Driver Jenson Button
Location Circuit de Barcelona-Catalunya (4.655km)
Best lap-time 1m31.479s
The day kicked off with Jenson conducting some aerodynamic tests, which meant he only completed a single timed lap.
After just seven laps, Jenson noted a vibration and brought the car back to the pits, where we discovered a hydraulic leak that required a full power-unit change. The time required to complete the change unfortunately meant that our running for the day was over before lunchtime.
