Felipe Massa says "the DRS was almost 100% open" when he hit the brakes for Turn 1 in FP1 for the Canadian Grand Prix which led to his heavy crash.
Half an hour into the opening session, Massa lost control under braking for Turn 1 and slid on the grass before spinning and hitting the tyre wall backwards. Williams later confirmed a DRS problem was to blame and Massa says the system was nearly fully open on a new rear wing despite his attempts to close it.
“The accident was nothing to do with me, it was a problem with the rear wing, the DRS," Massa said. "When I braked I even switched it off myself before the braking zone, but it didn’t close so when I braked the DRS was almost 100% open and I had no grip on the rear so that is why I crashed.
"So it was also the first time we tried this rear wing so we are analysing what actually happened. It’s a shame because crashing like that at the beginning of the day is definitely a pain for everybody, for the team, for me as well.
"The afternoon was OK, for sure I didn’t have everything we can have in the car for the performance in the afternoon because of the crash so I am really looking forward that tomorrow everything will be in the car and we can be competitive. The car showed reasonably good pace straight away so I think that’s positive and I hope it can be even more positive for tomorrow.”
And Massa says Williams needs to investigate the problem thoroughly as it is not the first time the team has had DRS trouble.
“We had already, I think I had once and Valtteri [Bottas] had it another time maybe last year. So it’s not the first time but unfortunately I had it here and we need to analyse and not repeat, definitely.”
