Daniel Ricciardo set the fastest time on the opening day of Pirelli's wet weather test at Paul Ricard on Monday.
The two-day test is the first F1 action of 2016 and is taking place to allow Pirelli time to develop its wet-weather tyre ahead of the 2016 season. Three teams are present, with Ricciardo and Red Bull topping the times on the opening day ahead of Stoffel Vandoorne's McLaren and Kimi Raikkonen's Ferrari. The teams are running 2015-specification cars and are not allowed to test new parts.
The drivers conducted 10-lap runs with the cars leaving the pits at 10 second intervals in order to maintain consistent conditions. Trackside sprinklers were turned on between runs to keep the track wet and provide the optimum conditions for Pirelli to gather data. Both 2015-spec and prototype wet tyres were used, but details of the new-spec tyres were not communicated with the teams.
The three cars completed 285 laps in total, with Ricciardo and Raikkonen both racking up 99 laps while Vandoorne's McLaren stopped short at 87 laps due to a technical problem. The session ended an hour early once Pirelli had completed its planned mileage, with another day of testing scheduled for Tuesday.
Vandoorne will be joined by Sebastian Vettel (Ferrari) and Daniil Kvyat (Red Bull) on the second day of the wet weather test on Tuesday.
