Felipe Massa says a rear wing stall caused his crash during second practice for the Chinese Grand Prix.
Massa was 10th in the morning session, but spun and crashed at the chicane at Turn 14 in the afternoon as he attempted to complete a flying lap in the FW37.
The Brazilian clipped the wall, damaging his front wing, and prompting a brief red flag period as his car was cleared.
“The first session went to plan, but this afternoon we had a few issues with the rear wing,” said Massa.
“Under braking I lost all grip in the rear tyres and as a result the car spun which put me out for the rest of the session.”
Valtteri Bottas ended the day seventh in the sister Williams, and was impressed with the latest developments the team has brought to the car in Shanghai.
“The updates we brought have worked, so we are a little quicker through the corners now, which is always positive,” he explained.
“The temperature here suits us better than in Malaysia, so I think we can be strong in qualifying but we need to make sure we focus on the race and especially on the front left tyre graining.”
