While some useful information and data was gathered on Tuesday, it wasn't the smoothest day of running for the team.
"It wasn't the best of days for us as we only completed 49 laps," explained Trackside Engineering Director, Andrew Shovlin.
"We had an issue with the gearbox early on that cost us some time. We were able to tick off some of the data collection test items in the remainder of the morning and early afternoon but, just as we started to get into some proper running, it began to rain.
"It's been good to see George back in the car today and he's done a good job but we had hoped to keep him a bit busier.
"We've got a lot to do tomorrow, and it looks like we may get some more rain, so we will review our programme tonight to make sure we can make the most of these conditions."
