Susie Wolff couldn't hide her frustration at missing out on the opportunity to push on in the Williams FW37 after a tangle with Felipe Nasr ended her day in the car early.

Wolff was given a full day in the Mercedes-powered car and tasked with working on longer runs in the morning, the Williams Martini Racing driver completing almost 80 laps prior to the lunchtime break.

However, her day would come to an abrupt conclusion when she involved in a collision with Felipe Nasr, the Brazilian - who was on a fast lap - clipping a slower moving Wolff's front-left with his right-rear as he came across to take the line into turn five.

Causing damage to both cars, with a further technical issue stopping her when she emerged on track later on, Wolff was disappointed her limited time in the car was curtailed, particularly as she had planned to go for faster timed runs in the afternoon.

"In the morning I had a race simulation and then in the afternoon I was going to do more performance runs, which for me would have been the highlight of the day.

"Time in the car is the best bit of my job because time in an F1 car is so limited, so for me to lose so much time in the afternoon is really tough, but it happened and you've got to keep your head up.

Despite the early finish, Wolff was pleased with her time in the car and was impressed with the progress made to the FW37 over the FW36.

"I drove the FW36 last in July last year so there was already quite a lot of improvements to the last race in Abu Dhabi, but for me we have made improvements under braking and stability, and the balance feels good. There is an improvement in the power unit in terms of driveability. Ultimately we are going to see in qualifying at Melbourne where we are from everyone else.

Wolff says she won't get another run in the car during pre-season testing, but will return later in the year.
