Williams bounced back from a troublesome first week of Formula 1 pre-season running in Barcelona to top the opening day of the second test on Tuesday through Felipe Massa.
Williams was forced to end running early on two days last week and skipped Thursday altogether due to damage sustained in crashes involving 18-year-old rookie Lance Stroll.
Massa was handed the opening day of the second test in a bid to maximize track-time, and the Brazilian duly delivered by racking up over 160 laps, one of which proved to be the fastest of the day.
A best time of 1:19.726 saw Massa flirt with the fastest overall time in testing, set last week by Mercedes’ Valtteri Bottas, while Red Bull’s Daniel Ricciardo finished second, two-tenths of a second behind.
Ricciardo’s lap was a first sign of raw one-lap pace from Red Bull, which opted to spend all of last week focusing on reliability.
Sebastian Vettel continued Ferrari’s impressive start to testing by finishing third, as well as completing more laps than any other driver. The German was just six-thousandths of a second shy of Ricciardo’s time.
Mercedes split its running between Lewis Hamilton and Bottas once again on Tuesday, taking the morning and afternoon sessions respectively. Hamilton was unhappy with his morning running, with the team ending its program early so it could make changes to the car. The Briton ended up fourth-fastest ahead of Bottas in P5.
Esteban Ocon was sixth for Force India ahead of Renault’s Nico Hulkenberg, the latter splitting running with teammate Jolyon Palmer. Kevin Magnussen was eighth in the Haas VF-17, while Toro Rosso bounced back after a tough first week with Daniil Kvyat winding up P9.
McLaren’s nightmare start to pre-season testing continued as Stoffel Vandoorne’s running was once again interrupted by an engine issue, forcing Honda into changing the power unit on his car over lunch. The Belgian completed just half the mileage of the pace-setters and ended the day 10th.
Sauber split its running between Pascal Wehrlein and Marcus Ericsson, the former making his first appearance in the C36 car after missing the opening test through injury. They finished 11th and 12th ahead of Renault’s Palmer, who propped up the timesheets.
