Le Mans 24 Hours: Mark Webber keeps Porsche in front of Audi

The longer pitstop for the driver change in the Porsche allowed the Audis of Benoit Treluyer and Filipe Albuquerque to close the gap, but both were coming to the end of quadruple stints, meaning they would have to also perform driver changes at their next stops.

Both Audis appeared to have the measure of Webber, who was severely baulked a few times in traffic in his early laps, meaning he looked set to be fighting a rearguard action as his stint developed.

The #18 and #19 Porsches continued to hold top five positions, having suffered earlier in the race with a suspected slow puncture and a safety car pitstop respectively.

While Lucas di Grassi continued to fight to make the recovering #8 Audi (which was crashed by Loic Duval) a lead-lap regular, behind him Toyota's struggles continued.

Anthony Davidson pitted the #1 TS040 with bodywork and rear suspension damage towards the start of the hour, resulting in a 13-minute stop in the garage for repairs before the car was taken over by Kazuki Nakajima.

LMP2

A relentless Nicolas Lapierre helped KCMG cement a 1m40s lead in LMP2.

Lapierre started the hour with a two-minute lead, but despite making a pair of pitstops to the one of its rivals, the KCMG car only lost 20 seconds, with Matt Howson now behind the wheel.

Greaves Motorsport had been KCMG's closest challenger, but Gary Hirsch stopped at the Esses with a flat battery and was last seen undertaking trackside repairs. The car has lost 14 laps and is now 18th in the class.

TDS Racing and Murphy Prototypes sit second and third, although Pierre Thiriet and Mark Patterson are split by approximately 1m30s.

Vincent Capillaire is now in the fourth-placed Signatech Alpine, while Sam Bird is back behind the wheel of the #26 G-Drive (OAK) Ligier and has moved from seventh to fifth.

The hopes of OAK Racing's Honda-powered entry took a blow when Chris Cumming spun at Indianapolis late in the hour, dropping from seventh to 11th.

GTE

Aston Martin Racing moved back into the lead of both the GTE Pro and GTE Am battles.

Fernando Rees's third consecutive stint helped lift the #99 Vantage ahead of the Chevrolet Corvette C7.R, which stopped for tyres and to swap Tommy Milner with Jordan Taylor.

That dropped it to third in GTE, but Taylor soon caught Darren Turner's triple-stinting 97 Aston and moved back into second, though remained more than 20s off the lead at the quarter-distance mark.

Porsche moved into fourth place as Olivier Beretta's lack of pace cost the #71 AF Corse Ferrari a position, while the #51 Ferrari remains two minutes adrift of the sister car after earlier woes.

AMR's #98 Am-class Vantage took back the lead from the #72 SMP Ferrari, though that battle continues to rage as the two are out of sync in terms of pit strategy.

The #83 AF Corse Ferrari has moved into third after the #77 Proton Porsche slipped back.
