Martin Sander, former director of Audi UK and now senior director of sales for Audi USA, appears quietly confident though.
"The Porsches and Toyotas are very fast. But it's rare to see that kind of pace maintained for the duration of the whole event," he says. "It's not uncommon to see some contenders start out very fast but the performance soon tails off."
Sander adds: "The Peugeots were quick. During one race I mentioned this to Dr Wolfgang Ullrich, head of Audi Sport. He looked at me, then just calmly responded that they could not maintain this pace. Come the next morning, they had all retired."
Porsche is putting on a strong show though, with its cars appearing to clock up more fast laps in single stints than its Audi rivals.
As the old adage goes, 'to finish first, first you have to finish'. Slow and steady can win the race. Well, moderately quick and steady, at least.
