Valtteri Bottas set the fastest lap time on the final day of Formula One testing on Friday, as Mercedes maintained its status of title favorite heading toward the new season.

Red Bull's Max Verstappen and Renault's Daniel Ricciardo were right behind the Finnish driver within one tenth of a second on the Barcelona-Catalunya Circuit.

Last week, Bottas recorded the fastest time of any driver in the six-day preseason.
