Kimi Raikkonen fastest as McLaren woes continue

Kimi Raikkonen returned Ferrari to the top of the pecking order on Thursday as McLaren registered just three laps.

A lap of 1:23.477 from Raikkonen on Pirelli's new ultra-soft tyre put Ferrari top of the standings, though the Finn spent much of the afternoon in the garage, suggesting he could have finished the day with more than his 79 laps. Of bigger note was McLaren's lack of activity after three installation laps. Fernando Alonso was the first man out of the garage in the morning, with the team clearly keen to make up for Wednesday's lost running. However, a coolant leak was soon detected and it was severe enough to prevent Alonso from ever returning to the circuit -- a massive blow for the team with just four days of testing remaining until Melbourne.

Daniil Kvyat finished second with an ultra-soft run of his own, finishing eight tenths down on Raikkonen and ending the day with a healthy 95 laps to his name. Force India's development driver Alfonso Celis ended his second day in the car in third position, posting a time of 1:24.840 on the super-soft tyre at the end of a 75-lap day with the VJM09. Kevin Magnussen continued Renault's recovery from its troubles on Monday and Tuesday, which saw Jolyon Palmer complete just 79 laps, as he racked up 152 in the RS16 and finished third thanks to a lap on the soft tyre. His day ended with a stoppage in the final 15 minutes at the exit of Turn 3.

Toro Rosso's Max Verstappen continued the team's healthy mileage collection this week with 110 laps . Felipe Nasr also had a productive day with the Sauber, accumulating 119 laps in the team's 2015-spec car to give it plenty of comparative data for the launch of this season's car next week.

World champions Mercedes split the day between its drivers for the second day in a row. Lewis Hamilton fell one lap short of a century in the morning, while Nico Rosberg added 86 overall, helping the world champions on to 671 laps-- past 3,000km -- for the first four days. The team spent much of the day trialling its radical new nose design, which includes an S-duct.

Felipe Massa had another stop-start day and completed just 53 laps for Williams. Newcomers Haas executed a race simulation with Esteban Gutierrez, as he surpassed the team's previous best lap tally and completed a race simulation. The only blemish was a late stoppage for the Mexican driver caused by an electrical issue in the final hour but it should not dampen what has been an encouraging start to the team's life in F1. Manor rookie Rio Haryanto ticked off 51 laps on his second day with the MR05 finished with a spin into the wall at Turn 4 in the afternoon.
