Raikkonen ended the final day of winter testing at the top of the timesheets while Mclaren had yet more woes with little time left before the season opener.
It took just 7 laps for the Renault engined Mclaren to cut out for a fifth time this week meaning the mechanics needed to put another new engine in.
He was unable to get back out before the lunch break and so ended the morning with his seven laps.
Grosjean was closest to Raikkonen who had set the morning pace but was 1.369 seconds behind the Finn.
Kubica was supposed to run today but sacrificed the day so Sirotkin could run in the morning with Stroll taking his afternoon slot.
Leclerc was slowest of the eight drivers who set a time in the morning with 18 laps, he did, however, spin into the gravel at turn 12 causing a red flag. Hamilton meanwhile only completed race runs as such he set the most laps of the morning with 97.
Sainz had gearbox problems and so only managed 4 installation laps before 1pm.
Sainz did, however, make it back out in the final half an hour and set a time good enough for second only for Alonso to go faster.
The latter had a much more productive afternoon making up for his morning stoppage adding another 86 laps to his tally. His hypersoft time of 1:17.784 was half a second slower than Raikkonen’s morning benchmark.
Bottas ran the Mercedes in the afternoon session and with 104 laps under his belt, Mercedes broke the 200 barrier for total laps.
The Haas of Grosjean, however, completed 181 laps and landed the fifth fastest time behind Ricciardo.
Stroll took over Williams running but set the slowest time and only managed 27 laps.
Final results are as follows
