Collective testing at the Circuit de Catalunya saw Kevin Magnussen once again dominating over the course of the Friday as he prepares for the title decider.
The championship leader topped the time sheet in the first session and his DAMS model was followed closely by Sergey Sirotkin. The Russian is widely tipped to become Sauber F1 driver next year. The two were separated by six-hundredths-of-a-second as the cars rushed to post their final times.
Norman Nato and title challenger, Stoffel Vandoorne, were close in third and fourth respectively as the flag dropped on the session.
The glaring sun of Barcelona saw little incident at the circuit however the variation in tyre wear caused by the heat, initially, saw drastic changes in the standings come the second collective test. Fortec Motorsport's, Oliver Webb, was top of the time sheets by lap 17 on an open track. Just one tenth separated him and his compatriot, William Buller.
Despite the best efforts of his rivals, Kevin Magnussen once again set the pace. He was followed by Will Stevens, Vandoorne and Arden Caterham's Antonio Felix da Costa.
Fortec Motorsports and DAMS will also be competing for the constructor's title. A win from Kevin Magnussen would secure victory for DAMS.
Jazeman Jaafar was not present at either practice session after contracting an infection. It is unknown whether he will be racing this weekend, at this time.
