Hamilton was a comfortable winner of the Red Bull Ring race following a stunning lap in the wet in qualifying landed him pole, while Valtteri Bottas passed Max Verstappen in the closing stages to finish behind his team-mate for a one-two.
Given the gearbox problems which disrupted their race last week, Wolff couldn't have been happier with the outcome, particularly the display of Hamilton, telling Sky Sports F1: "I think we can be very satisfied with this weekend. A tremendous job from everybody and also to getting our worries from last week under control.
"I think everything has been said about Lewis' talent and abilities. Sometimes he needs - and all of us - needs weekends like the last one where you just work very hard to recover and when he is in that space, he is just unbeatable.
"I have never seen anything like this in the top class of motor racing. It is like seeing a unicorn. That was exceptional."

"Hungary is a great track, totally different to what we have in Spielberg so it will be really interesting to benchmark ourselves there."
