Sebastian Vettel may have topped the timesheet on the final day of Formula 1 pre-season testing, but Mercedes claimed the day four headlines.
After two weeks of disciplined data gathering, Lewis Hamilton and Valtteri Bottas unlocked performance from the W10, ending up second and third on the timesheet – Hamilton just 0.003s adrift of Vettel’s benchmark.
Here is a round-up of all the main storylines from the final day of pre-season testing.
McLaren rookie Lando Norris was fastest on the first day of the second Formula 1 pre-season test at the Circuit de Barcelona, despite finding reliability issues.
Equipped with the C5 tyres – the softest compound in Pirelli’s range – Norris posted a 1m17.709s time to edge Red Bull’s Pierre Gasly off of top spot.
Soon after vaulting to the top of the times, Norris stopped on track for the second time in the day. The first was caused by a hydraulic problem on the MCL34 before lunch.
Both Ferrari and Mercedes’ mileage was hampered, as the Scuderia completed cooling checks in the morning, while Valtteri Bottas stopped on track with an oil pressure problem after just one lap at the start of the afternoon session.
Here is a full round up of how all 10 teams fared on the first day of the second test.
