Summary In his accident, Hamilton lost control and was unable to stop his car sliding into the wall
Montreal (AFP) - Lewis Hamilton topped the times and then crashed into the barriers in his Mercedes car in heavy rain that curtailed Friday s second practice for Sunday s Canadian Grand Prix.
Two 30-year-old Briton, a two-time world champion, had topped the times in Friday morning s opening free practice session ahead of his Mercedes team-mate Nico Rosberg and the pair were more than 1.5 seconds clear of the field.
In his accident, Hamilton lost control and was unable to stop his car sliding into the wall at the tight and tricky track that has a record for accidents and incidents.
"It has still been a good day so I am pretty relaxed," said Hamilton. "It wasn t my call to go out. Not necessarily, no. It was just like being on ice! It was so slippery.
"We collectively don t think it was the best call to go out, but at the end of the day it didn t affect our running."
Mercedes technical chief Paddy Lowe admitted: "It didn t quite end the way we wanted it to. We went out to do practice race starts, a normal part of our P2 programme. Unfortunately, the worsened quicker than expected and caught Lewis out."
Mercedes team boss Toto Wolff added: "I think he just aquaplaned. The front wing is gone, but hopefully no more.
"He was pretty quick. He s fastest on the time-sheets, but I won t read too much into it. It s just one of those days, one of those Fridays when it is difficult to get a lap together."
Hamilton was fastest ahead of four-time champion Sebastian Vettel and his Ferrari team-mate Kimi Raikkonen at the time of the accident with Rosberg back in fourth.
"The car s feeling good out there, really good," he said of his Mercedes. "But Ferrari have picked up the pace with their engine, which will be interesting to see tomorrow. I think we are still in good form."
