Mercedes ominously dominant in first pre-season test
Mercedes ended the first pre-season Formula 1 test with a dominant one-two finish.
Valtteri Bottas, in particular, posted an eye-catching fastest lap on the final day on Friday at Barcelona's Circuit de Catalunya as Mercedes laid down a marker in their bid for seven consecutive titles.
Although Bottas used the softest of the five compounds made available by Pirelli for testing with the C5, he offered a hint of the speed potential of his Mercedes W11 with a lap of one minute 15.732secs.
In context, the lap was half-a-second quicker than in testing at the track a year ago, and only three-tenths of a second behind the lap record he set with his pole position time of 1:15.406s in qualifying for last season's Spanish Grand Prix.
Bottas' time was further impressive as team-mate Lewis Hamilton finished 0.784s adrift on the same tyre.
The quartet was covered by 0.667s, with Ocon 1.370s adrift of Bottas. Giovinazzi, meanwhile covered a day-high 152 laps, with Stroll the only other driver to clock up over a century of laps for the day with 116.
The best of the rest was headed by Renault's Daniel Ricciardo, who stopped on track at one stage during his afternoon run, but still managed 93 laps, with his best a 1:17.574s on C3 medium tyres.
Max Verstappen then led another quartet of drivers on the C4 hard compound, racking up 86 laps during his morning stint to finish almost two seconds behind Bottas in his Red Bull.
After his minor accident late in the afternoon on Thursday, Haas' Romain Grosjean completed 48 laps on Friday, but was 2.648s behind Bottas on medium tyres.
After a power unit issue curtailed his morning session to 94 minutes and 40 laps, Ferrari's Sebastian Vettel added a further 60 in the afternoon following an engine change, with the four-time champion 2.652s down on the mediums.
McLaren's Lando Norris was 14th, with Williams rookie Nicolas Latifi 3.272s back, with both on mediums.
Following an issue late in the morning session that saw Latifi stop on track with wisps of smoke emerging from the FW43, he only managed an additional 29 laps in the afternoon.
It was a sorry day for Kevin Magnussen as he clipped a wall after sliding off track in his Haas, an incident that ended his running for the day after just four laps.
