Romain Grosjean was fastest for Lotus on a dramatic fourth and final day of testing in Barcelona.
Grosjean set the pace with a lap of 1:24.067 – the best time of the week – set on the super-soft tyre, to ensure Lotus topped three of the four days of running in Barcelona.
However, the Frenchman’s time was overshadowed by an accident for Fernando Alonso, on what was a windy day interrupted by red flags.
Nico Rosberg completed 131 laps, the most of any driver on the day, on route to second fastest for Mercedes, setting his best time on the medium compound Pirellis, just two tenths shy of Grosjean’s test topping lap.
Daniil Kvyat was third for Red Bull, ahead of Felipe Nasr, who managed 73 laps in the Sauber, in spite of missing almost the entirety of the morning session due to a ‘general issues’.
Valtteri Bottas racked up 129 laps at the wheel of the Williams FW37, just two short go Nico Rosberg’s top total for the day, despite stopping out on track in the afternoon – a first for Williams during testing year.
The Finn spent most of the day running on the medium tyre, but improved late in the afternoon on a soft tyre run to end the day fifth fastest.
The Spaniard slumped to sixth in the standings by the close of running, but ended the day seven tenths of a second clear of Sebastian Vettel in the Ferrari.
Nico Hulkenberg managed just 36 laps on his one and only day of testing this week with Force India, before a power unit issue forced him to stop out on track, ending his afternoon.
Alonso propped up the timesheets in the McLaren after his early crash, with 20 laps on the board.
Jenson Button was scheduled to take over from his team-mate the MP4-30, but McLaren opted to cut short its programme after the lunchtime break.
Testing resumes at the Spanish circuit on Thursday.
