Hamilton refused to blame Sutil for the incident that cost the Force India driver a three-place penalty, demoting the German to 17th as punishment for impeding the British driver as he tried to set a timed lap.
"I just didn't get a lap together in Q2 today and it's hugely disappointing, not just for me, but also for the team and I can only apologize to them as we had a quick car today," said the 2008 world champion, who won the race last year while at McLaren.
"I came off at Parabolica on my first run which damaged the car and it was a downward spiral from there really."
Daniel Ricciardo, who will replace his fellow Australian Webber at Red Bull next season, bounced back from a difficult Friday by qualifying seventh for Toro Rosso -- his teammate Jean Eric Vergne was 10th.
McLaren's struggles continued, with Sergio Perez eighth and 2009 world champion Jenson Button ninth.
Kimi Raikkonen's title hopes receded even further as the Finn was back in 11th for Lotus, with teammate Romain Grosjean 13th.
