The defending four-times champion, who increased his lead in this year's title race to 17 points ahead of Sebastian Vettel of Ferrari, added that he and the Mercedes team were still uncertain about the races ahead.
Lewis Hamilton said he would sleep "like a baby" on Sunday after claiming another of Michael Schumacher's Formula One records with a 64th win that felt as special as any.
Vettel put their drop in form down to three things: speed, tyres - referring to the change in tread depth for this specific race - and reliability.
"A 1-2 for the team", Hamilton said.
"The best ones are very sensitive and fragile", Wolff said. "We came to Melbourne and our vehicle performed well and suddenly you are behind a Ferrari".
The race leader had to navigate multiple virtual safety auto periods during the race, as well as a full safety vehicle deployed for an opening lap crash caused by Romain Grosjean who had spun in Turn 3. Therefore we were not able to stay out for another 23 laps.
"Not every race feels as great as that one does".
Wolff added that Hamilton's triumph would fix some of the damage done by his recent loss of form and confidence.
"Sebastian's front left was really bad, they needed to pit, and we were a little bit anxious that structurally we could have a failure, so that's why we chose to pit Lewis as well", said Wolff. "Now, it's important that we continue to push hard".
"It was definitely the closest it's been to some of the performances we had past year". Even at the end I was not in healthy shape with the tyres despite the fact mine were the newest.
By this point, Vettel had gotten ahead of Bottas for scond place and was hoping to chase after Lewis Hamilton who had maintained his lead from pole position. He did not look able to threaten Hamilton however, with Mercedes optimistic that they are getting to grips wth the issue of the tyre operating window.
The Spanish Grand Prix takes place Sunday at 9AM ET from Circuit de Barcelona-Catalunya.
"I was told by the team to stop the vehicle", Raikkonen said".
Ferrari pitted Vettel early from second, forcing Mercedes to react with Bottas a couple of laps later.
The red lights' exodus saw the red vehicle of Sebastian Vettel push past Mercedes' Valtteri Bottas into the first corner, staggering the Mercedes-Ferrari running order.
Mercedes held firm to their one-stop plan.
Out came the safety auto with Hamilton then executing a masterful restart to leave Vettel for dust before establishing a comfortable cushion over his rival.
Wolff sympathised with his rivals at the Scuderia.
"We do after the five races now have a much, much better understanding of the auto, of what we need to do to get the vehicle to be working - but we still have learning to do, improvements to be made". "Ferrari did the opposite". I think that showed in my face [as he celebrated after winning]. Bottas was soon going fastest before Hamilton topped the times after half an hour.
Could anyone else have done more in this race?
