We covered the work we needed to do during first practice and, although the session was slightly disrupted by light rain showers, we managed to run the car at both high and low fuel levels. This is a great circuit and, as expected, is proving hard on brakes; similarly, the effective loss of downforce experienced from running at altitude meant lots of drivers were struggling to put together consistent laps. Nico and Lewis were both happy with the car today and able to set competitive times. Nico suffered a problem with the ERS system in P1 which we were able to fix for the afternoon. We then had to cut Lewis’ afternoon session slightly short as a precaution after he experienced a different ERS issue. The weather forecast predicts dry conditions across the rest of the weekend, so we will be working tonight to prepare the cars accordingly for tomorrow and Sunday.
