Nico Rosberg voiced his dismay over how his qualifying session for the Canadian Grand Prix went wrong just when it mattered, which eased title rival Lewis Hamilton’s path to pole position.
Rosberg outpaced Hamilton on soft tyres in Q1 around Montreal, and was right on his pace in Q2 on the supersofts. But then a mystery problem struck, losing his vital rear-end grip in the Q3 pole position shootout.
"Everything was going really well, I felt comfortable in attacking, and then everything went really wrong in Q3," said Rosberg.
"I just had less rear grip, the team thinks it knows why, but we need to analyse it.
"It is really disappointing – just completely lost it there. There wasn't any major changes [between Q2 and Q3] we just lost a lot of rear grip.
"The first lap in Q3 was really good, actually, but the laptime was nowhere. It just went wrong, in the end. That sucks."
Rosberg has promised to bounce back in the race tomorrow, as he bids to close the 10-point gap between himself and Hamilton.
He added: "It is disappointing, but fair play to Lewis, and the race is tomorrow – so good chances and here you can overtake so it's not over yet."
