Ferrari were fastest for the second time in four days on Thursday at the end of the first four-day pre-season test ahead of the 2017 Formula 1® Rolex Australian Grand Prix at Albert Park.
Finn Kimi Raikkonen wound up eight-tenths quicker than Dutchman Max Verstappen of Red Bull while Lewis Hamilton did not run in his new Mercedes due to an electrical problem.
Hopes that the new ‘fatter and faster’ cars might turn in lap times that made them the fastest of all time were thwarted as the final day was used, in part, for wet weather testing for Pirelli.
Hamilton’s new team-mate Finn Valtteri Bottas, who has replaced retired 2016 champion German Nico Rosberg, was eighth fastest.
On a somewhat chaotic day, the Williams team were also unable to run following 18-year-old Canadian rookie Lance Stroll’s crash on Wednesday.
Williams said they "aimed to be back on track" for the start of the second and final four-day test starting on Tuesday.
