BMW Sauber's Robert Kubica was third fastest, albeit half a second down on Raikkonen, appearing to underline the German manufacturers have fallen off the pace set by Ferrari and McLaren in the Turkish Grand Prix at the weekend.

Britons David Coulthard and Jenson Button were fourth and fifth for Red Bull and Honda on the unofficial timesheets, followed by Sebastien Bourdais for Toro Rosso.

On home turf, the Frenchman at least did not wreck the new STR3 as he did on the car's debut in last month's test in rcelona, which forced the team onto the backfoot.

Jarno Trulli was seventh in his Toyota, with under-pressure Nelson Piquet in close attendance in his Renault.

The Brazilian completed a remarkable 193 laps, almost 700kms, as he looks to atone for a poor start to his rookie season.

Williams' Kazuki Nakajima was ninth fastest of the 11 drivers on view as Force India's Adrian Sutil and Giancarlo Fisichella split their team's driving duties, and were 10th and 11th respectively.

To conclude the test, the teams will on Friday use a different configuration of the track to replicate aspects of the Gilles Villeneuve circuit in Montreal for next month's Canadian Grand Prix.
