Robert Kubica put Renault at the top of the timesheets in the third and final day of testing at Valencia, making it a different team at the top each day. The Renault has been the talk of the test with it's innovative and unusual exhaust system, and the car hovered around the top of the timesheets before Kubica grabbed top honours towards the end of the day.

Sutil led the timesheets for a good proportion of the day, giving Force India some much-needed exposure, whilst Jarno Trulli was stuck in the slower times. The power steering on the Lotus was not fixed in time, so Trulli completed just under 40 laps without setting a laptime, and more crucially, without any assistance at the wheel.

Massa was in trouble early on when he had to pull to a halt out on track with smoke pouring from his Ferrari. Flames were spotted in the vicinity of the prancing horse, and there was a twenty-minute red flag while the car was rescued. Massa wasn't seen out on track again until well into the afternoon.

With three days of testing complete, we are none the wiser in terms of times and pace, but it has been interesting to see who has had problems, and which teams are being vocal about which parts of their plan. More to come next week when the testing moves on to Jerez.
