Felipe Nasr and Susie Wolff both ended Thursday’s test session with red faces after the pair collided at Turn Five, causing substantial damage to both cars.
Both had enjoyed good mornings with Wolff completing 83 laps for Williams, whilst Nasr showed impressive pace. However the afternoon didn’t go so smoothly.
The crash brought out the red flag and an almost 20-minute delay whilst the track was cleared of both cars and the resultant debris.
A Williams spokesperson believes Nasr was to blame as the Brazilian took a wide line to pass Wolff, who was on an outlap, before cutting across at high-speed damaging the rear of the C34 and the front of the FW37.
Sauber have yet to comment on the incident and both drivers are expected to remain in the garage for the rest of the day whilst the damage is assessed.
