Sebastian was the fastest of our two drivers during this morning's first Free Practice session of the USA Grand Prix. He topped the time sheets with 1:38.125 after thirty laps of the Circuit of the Americas track here in Austin, Texas.
Mark was fifth-fastest with 1:40.650, also after thirty laps.
There's now a quick turnaround and vast amounts of information for the team to absorb and process from the new circuit before FP2 begins at 1pm local time.
