Lewis Hamilton defied all of the expected norms by setting the fastest lap with 32 lap-old tyres, according to Mercedes boss Wolff.
The British driver had seemingly already won the race when he set the record in the very last lap.
Mercedes team-mate Valtteri Bottas was holding the fastest lap record, but was beaten to the extra point by 0.037s.
Hamilton’s team suggested that he pulled into the pitstop for fresh tyres toward the end of the race, so that he could try and set the fastest lap.
But the Brit defied orders because he was worried that Bottas would catch him up.
He was comfortable seeing out the British Grand Prix, before putting his foot down on the final lap.
Hamilton’s ability to set the fastest lap, when he’d already been on his hard tyres for 31 laps, made the team look silly, claimed Wolff.
“First of all, on the fastest lap with the 32-old hard tyres, very surprising,” Wolff told Autosport.
“And we tend to have a laugh because the engineers have that new presentation in our Sunday morning meeting which basically says ‘you don’t need to go for fastest lap, it doesn’t make any sense anyway’.
“And then he pulls one out like this.
“Which makes all the data look a little bit silly. But it’s just his ability.”
Bottas cruised to second place at Silverstone. He blamed his car losing battery for failing to set the fastest lap.
“I tried pretty hard, but I didn’t really have full battery level at that moment,” he said.
“It’s something we actually raised in the meeting, that can be a lot better in the race if we really have some margin to go for the fastest lap, to charge the pack more, to really deploy more. So I feel I lost a bit there.”
Hamilton leads the Drivers’ Championship by 39 points at the half-way stage, with Bottas in second and well clear of third-placed Max Verstappen.
The next race is scheduled to take place next weekend in Germany, with Hamilton the odds-on favourite to claim victory once more.
