This is the first day of testing for Scuderia Ferrari and six other Formula 1 teams here at the Spanish circuit.
This morning, the SF15-T was the first car to take to the track, with Sebastian Vettel making his debut at the wheel of the new car. He completed 9 laps, the quickest in 1.25.764.
System checks were the main items on the programme which was altered mid-morning, to improve the radio communications between team and driver.
The decision was therefore taken to bring forward the lunch break, so as to resume the planned programme for the afternoon.
