Button focuses on tyre evaluations
The most consistent weather conditions of the entire test allowed Jenson and the team to power through a tyre compound evaluation programme, balancing aero and mechanical set-ups to the different types of tyre.
In the morning, Jenson completed a number of shorter runs on three separate tyre compounds, evaluating set-ups before switching to longer runs in the afternoon, with a view to evaluating their durability.
Following his third test with the Vodafone McLaren Mercedes team, Jenson reported that he feels very comfortable and confident in the car.
The team decamps to Barcelona next week for the fourth and final test of the winter. Both drivers will spend alternate days in the car evaluating the new bodywork and aerodynamic components ahead of the season-opener in Bahrain on March 14.
