Initial forecasts had suggested there would be a 30% chance of rain at the Tuscan track, but damp conditions in the early morning led the team to run a re-worked plan, which included some running on Pirelli's intermediate tires. The Team used those outings to test a number of aerodynamic and mechanical development parts, which had been brought to Italy for the test.
A brief lull in the wet weather later in the morning gave Mark a couple of dry tire runs and the team maximized the opportunity before the heaviest rain of the day arrived. During that spell, Mark set the day's second quickest time, recording a lap of 1.23:648
Mark commented: "Obviously, the weather wasn't great today, so we didn't get to do much running in the dry. Really, we only got one decent run on the slicks. Then it rained after lunch and with limited sets of wets available, you can't do that much. We're hoping for better over the next couple of days.
"It's an important test. We have a lot of information to gather and, while today didn't quite work out as expected, I'm optimistic that over the course of the next few days we'll get the information we need.
"I have to say this is a fantastic track. It's very challenging for the driver and very quick. I don't know if we'll ever race here in the future, you never know, but to see the crowd here today was very special. A lot of people came to watch and that's great."
