Lewis Hamilton and Nico Rosberg collided at Les Combes on lap two which compromised the race of both drivers and left Hamilton point-less.
Wolff said the collision “ultimately cost us a one-two finish today, because we saw that our car had that kind of performance in it”.
“It has been our clear policy to let the drivers race this year but rule number one is: don’t hit each other. To see that kind of contact, so early in the race, is an unacceptable level of risk to be taking out on track.
“It cannot – and will not – happen again.”
Rosberg eventually finished second, pitting three times after locking up and damaging his tyres while racing Sebastian Vettel.
“After the collision, Nico drove the first stint with a significantly damaged front wing, changed it, then had to make an additional stop after flat-spotting his left front tyre to the point where it was dangerous,” Wolff explained. “He then charged back through the field and was impressively close to taking the win in spite of a dramatic race.”
Hamilton ran at the tail of the field with a badly damaged car and urged his team to retire the car to save its engine. They did so six laps from home.
“Lewis was fighting with one hand tied behind his back after the puncture, which damaged the floor and cost him a significant amount of performance,” said Wolff.
“We left him out there in case the Safety Car came out, bunched up the field and allow us to gain some places, but it became clear that he had lost too much performance and was continuing to do so, so we retired the car before the finish.”
