Hamilton fastest in testing as McLaren struggle

Hamilton fastest in testing as McLaren struggle

Bahrain victor Sebastian Vettel was second fastest as he resumed normal Ferrari duties following a day of Pirelli tyre testing on Tuesday, though it was far from a trouble-free session for the Prancing Horse.

Bottas spent his day focused on both aerodynamic work and better understanding of tyres, with Mercedes having made clear it was trying to crack its recent struggle with long-run form this week.

"We need to improve the vehicle and our knowledge about the tyres so that we are in a better position in the next race", he is quoted by the DPA news agency.

Mechanical issues meant that Vettel was able to complete just eight laps before lunch, with further issues in the afternoon limiting the German to a total of 64 for the day. The problem was quickly resolved once the auto was returned to the pits and Bottas continued to rack up the laps throughout the afternoon, with a best time of 1:31.280. That led to an extended period of downtime in the garage as the team conducted a series of systems checks, but the auto reappeared in the early afternoon. Stoffel Vandoorne was fourth fastest for McLaren-Honda following a much more promising day in which his best lap was just 0.828s off Bottas.

Gary Paffett returned to an official Formula One test for the first time since 2013 and racked up 59 laps in the Williams during the morning.

It was the second time the part has fallen off Bottas's vehicle, following a similar incident in China last weekend.

Russian 21-year-old Sergey Sirotkin was at the wheel with the Renault and completed 90 laps in his new role as the team's test driver.

Ferrari's challenge is slightly different from Mercedes, in that Vettel's team is on top of its race performance but has proved lacking on single-lap pace.
