F1 pre-season testing comes to a close in Bahrain on Saturday, a week before the first qualifying session of the year gets underway.
Kevin Magnussen finished Friday fastest for Haas after going three-tenths of a second faster than Ferrari's Carlos Sainz during the team's extra hour of allocated running in an attempt to catch up on time lost during Thursday morning.
The three-day event is the final chance for teams to hone in on optimum configurations ahead of the first race of the year at the same venue next weekend.
