Ullrich: Risky tyre strategy right call

Audi Sport boss Dr Wolfgang Ullrich has described the thinking behind the risky tyre strategy which ultimately enabled the marque to claim its 10th Le Mans win

Ullrich: Risky tyre strategy right call

The victorious #2 Audi was tasked with doing two unprecedented five stint runs on a single set of tyres, which was deemed a necessary tactic to reduce its total pitstop time while Peugeot's chasing 908s were able to do at least one extra lap per stint.

"Our Peugeot rivals were as strong as ever, with four cars against us," said Ullrich. "I had to ask our drivers to do something very difficult - to go as fast as they could but take no risks.

"We knew from testing that we could do five stints on one set of tyres, and it was that strategy that enabled us to succeed. We asked a lot of our drivers. We knew that Peugeot would be able to do an extra lap so we had to take the risk. The Peugeot drivers did their jobs perfectly."

The strategy was neary undone less than an hour from the flag when Andre Lotterer picked up a puncture and the team was forced to do another stop earlier than planned, leaving the #2 Audi exposed to Simon Pagenaud's charging Peugeot.

"We had a left-rear puncture, which was why we had to stop and change tyres when we did [in the last hour]. We were very close to our fuel window - very close. Another lap and we would not have finished the race."

Inside the Le Mans finish too barmy for Hollywood

It could've been even better had the race been one lap shorter, when its cars ran 1-2, but the stranger-than-fiction reality has spurred the team to reach greater heights

OPINION: With four of the five Hypercar entries unproven in a 24-hour race, it would not have been unexpected for at least one of them to suffer serious reliability trouble. That they all managed to make it through the race relatively unscathed, says GARY WATKINS, was something of a surprise.

How overlooked Mazda produced one of Le Mans' greatest shocks

The screaming rotary-engined Mazda 787 is regarded as one of the most popular Le Mans 24 Hours-winning cars, but until its surprise success on this day 30 years ago it was never regarded as a likely victor. But that reckoned without a new technical partner, some canny political manoeuvring and a rival's bizarre self-inflicted weakness
