toyota, albeit a full 20 seconds down on the benchmark time from Wednesday.
Partner Alex Wurz would then take over the wheel of the TS030 HYBRID and improved the car's best time to a 3min 40.9214secs to edge out the #3 Audi by just 0.066secs when the session was halted after an accident at Indianapolis for Matt Downs in the Boutsen Ginion Racing Oreca.
With the barriers damaged, officials elected to halt the session early, with the final qualifying session now starting half an hour early and running for two and a half hours.
John Martin put the G-Drive Oreca-Nissan sixth in the session to lead LMP2 with Jan Magnussen's Corvette heading GTE-Pro. Stuart Hall's Aston Martin led GTE-Am.
Only one car was able to improve on its qualifying position during the session, with Tom Kimber-Smith moving the #41 Greaves Motorsport Zytek up to 33rd on the provisional grid as it set its first timed qualifying laps, while there was also a first timed run for the #32 Lotus T128 – although it wasn't quick enough to move it above 54th spot.
The JMW Motorsport Ferrari returned to the circuit having undergone repairs but failed to set a timed lap before the session-stopping incident, while work is ongoing at Krohn Racing to get its new Ferrari ready for the final session.
The Thiriet by TDS Oreca, which caused the early stoppage in first qualifying, will miss both Thursday sessions as repairs continue.
