Kimi Raikkonen is missing from the penultimate day of testing in Barcelona after illness forced the Finn to withdraw from his first planned day of action this week.
Raikkonen was due to take over from Romain Grosjean
behind the wheel of the E21 on Saturday but has been hit by suspected food poisoning; forcing him to inform the team that he wouldn't be able to drive.
As a result, Lotus test driver Davide Valsecchi is on track this morning for his first taste of the new car.
Following the conclusion of his programme on Friday, Grosjean had left the circuit to return home but is now expected to return to Catalunya to get back behind the wheel on Saturday afternoon.
