Alex Lynn says Felipe Massa will do more work with the radical Williams rear wing on on Wednesday during testing in Barcelona.
Williams ran a striking rear wing on Tuesday morning which featured additional winglets above the normal set-up in an attempt to simulate increased downforce levels. The team explained the wing was being used "to gain a better understanding of the car aero balance over a lap", and development driver Lynn says he had to gain data with it before Massa tests performance.
"It did a lot more than it looked so it’s difficult for me to say," Lynn said when asked if he noticed a difference. "I wasn’t pushing that hard, the only laps I pushed were the end of the morning really on the medium tyre so it was a bit about getting aero scans for it and straight line speed stuff.
"It was a bit of a shame as it looked like it would have given some good downforce, but I wasn’t quite able to do anything on it.
"I didn’t push that hard on it, I wasn’t allowed to. You’ll probably see Felipe do a bit more on it tomorrow. He’ll be the better one to ask tomorrow."
And Lynn was pleased with his own performance on his first outing in the FW38, despite a slightly early finish.
"We finished early but still with loads of laps, we have mainly been engine mileage limited but I think that’s more the good work of the team turning things round in time. I don’t expect much else from a team like Williams.
"I gave a good account of myself considering the runs I was given and what the programme was so hopefully the team will give some good feedback."
