F1 testing continues in Barcelona on Saturday with the penultimate day of running at the Circuit de Catalunya.
The likes of Mark Webber,
Lewis Hamilton and
Felipe Massa return to action having been on track on Thursday for what will be their final day of running before the teams head to Albert Park for the opening race of the year.
Kimi Raikkonen was due to be back in the Lotus for the first time this week after
Romain Grosjean ended his test with the quickest time on Friday, but the Finn was taken ill with suspected food poisoning and will be replaced – for the morning at least – by test driver Davide Valsecchi.
Grosjean is set to return to the circuit for the afternoon having already left for home following the conclusion of his programme.
Elsewhere, there is a debut in Marussia colours for Jules Bianchi, who was
named as Luiz Razia's replacement on Friday evening.
Williams will split its running between Pastor Maldonado and Valtteri Bottas.
