Toyota’s lead in the Le Mans 24 Hours grew to its biggest margin yet during the 10th hour of the race.

After Marcel Fassler and Marc Gene pushed hard during their stints to keep the leading Toyota of Alexander Wurz on its toes, driver changes in both Audis allowed Wurz to extend his lead during the most recent round of stops.

Andre Lotterer took over the second-placed #2 car, while Tom Kristensen replaced Gene in the #1.

Behind the Audis, the two Porsche 919 Hybrids continued to circulate in the top five, Mark Webber opening his Le Mans account with a quadruple stint before handing back to Timo Bernhard.

Alex Brundle leads the LMP2 class having taken over the #35 G-Drive-backed OAK Ligier from Jann Mardenborough, who gradually built up the car’s lead during a strong series of stints.

Nelson Panciatici runs second in the #36 Signatech Alpine ORECA, with the #34 Race Performance ORECA third in what is proving to be a tense battle behind the leader.

The #46 TDS Ligier has run strongly in the top four, but was forced to serve a 35-second stop/go penalty for speeding in the pits.

But while OAK is enjoying success with its Ligier, the #26 OAK-run G-Drive Morgan is now over 20 laps down having stopped out on track.

Aston Martin still leads both GTE classes, but it is a different Vantage at the head of the Am division after the long-time leader hit mechanical problems.

In the Pro element, Stefan Mucke fought off a mid-hour charge from Gianmaria Bruni to maintain a comfortable advantage, with Tommy Milner’s Corvette assuming the role of chief pusuer when Bruni pit early and Tony Vilander took over.

They swapped positions at the end of the hour when Milner pit, but Mucke continued to hold a huge, if slightly misleading, gap of a minute and a half.

It’s the #95 Aston that leads the GTE Am clas, with Kristian Poulsen now heading the #72 SMP Ferrari after the #98 Aston Martin, which had led since the third hour, developed a power steering issue.
