Rosberg took his fourth consecutive pole, ahead of his Mercedes team-mate Hamilton, Vettel qualified third in Mexico but admitted he expected to be closer to the Mercedes team than he actually was in qualifying.
Hamilton successfully overtook Rosberg at the turn one of two of the last three races and the Brits sound confident of again attacks this weekend.
When the media, asked if the Mercedes duo would talk about the start ahead of Sunday’s race, Rosberg said: “It’s no different, you know.
“It is always going to be a battle and what’s in the past is in the past and now we move forward, it doesn’t change.”
Newly crowned triple time world champion, Lewis Hamilton, sitting alongside his team-mate, and who is now on a five-race streak without securing pole, added: “The same as he’s just said.”
The four-time world champion, Vettel joked: “Can you make sure you take both of you out so I can go through? Yes? No? I tried.”
Neither Rosberg nor Hamilton responded to Vettel’s jibe.
“We were hoping for it to be a bit closer but in the end it wasn’t,” said Vettel.
“I tried everything. I was very happy with the first attempt in Q3. On the second one I probably pushing too hard and I didn’t go any faster.
“In the end they were just a sniff too quick. But who knows what happens tomorrow.”
